I was called out to one of my commercial customers today,,, no power in some sockets "a fuse has blown" they said... Well I get there to see the cover of the old MEM BS88 3ph board open and while discussing their problem I had to slap their hands several times as they were poking their fingers into the board:O

Anyway while talking to them they also said "do you think it coud be this?" and pointed to a tripped RCD in a single phase board...

After resetting the RCD I went around with my socket tester to see if it actually was what had caused the problem,,, it was!! But I also found this

Something that I have not said is that this is a council owned property which is let out to a local community project so in theory no DIY should have been carried out.

BTW I removed the socket, joined the cables and fitted a blank plate

Whats going on there? conduit installation with the conduit as the earth and socket been brought forward into a surface box without a cpc. Or has someone been wiring sockets ans snipping cpcs off?

It's from the new range of top quality marbo sockets... they don't need earths

Nice lol. So what caused the RCD to trip Noz?
