    Isolate consumer unit help

    Looking to do some work in the consumer unit in my home and was wondering if turning the isolation switch is sufficient as it only appears to isolate live and not neutral? https://ibb.co/R2hLQmR

    How to keep power trips isolated and not trip the whole place when testing faulty appliances?

    Having some 1400W 230V heaters to test and repair that have a power trip problem. I've unplugged all the connections and open them up one by one to identify the part that is causing the trips. Everytime it trips, it trips the whole place through the main circuit breaker. How can I do it safely...

The supply is protected by a 16amp mcb backed up by a 63amp 30mA RCD from the consumer unit which is located in a...

    UK TN-S Looped supply - earth upgrade. Need to isolate neighbour/refer to DNO?

    I have come across what I think is a looped supply - like a normal incomer but two of them coming up side by side. It's a TN-S arrangement with an earth cable looped between the two incomers and on the the consumer unit. Trouble is it's only about 1mm, although I got a decent ZE of 0.35. It...

    When working on circuits do you isolate whole board or just the final circuits using MCBs ?

    When working on circuits do you isolate whole board or just the final circuits using MCBs ? Or is there any instances when the whole board has to be isolated even if you are working on few final circuits? Thanks.

    32 amp rotary isolator

    Anyone know if there is a reg in regards to supply going in to the top of a rotary isolator. We are changing the isolators over for ac units, long story short they won't reach the top terminals now, so feed can only go in bottom. Just a 2.5mm 3 core swa. Cheers

    Schneider board main switch TP-N and 4-pole

    Safety - does switching off at consumer unit isolate the circuit switched?

    I am not an electrician (as you will see from the question!) and I am not planning on doing any electrical alterations. My question is one of safety. I wanted to move a couple of sockets on a kitchen ring main. So I switched off that circuit on the RCD board and all the sockets were then dead. I...
