    retro fitting rcbo's into a non amd 3 board

    Hi guys, I've been asked to do an EICR on a property due to be rented out, and i had a quick visual today prior to booking to do the actual test, i noticed the installation has a starbreaker board with 4 circuits not being protected by rcd, which would obviously be a non-compliance for the test...

    Need a nice to work with CU

    Seeing the PV install is going to be starting soon I thought I'd treat my bungalow to a new CU and replace old 3036 one with an 8 way RCBO board. The only RCD's in the place are the plug top type I have on the extension leads. (Only been in here for a year) I haven't had any dealings with a...

    TT systems and RCBO's

    Why are standard single pole RCBO's not advised for a TT system? Sure I've seen this somewhere....something to do with not disconnecting the N with a N-E fault potentially allowing a fault current to continue to divert to earth from the neutral.. But then a SP RCBO, or MCB on a TN system would...

    Lewden DZ47 RCBO?

    I am looking for an RCBO to fit this board. Do all the breakers with the lewden (or denmans) logo (triangle pointing right in a black oval) have the same fittings? For example some MCB's have 'EC' on them whereas this CU has 'DZ47', also the RCBO's with this same logo do not have any markings...

    RCBO's Vs RCD & MCB

    Can someone assist please? In my strive to understand all things electrical am struggling to find a reason over and above cost why it would be advantageous to use a RCD's and MCB's over a board fitted with all RCBO's? Am I missing something or is it purely economics, the advantage of a pure...

    Hello, I am a diyer doing my own board change shortly (paying a premium for the honour to BC) and have a problem either with my tester or something else. Basically when i test the RCDs and the two RCBOs i have on the board they are tripping on ramp at crazy figures, 6ma on one RCD and 9ma on...

    Any arguments against RCBOs?

    Hi, Just a hypothetical question, more of a homeowner than DIY subject. I'm kind of sorry that when our house was rewired in 2011 we didn't go for RCBOs instead of a dual RCD board, not only is the split of which circuits are on which side not ideal, but it would have saved the width of two...

    No RCBO's = Unsatisfactory

    I've just been to a customer who has had somebody else carry out an EICR and have told them that it can not be passed as satisfactory until they replace a number of MCB's for RCBO's as there is a new law that requires them. This is not just on socket outlets. They have gone all out on cables...

    RCBO's on a TT system.

    Morning all.. I am off sick from work, this rarely happens and already I am bored, so I thought I'd start a thread on the above which i have been thinking about. Question 1: I realise that most on here suggest DP or SPSN RCBO's for a TT, but I am unsure why (with regards the regs)? This is why...
