Dodgey DIY Electrics?

Postby misterg » Sat Jun 30, 2007 9:38 pm


I was changing a socket in a bedroom that didn't work and noticed it was a spur in using 4mm cable instead of 2.5mm. The rest of the ring is 2.5 mm as far as I can see.

Is this dangerous, or did someone just have a bit of spare cable to use up?

The new socket works fine now, but just want to make sure it is safe.

Simply Build It

The thickness of cable used is stated by regulation, the regulations state 2.5mm is the [b]miniumum[/b] that should be used, so 4mm is fine. It does look like someone had a spare bit of wire.

Just make sure your ring circuit is on an MCB (minituare circuit breaker 32amp)

Hope this helps.
