Hello.
I'm in the process of putting power to someone's shed. As they wanted sockets and a light (greedy! :^O ) I've put a small consumer unit in the shed with an RCD and 2 mcbs.
I've run the cables supplying the shed from a consumer unit that had a space on it in their main building. It was another small cons unit on which the other mcb is for the washing machine.
The building is on 3 phase supply but the half of the building that I'm working in is only one of the 3 phases as the building used to be split into 2 units but is now one. Its on a TN-S system. The small existing consumer unit (the one with the washing machine mcb on it) has no main switch before it (the incoming line is not able to be switched off) as I found out today (don't worry I was using my fused test leads!)
Now I need to test.
Can anyone tell me where I test from? And what I should test? Obvoiusly not the whole thing as I didn't build it but I do need to test my work in the shed. I also need to make sure the cable I put to the shed is ok.
Can I test from the "washing machine" cons unit and through my cons unit in the shed or will that upset the RCD on the cons unit in there?
Ze? Where do I test that from? (I know in theory but which bits do I actually test from?)
Help is required ASAP please as I would like to test tomorrow!
Thank you!
