Where Does The Black Wire Go On A Light Switch Uk

By | August 10, 2022



When it comes to lighting, many homeowners are unsure of where the black wire goes on a light switch in the UK. The answer is simple: the black wire is the live wire, which should be connected to the terminal with the “L” marking. If there is no “L” marking, then the live wire should be connected to any other terminal.

It is important to take extra precautions when wiring a light switch in the UK, as failure to do so can lead to serious injury or death by electric shock. Always make sure that both the power supply and the light switch have been switched off before starting. Never work on a live circuit, and make sure the new switch is suitable for the job and doesn’t exceed the amperage rating noted on the box.

Once the power supply is off, connect the wires according to their colours: brown to the live terminal, blue to the neutral terminal, and the green and yellow for the earth. Finally, attach the black wire to the corresponding terminal on the switch. If in doubt, contact a professional electrician, who will be able to install the switch safely and in compliance with the UK building regulations.
