Overview
The short answer, then the detail.
A Caution 415 Volts sign warns of the electrical voltage present and the risk of shock. It uses the ISO 7010 W012 electricity symbol. Sizes A4 (210 × 297 mm) to A1 (594 × 841 mm) in 3mm Foamex, 3mm Dibond aluminium composite and self-adhesive vinyl. UK mainland delivery £7.95, free over £99; no VAT added.
"Caution 415 Volts" is a message people need to take in at a glance. This sign warns of the electrical voltage present and the risk of shock and suits substations, switch rooms, distribution boards and plant rooms. The design uses a yellow warning triangle with black text, with the ISO 7010 W012 (Electricity) symbol.
It states the supply voltage, 415 volts, so anyone opening the door or enclosure knows what is behind it.
The Health and Safety (Safety Signs and Signals) Regulations 1996 require a safety sign wherever a significant risk remains after other controls, and live electrical equipment is a common example.
You can have it printed on 3mm Foamex (rigid PVC foam board), light and easy to fix indoors or for short-term outdoor use, 3mm Dibond aluminium composite, rigid and weatherproof for long-term outdoor use and self-adhesive vinyl for smooth walls, doors, glass and equipment. Indoors, Foamex or vinyl is usually all you need.
Caution 415 Volts Sign: sizes and materials
Choosing a size: we allow about 1 metre of viewing distance for every 25mm of sign height, based on the distance-factor method in ISO 3864-1. That gives A4 (210 × 297 mm) (reads at about 8 m), A3 (297 × 420 mm) (reads at about 12 m), A2 (420 × 594 mm) (reads at about 17 m), A1 (594 × 841 mm) (reads at about 24 m).
Where to put it: On the door or enclosure of the electrical equipment.

Which size do I need?
A safety sign must be large enough to read from where people will see it. Our conservative guide, based on the distance-factor method in ISO 3864-1, is about 1 metre of viewing distance for every 25 mm of sign height (the shorter side). Use it with your own risk assessment.
| Size | Readable from up to about |
|---|---|
| A4 (210 × 297 mm) | 8 m |
| A3 (297 × 420 mm) | 12 m |
| A2 (420 × 594 mm) | 17 m |
| A1 (594 × 841 mm) | 24 m |
Well lit or internally lit signs can be read from further away; dim areas need larger signs.

Where should the Caution 415 Volts sign go?
On the door or enclosure of the electrical equipment. Keep it clear of anything that could block the view.
Is a Caution 415 Volts sign a legal requirement?
The Health and Safety (Safety Signs and Signals) Regulations 1996 require a safety sign wherever a significant risk remains after other controls, and live electrical equipment is a common example. Your own risk assessment decides where signs are needed.
Can you change the wording or add our logo?
Yes, as a custom job. Tell us the wording you need instead of "Caution 415 Volts", or send your logo, using the question box on this page or by calling 0161 315 1151.

Indoors, 3mm Foamex is light and easy to fix. Self-adhesive vinyl suits smooth doors, glass and machinery. Choose Dibond aluminium composite if the sign will be outside or needs to be tougher.
How do I fix it?
Rigid boards are supplied undrilled. Fix them with sign-mounting tape, screws through holes you drill, or cable ties on fencing. Vinyl is self-adhesive and goes onto clean, smooth, dry surfaces.

Questions
Buyer questions about this product, answered. Can't see yours? Ask below and our team will reply.
How far away can the Caution 415 Volts Sign be read?
Work back from how far away people will be when they need to read it. Using our guide of about 1 m of viewing distance for every 25 mm of sign height: A4 (210 × 297 mm) reads from about 8 m, A3 (297 × 420 mm) reads from about 12 m, A2 (420 × 594 mm) reads from about 17 m and A1 (594 × 841 mm) reads from about 24 m. In poor light, or where people are moving quickly, go a size up. The guide is based on the distance-factor method in ISO 3864-1; use it with your own risk assessment.
Which sizes can I order the Caution 415 Volts Sign in?
The Caution 415 Volts Sign comes in 4 listed sizes, from A4 (210 × 297 mm) at £5.28 up to A1 (594 × 841 mm) at £15.91. In between: A3 (297 × 420 mm) and A2 (420 × 594 mm). Prices are the lowest option for each size.
I do not have artwork. Can you design it for me?
The Artwork choice on this page offers: "I will upload print-ready artwork" (free), "Add my text and logo to a clean layout (typesetting)" (£15), "Design it for me from my brief" (£35), "Redraw or vectorise my logo from a low-res file" (£50) and "Design a new logo for me" (£100). Design fees are fixed, show as their own line in the basket and cover the whole quantity of that item. Typesetting includes 1 proof and 2 rounds of changes; design from your brief includes 1 design and 2 rounds of changes. The Caution 415 Volts Sign is printed on 3mm Foamex, 3mm Dibond aluminium composite and self-adhesive vinyl.
