    Mobile bar needed wiring

    Does that not apply to the supply . I am only wiring the unit . I will not be connecting it as it will be going out with an outdoor catering company who I assume will take responsibility for the connection.

    Mobile bar needed wiring

    been asked to wire a mobile bar. 16 amp commando plug supply onto a small board with rcd30ma. Wire all lights and a few sockets in braided flex. Equipotential bonding on structure.

    3 rcbos tripping at different times

    Thanks to all who have given their advice. I am going on Monday to see what's going on. It's a good starter to strip it down and check each ring as you said. Can I let you know what sorts it . Always nice to hear differing views on faults . It's a learning curve even for the older generation

    Two consumer units backfed

    Exactly. But who is going to find a fault that until I arrived , no one knew existed , and will they let me turn off all the sockets in the house, or pay me to put right something that never existed until I turned up, on a never ending goose chase around the house

    Two consumer units backfed

    That's fine but if you put all the sockets in the house on a 20 amp breaker then it's asking for trouble. Thanks for replying without a small amount of sarcasm

    Two consumer units backfed

    I have just come across a domestic installation that has two consumer units I was asked to wire extra sockets and do a board change as well. I found that the sockets of one board circuit are interconnected to a circuit from the other board, thus back feeding each other. This means that unless...
