    Merlin Gerin MCB

    Does any know of any RCBOs which will fit alongside these breakers? Kitchen upgrade and I’ve told them kitchen sockets need rewired alongside putting on rcd protection. Also recommended the whole board to be changed which they only want anything doing that’s involving kitchen.

    UK Fixed load mcb

    hi all, I've been asked by a chippy mate to install an extractor in his workshop. Had a look at the spec and its 2.2kw so nothing major. Spec say to install on a 16a socket protected by a 30a d type mcb. Ideally then a 2.5mm radial and 16a cform. I understand the 30a d type is for start up and...

    Suitable MCB for Radial Circuit?

    Hi all, I am installing a Radial A2 circuit which by rule it should have an MCB of 32Amps, but when I reference the table 4D1A using reference method A or B, current are 26 and 32A respectivitly.. So the question is why we go for a 32A mcb and not 25A one? Thanks

    125A D Type MCB keeps tripping on a heater element circ

    I changed 3 x 125A fuses for 3 x 125A D type MCBs (ABB). They held for a day and then two started tripping, we didn't have any spare 125A, so we fitted 100A C type and the issue has disappeared, can anyone shed any light on this for me please?

    1mm cable on a C curve 6amp mcb ?

    So I was chatting with a friend tonight (also an electrician) and we were talking about disconnection times of C curve MCBs (as you do) and he was convinced he had a distant memory that 1mm t&e cable couldn't effectively be protected by a C curve 6amp mcb but couldn't give me a good reason. I've...