How much does the Caution 415 Volts Sign cost?
The Caution 415 Volts Sign starts from £5.28 with size A4 (210 × 297 mm) and material self-adhesive vinyl on the Saver turnaround. The price in the calculator changes live as you pick the size, material, finishing, quantity and turnaround, so you see the final price before you add to basket. No VAT is added because we are not VAT registered. Delivery is added at checkout: UK mainland delivery is £7.95 per order and free when your goods total is £99 or more after any discount code (artwork and design fees do not count towards it).
How long does the Caution 415 Volts Sign take to make?
On the option the calculator opens on, Saver is ready to dispatch in 6 working days, Standard in 4 and Express in 2. These are working days to dispatch, counted from when your order and artwork are confirmed, and other sizes or materials can take a day more or less: the calculator shows the exact days next to each turnaround. Courier delivery usually takes 1 to 3 working days after dispatch, and we email the tracking details when the parcel leaves us. The Caution 415 Volts Sign starts at £5.28 before delivery.
Do you charge for delivery?
UK mainland delivery is £7.95 per order and free when your goods total is £99 or more after any discount code (artwork and design fees do not count towards it), so one sign at £5.28 on its own pays £7.95, and the charge disappears once your basket reaches £99. Mainland Scottish Highlands postcodes add £10 once per order. Northern Ireland, the Scottish islands, the Isle of Man, the Channel Islands, the Isles of Scilly and the Isle of Wight are quoted before you order.
What type of sign is the Caution 415 Volts Sign?
"Caution 415 Volts" is a warning sign: a yellow triangle with a black border, warning of a hazard. It carries the ISO 7010 W012 symbol (electricity), so people understand it even if they do not read English. The colours and shapes follow the scheme set out in the Health and Safety (Safety Signs and Signals) Regulations 1996.
Can I get the Caution 415 Volts Sign as a sticker?
Yes. Choose self-adhesive vinyl in the material options and the sign arrives as a sticker to peel and apply. It suits doors, glass, machines, cupboards and smooth painted walls, where a board would be awkward to fix. Clean and dry the surface first and smooth it on from the middle outwards. For rough or dusty surfaces, choose a board instead.
How thick is the Caution 415 Volts Sign?
The board options are 3mm Foamex and 3mm Dibond aluminium composite, so the board version is 3 mm thick. The self-adhesive vinyl version is a thin film that sits flat on the surface. Dibond is two thin aluminium skins with a plastic core, so it is rigid but still easy to fix. Foamex is a light foamed PVC board.
Can the Caution 415 Volts Sign be used outside?
Yes, in the right material. Dibond is the best choice for signs that stay outside long term. Foamex copes with sheltered outdoor spots but is happiest indoors. All printed signs fade slowly in strong sun over time; check them as part of your routine and replace any that are hard to read. The Caution 415 Volts Sign is printed on 3mm Foamex, 3mm Dibond aluminium composite and self-adhesive vinyl.
Will the Caution 415 Volts Sign show up at night?
Only where there is light on it. We print on 3mm Foamex, 3mm Dibond aluminium composite and self-adhesive vinyl, which are not reflective or glow in the dark. For car parks, yards and routes used after dark, position signs under existing lighting, or light them. Where your risk assessment calls for reflective or photoluminescent signs, you will need a specialist supplier.
How do I fix the Caution 415 Volts Sign to a wall or fence?
Foamex and Dibond boards can be screwed to a wall through holes drilled near the corners; use washers and do not overtighten, especially on Foamex. On smooth indoor walls and doors, double-sided foam tape or adhesive pads avoid drilling. On fences, drill the board and cable tie it through the holes. The vinyl version simply peels and sticks to a clean, dry, smooth surface. The Caution 415 Volts Sign is printed on 3mm Foamex, 3mm Dibond aluminium composite and self-adhesive vinyl.
What happens if my file is not good enough to print?
Our file check catches the usual problems: the wrong size, no bleed, low resolution images and text too close to the edge. We tell you what needs fixing before anything is printed, and you can send a new file. If you would rather we sort it, the typesetting option (£15, 1 proof and 2 rounds of changes) sets your text and logo on a clean layout. For the Caution 415 Volts Sign, set your file up at the size you order, for example A4 (210 × 297 mm).
Can I order now and send my artwork later?
