Did a wee job for my neighbour yesterday...extending a ring to incorporate a double socket...didn't have the Wago box size I wanted, just a bigger one, but it's behind a dishwasher...
No earth on the existing socket, but hey...the CPCs had just fallen out of the terminal, so easily fixed...
Got a Schneider box, bunged the 221s in, the lid is quite deep, so it all fitted, just, after some squeezing...all worked fine, tested ok, plenty space behind the d/w...and then saw there was a 700mm worktop, so a Wago XL would have fitted in fine on the back wall,...
Look...look...look again! My knees though...
Going back on Monday to make a proper job of it!
Was a bit worried that the socket had a spur through a white, round JB...but it's all ok...that spur just feeds the double socket in the living room...and only a TV, sound bar, HiFi system, Alexa, an 8-way power strip, into which is plugged a 6-way...two heaters. 2 table lamps, the Christmas tree...
Honestly, the previous owner was nuts! Every time I go there I find sh*t that would make you cringe! However, at least he used H0RN5 flex from the JB through the wall to the socket! Obviously knew the d/w might leak at some point...
