Hi everyone, new to the forum and have 2 questions.
I have been given a metal shipping container which is to be used as a workshop at the botttom of my garden. it has a relatively new consumer unit and electrics in already.
As it's an all metal body shouldn't the container walls be earth bonded (I assume by a bolt and 10mm earth wire attached to the metal walls and the other end to the earth strip in the cu). The container cu is fed by an armoured cable and the cu is earth bonded to the armouring of that cable and therefore earthed at the house.
Also the 240v sockets (metal mounting boxes and metal face plates - they are all correctly earthed inside each one) are attached directly to the container walls by metal screws. although I appreciate this indirectly creates an earth to the container is this ok or should they be mounted on small wood back plates to insulate them from the metal walls?
Thanks Peter