Yes. You can upload your file on the product page, or place the order and upload later: we email you after you order. Your designer can send the file to us by email or WhatsApp with your order number, so it does not have to come through you. The turnaround clock starts once your order and artwork are confirmed, so send the file early if you have a deadline. The Caution 415 Volts Sign comes in 4 listed sizes, from A4 (210 × 297 mm) to A1 (594 × 841 mm).
What file should I upload?
A PDF at the finished size is best, with fonts embedded or converted to outlines. We also take AI, EPS and SVG, and high resolution JPG, PNG or TIFF files. Word, PowerPoint and Canva files are fine as a starting point, but export a full-quality PDF if you can. You can upload up to 3 files of 25 MB each on the product page, or upload later: we email you after you order. The Caution 415 Volts Sign is printed on 3mm Foamex, 3mm Dibond aluminium composite and self-adhesive vinyl.
Do you check my file before printing?
Yes. A person from our team checks every uploaded file for size, bleed and resolution, and tells you if something needs fixing before anything is made. We print what you supply, so check spelling, phone numbers and dates yourself too. Production starts once your order and artwork are confirmed. The Caution 415 Volts Sign is printed on 3mm Foamex, 3mm Dibond aluminium composite and self-adhesive vinyl.
What resolution does my artwork need for this sign?
For items read close up, aim for 300 dpi at the finished size. At 300 dpi an A1 (594 × 841 mm) design needs about 7,016 × 9,933 pixels. Logos and text are best as vector artwork, which stays sharp at any size. Photos taken from websites or social media are usually far too small; our file check flags images that may print soft.
Will the price change at checkout?
Only delivery is added. The goods price you see in the calculator is final, with no VAT added. UK mainland delivery is £7.95 per order and free when your goods total is £99 or more after any discount code (artwork and design fees do not count towards it). Any artwork or design fee you choose shows as its own line in the basket, so you can see exactly what you are paying for. The Caution 415 Volts Sign is printed in our Manchester workshop or by our UK production partner, depending on the size and material.
How do I order several of this sign?
The price shown is for one sign in the size and material you pick. Set the quantity box next to Add to basket and the basket multiplies it. If you need several different sizes or materials, add each one to the basket separately. One artwork fee covers the whole quantity of a line, and "Same artwork as another item in my basket" adds no second fee. For large runs, ask for a quote. The Caution 415 Volts Sign comes in 4 listed sizes, from A4 (210 × 297 mm) to A1 (594 × 841 mm).
Do you deliver Caution 415 Volts Sign to the Scottish Highlands?
Yes, with a difference in price. Mainland Scottish Highlands postcodes, for example around Inverness, Fort William, Oban and Thurso, pay the mainland rate plus £10 once per order, even when the order qualifies for free delivery. Northern Ireland, the Scottish islands, the Isle of Man, the Channel Islands, the Isles of Scilly and the Isle of Wight are quoted before you order: use Get a quote or call 0161 315 1151. We do not deliver outside the UK. On the opening option, the Caution 415 Volts Sign is ready to dispatch in 6 working days on Saver or 2 on Express.
Can I pay for express production on the Caution 415 Volts Sign?
Yes. Express makes this sign ready to dispatch in 2 working days on the opening option, priced at £7.03 against £5.28 on Saver (6 days). To plan back from a date, add 1 to 3 working days for the courier after dispatch and allow for artwork: production starts once your order and artwork are confirmed. If the date is very tight, call 0161 315 1151 before you order.
How do the material prices compare on the Caution 415 Volts Sign?
At A4 (210 × 297 mm): 3mm Foamex £29.26, 3mm Dibond aluminium composite £42.94 and self-adhesive vinyl £5.28. The gap stays similar on bigger sizes, which the Prices by size table on this page shows in full. Choose on where the sign goes rather than price alone: the cheapest material is not always the one that lasts in that spot.
What other signs go with the Caution 415 Volts Sign?
Signs that are often needed alongside it include Caution Overhead Cables Sign, Danger Buried Cables Sign, Danger 240 Volts Sign and Danger 400 Volts Sign. Each has its own page with sizes, materials and live prices, and ordering them in the same material keeps a set looking consistent. Add them to one basket: delivery is charged once, and it is free once the goods total reaches £99. The Caution 415 Volts Sign is part of our Electricians range.
Is Caution 415 Volts Sign suitable for electricians?
"Caution 415 Volts" is a message people need to take in at a glance. It is part of our Electricians range, which gathers what electricians order for installation, testing and inspection work. Other items in the same range include Car Door Magnetic Signs, Magnetic Van Signs, Danger 11,000 Volts Sign and Danger Electric Shock Risk Sign. You can mix items in one basket, and delivery is free once the goods total reaches £99. The Caution 415 Volts Sign is part of our Electricians range.
