    Faulty RCCB on old TT system

    I have a problem to sort out - it is a TT system with a faulty 80A 10mA RCCB after the meter and before the consumer unit. The board is very old style MCBs with no RCDs present. The customer called me up because until about 6 weeks ago the front garden lights were causing the RCCB to trip. I...

    Neutral lead on RCBO'S

    What exactly are the neutral leads for? and if a neutral to earth happened on a board with just RCBO'S in it, why doesnt the fault travel along that neutral and affect the other RCBO's?

    Most reliable RCD brand.

    Greetings. There has been much talk of the unreliability of RCD's lately so I was wondering what are peoples thoughts on the most reliable. Do you have a favourite brand? What do you think is the worst brand? I am hearing quite good things about MK brand but they are quite pricey. Thanks.

    What is an RCBO's Functional Earth connection really for?

    Can anyone direct me to a citeable link which explains in detail how an RCBO works, and in particular what the functional earth connection is for please? I was told today by a professional, highly experienced electrical engineering lecturer that it’s only for spike suppression, or bleeding off...

    RCBO's Can the excess wires from them be cut off??

    Hi, I was talking to another sparks that I know, and the conversation swayed onto leaving the wires from the RCBO's and not just cutting them off. The conversation was cut short though and the reasons were not made to me to leave them as is. And seeing another thread in the 'Electricians Arms'...

    Hello All. I have recently rewired a house, and fitted a TD-Line CU (main switch and all RCBO's). All has been fine until now, 1x 6a RCBO for the kitchen and TV room lights has started making a sort of buzzing/humming noise. I haven't heard it myself but the client says that it isn't very...

    RCBO's

    Why do manufacturers give RCBO's curly neutral cables? When you fit them into the board they look a right mess, especially when there are a lot of them. If they were given straight neutral cables you would be able to dress them all neatly down to the neutral bar just as you do with your...

    Hazardous Area / RCBO use

    I've heard somewhere along the line that using Schneider / Merlin Gerin RCBO's is not recommended for RCD protection, in my case I'm referring specifically for protection of circuits within hazardous areas. Infact, I believe in the same conversation there was mention that RCBO's had been banned...
