Title: Earthing back-boxes (patresses) Post by londonman on Feb 6th, 2018, 4:03pm What do the current regs say about earthing these? Just noticed that my electrician didn't earth the ones in the kitchen when he did the second fix. TIA |
Title: Re: Earthing back-boxes (patresses) Post by Lectrician on Feb 6th, 2018, 5:56pm If the back box has one fixed lug (all do these days), then no need to earth the back box. However, the NICEIC still recommend this is done. |

I'm trying to get my head around that. So if you had a metal back box with plastic faceplate are the faceplate mounting screws earthed? Is there always metal on the back of the faceplate that does this? |
