    Will an RCD offer any protection in a building with NO earth circuit?

    I live in Phnom Penh, Cambodia and people die here regularly by electrocution. There is no earth wiring in the buildings, just live and neutral. I am a member of an expats forum and the question arises: Will using an RCD device offer any protection at all? I understand RCD's will go off with...

Hoping someone might be able to explain a few things to me as I need a bit of reassurance regarding RCD ratings. I'm currently at a relative's...

    EICR - Unsatisfactory - No RCD - C2

    Hi all, have just ordered my first EICR ever for a studio to 1-bed conversion flat in London. It cost a little less than £80 and the electrician had great reviews on the site I booked him on.

    Why is oven tripping rcd?

    Every time oven gets to temperature it trips the RCD. Thought the oven must be knackered so got a new one. That does the exact same thing. Any ideas? I should add that this is a brand new house. Just moved in yesterday

    I am to install a car charger that states a type A RVD is to be installed. Can this be put in the garage from the non rcd side of the board or is it better to change the RCD on the board and use that side. I assume it makes no difference