Is the Caution 415 Volts Sign portrait or landscape?
This design is portrait, in A4 (210 × 297 mm), A3 (297 × 420 mm), A2 (420 × 594 mm) and A1 (594 × 841 mm). Portrait suits doors, posts and narrow wall spaces. If you need the other way round, choose a design option and we will lay it out for you.
Can I get the Caution 415 Volts Sign bigger than A1 (594 × 841 mm)?
The largest listed size is A1 (594 × 841 mm), from £15.91. For a bigger sign, use Get a quote with the size, material and quantity, and we will price it. Boards larger than A0 travel as oversize items, which adds £15 once per order.
Will this sign bend or bow in the sun?
Foamex is a foamed plastic, so in strong sun and heat a large, thin board can bow, especially if it is only fixed at the corners. Dibond has aluminium skins and stays flat, which is why it is the choice for long-term outdoor signs. Fixing Foamex flat against a wall, or choosing a thicker board, keeps it straighter. The Caution 415 Volts Sign is printed on 3mm Foamex, 3mm Dibond aluminium composite and self-adhesive vinyl.
Can I put the Caution 415 Volts Sign on a door?
Yes. Self-adhesive vinyl is the neatest choice for doors and glass panels. A 3mm Foamex board with double-sided foam tape also works well on a flat door. Place it at eye level on the push side or beside the door, where it is not hidden when the door is open. If the door is a fire door, check with whoever manages it before screwing anything into it.
Can I trim or drill this sign myself?
Foamex and Correx cut with a sharp craft knife and a straight edge: score a few times, then snap or cut through. Dibond has aluminium skins, so it needs a fine-toothed saw and a steady hand. Drill fixing holes with an ordinary drill bit, going slowly, and keep holes at least 10 mm from the edge. Cutting into the print loses the bleed, so allow for it in the design. The Caution 415 Volts Sign is printed on 3mm Foamex, 3mm Dibond aluminium composite and self-adhesive vinyl.
Can I have the Caution 415 Volts Sign in another language, or in two languages?
Yes. Choose "Add my text and logo to a clean layout (typesetting)" (£15) and send the wording in each language; you get 1 proof and 2 rounds of changes. Keep the symbol and the sign colours the same so the meaning stays clear to everyone. Please send the translation yourself: we lay out the text you give us, we do not translate. The Caution 415 Volts Sign comes in 4 listed sizes, from A4 (210 × 297 mm) to A1 (594 × 841 mm).
Will this sign be easy to read for people with poor sight?
Strong contrast, a plain bold typeface and a size to suit the viewing distance make the biggest difference. Our standard safety sign designs use the high-contrast colour pairs set by the safety sign scheme. Place signs at eye level, well lit and without glare, and keep the wording short. For the Caution 415 Volts Sign, set your file up at the size you order, for example A4 (210 × 297 mm).
Can I change my artwork after ordering?
Contact us straight away on 0161 315 1151 or WhatsApp with your order number. If production has not started we can take a corrected file, or cancel the order and refund you in full. Once production starts the order cannot be changed. Printing that matches the design you approved or the file you supplied is not a fault, so check spelling, phone numbers and dates carefully before you order. The Caution 415 Volts Sign starts at £5.28 before delivery.
Can someone help me choose the right options for this sign?
Yes. Call us on 0161 315 1151 or message us on WhatsApp and tell us where the sign will go, how long it needs to last and your deadline. You can also ask a question on this page; our team answers and the question may be published to help other buyers. For a price on something the calculator does not cover, use Get a quote. The Caution 415 Volts Sign is printed in our Manchester workshop or by our UK production partner, depending on the size and material.
Can I order several different designs in one order?
Yes. Add each design to the basket as its own line with its own file or online design, then check out once. Delivery is charged once per order, and becomes free when the goods total reaches £99. If several lines use the same artwork, choose "Same artwork as another item in my basket" so you only pay one design fee. The Caution 415 Volts Sign is printed in our Manchester workshop or by our UK production partner, depending on the size and material.
Can I return this sign if I change my mind?
No. This sign is printed to your order, and the 14-day right to cancel does not apply to goods made to your specification (Consumer Contracts Regulations 2013, regulation 28(1)(b)). You can cancel for a full refund before production starts. If an item is faulty, damaged or not what you ordered, your Consumer Rights Act 2015 rights apply and we reprint or refund. The Caution 415 Volts Sign comes in 4 listed sizes, from A4 (210 × 297 mm) to A1 (594 × 841 mm).
