    EICR specs for these RCBO's

    I'm doing an EICR at the moment, I don't normally do them and don't enjoy it, but beggars can't be choosers! I've come across some RCBO's I've not seen before, they are federal stablock type with a neon in the test button that lights up when they trip. Does anyone know the facts and figures...

    Why the disparity in prices of RCBO's?

    As in the title. I usually fit dual RCD boards, however I have recently fitted a few RCBO boards due to space restrictions. To obtain a reasonable price for the customer I have been fitting Lewden RCBO's, as at £10 each they are affordable. Why do RCBO's have such a difference in price...

    Purpose of earth fly leads on RCBO's

    Domestic 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...

    All Rcbos

    RCBO trip times - no, not the usual what should it be . . .

    I was doing a board change today and 10 out of the 15 RCBO's were returning a value in the region of 19ms at 1x and 30 at 5x. Tried more than 1 MFT (both Metrel but got the same sort of results). So this is still within the 40ms's but with new RCBO's would you personally accept or return them?
