How to wire a Schuko plug: sheath, earth, then stop

Updated: 23 October 2026

You are holding a rewirable plug, a rubber coupling, or a screw-lid converter. How to wire a Schuko plug starts with that part, because the three bodies do not share one set of screws. This page is the order of work and the stop line, not a ranking. The listings sit on the [Schuko plug comparison](/hub/sockets-and-extension-leads/schuko-plug). A qualifying purchase can earn us a commission at no extra cost to you. Notes use the amazon.co.uk listings of 21 October 2026 and public UK safety guidance. Nothing was checked on a bench.

What you are fitting

Unplug first. Fixed wiring is an electrician’s job. The Brennenstuhl at £5.19 is a male plug you wire: types E and F, 230 V, 16 A, sheath 6–13 mm. The as-Schwabe 60415 at £5.99 is the female coupling, conductors up to 2.5 mm². A one-wire field is not an earth diagram. Mr. Gadget’s ST-6 at £8.49 does not ask you to strip the flex. You seat the existing plug under a lid. The Schuko plug buying guide separates those three jobs.

Earth, brown, and blue

Green and yellow is earth. Brown and blue are the poles. Put earth on the earth terminal, the outer sheath in the cord grip, and do not test with the plug in the wall. A BS 1363 plug is polarised. A Type F Schuko plug is not, so do not copy a UK diagram’s left and right. Follow the diagram on the body you opened. The clamp must bite the outer sheath, not the coloured cores.

Closing a UK conversion plug

For Mr. Gadget, power is off, the CEE 7/7 or CEE 7/16 plug goes fully home, and two screws close the lid before the UK face will seat. The stated fuse is a BS 1362 13 A fuse. If the lid will not close, do not pack the gap. VGUARD at £5.99 is a push-in adaptor with a stated 13 A fuse and BS 8546 in the title. You do not screw a lid over it. The stay-or-visit fork is the conversion plug versus travel adaptor page.

When to stop

Stop if the sheath is cut or taped, the earth core is missing, the colours are unclear, or the body is hot. Do not file a round pin into a BS 1363 shutter. IP54 and IP44 on these listings are claims, not a reason to bury the joint. If the flex is sound, the diagram is visible, and the sheath sits in the clamp, close the body.

Common questions

Which colour is earth?
Green and yellow is earth on a harmonised flex. Brown and blue are the two current-carrying cores. Put the earth core on the earth terminal shown on the plug’s own diagram, and leave it slightly longer than the other two so a pull reaches it last. If the flex has no green and yellow core, do not invent an earth with a scrap of wire. That appliance or that cable is the wrong match for an earthed Schuko body.
Does it matter which side gets brown and blue?
On a Schuko plug, live and neutral can swap because the plug can be inserted either way up. You still put brown and blue on the two pole terminals the diagram marks, and you still put green and yellow on earth. What you must not do is copy the left-hand and right-hand layout from a UK 13 A plug diagram. A BS 1363 plug is polarised. A Type F plug is not. If your body has no diagram, stop.
How do I fit the screw-lid converter?
With the appliance unplugged, seat the European plug fully in the Mr. Gadget body, tighten the two screws, and close the lid before you offer it to a UK socket. The listing states a CEE 7/7 or CEE 7/16 plug. If the lid will not close without force, that plug is a poor fit. Do not pack the gap. A loose fit shows up in the reviews, including one intermittent failure.
What fuse goes in the UK converter?
The Mr. Gadget listing states a BS 1362 13 A fuse, and it says to replace that fuse only with the same type. VGUARD’s bullets state a 13 A fuse and do not print the words BS 1362, though UK reviews call it a standard replaceable UK fuse. Do not fit a higher-rated fuse to stop it blowing. A Schuko plug you wire yourself has no fuse in the body at all. The 13 A limit is the UK side, not a suggestion.
Can I file the pins to fit a UK socket?
No. A Schuko pin is round and about 4.8 mm. A UK socket expects rectangular BS 1363 pins and has shutters. Filing, bending, or forcing the round pins is a known dangerous shortcut, and this page does not explain it. Use a conversion plug, a proper UK plug on a new flex, or a travel adaptor for a short visit. If the pins on a plug you already own are bent or blackened, replace the plug rather than reshaping them.
When should I stop and call an electrician?
Stop when the sheath is damaged, the diagram is missing, the colours are unclear, the body runs hot, or the work is fixed wiring rather than a plug on a flex. Also stop if a conversion plug cuts out or the lid will not close on the European plug. Those are not adjustments you make with tape. An electrician, or a replacement flex from the appliance maker, is the next step. Do not keep loading a joint that has already warmed up.
