    What should I do with a new crabtree loadstar board.

    Not sure whether I've asked this or not before but the long and short of it is a while ago I needed to fit a crabtree board at short notice and as I hate using my phone to order stuff I managed to click on the older Crabtree stock which had the AC RCD's in them. I didn't even notice until I'd...

    Will the mini (or larger) RCBO fir in the this starbreaker board?

    2 questions.. 1. Will the mini Starbreaker RCBO's fit in this board? Below is a picture of the board and also the type of RCBO I want to fit in? Thanks :) 2. The existing 100mA RCD is type AC. The RCBO's will be Type A. I have never quite got my head around how this 'incorrect' selectivity...

    Been asked to move, remove and add some sockets the kitchen and I’ll need to add a circuit for an electric hob. Looked at the board and it’s one of those Wylex skeleton boards (image attached).

    What's next to my board?

    Evening all, I'm relatively new to the trade and have just moved house. Looking to rewire and was looking at a few things, could someone tell me what on earth is next to my board? From what I can see is it looks like two contactors? But what are they likely to do?

    EICR code for no upfront rcd on TT split load metal board: poor install

    See this time after time - poor installation: new split load board on a re-wire tt installation. The main switch is not a time delay rcd. The board is metal and there are split load single insulated conductors before the 30mA rcd's. If these conductors touch the metal work the board may...

    Selectivity RCBO Board

    Hi All I'm new here. I have just finished my NVQ and waiting to do my AM2. I have a question on selectivity as it has always slightly confused me, as I've never seen it practically since I started.

    Niglon RCBO stuck in MK LN board

    I had a call to a new customer who was experiencing what sounded like nuisance tripping on a kitchen ring. Some background first. It's an MK LN insulated [i.e. plastic] split load board, with only one side RCD protected. A direct predecessor [I think ?] and very similar in appearance to the...

    Wylex 3 phase board fitting.

    Do I need any more than this to fit the above board, does it need a fitting kit for the switch or anything extra to get it up and running (tails excluded obviously)

    Thoughts on an EICR on this board prior to physical testing.

    Opinions on this Crabtree TP 10 way board? Got to test this next week after a quick recce on a clients site yesterday.
