    S-type RCBOs

    Does anyone make S-type RCBOs? For discrimination you should use an S-type RCD to protect a sub-main feeding a CU with a normal 30mA RCD or RCBOs. This can be handled with a 100mA 100mSec S-type RCD. It would be convenient if this were combined with a type B or C 63 amp MCB. This is in a...

    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...

    Square D Quikline RCBOs

    I'm after a 6amp and 32amp rcbo that will fit in a Square D Quikline consumer unit. Does anyone know what replacement breakers fit these boards. I know Schneider took over square d but the acti9 range is Merlin Gerin rebranded.

    All Rcbos

    Someones told me that to comply with the latest regs then a split load board with half the circuits as rcbos & the rest on mcbs with an RCD is no good & all rcbos is the way to go. I can see the point but it seems overkill ???

    So adding a couple of circuits to the garage/workshop (socket radial either side) but having an issue locating some 20A MK C Type RCBOs at a decent non RRP price (I ain't paying £30 odd quid each - yes for my own garage I'm a cheap git :P ) (sockets are for compressor / other stuff with decent...

    RCBOs vs RCDs Pt2

    OK we are told RCBOs are the way to go. Agreed. Because this will do away with using a RCD but, and I guess this has been questioned and possibly answered before, why buy an RCBO that only protects phase side (single pole RCBO) of the cct? Have I missed something? Do we put in one RCD!? Fred

    RCBOs vs RCDs with MCBs

    In a domestic set up ie average (if there is one) house is there any reason you wouldn't use a RCBO but a MCB and a RCD? I can't think one Fred

    Sanity check - replacing MCBs with RCBOs

    Hi All Wanted to get feedback on this idea. I have 3 fuse boards which trip frequently whenever there is a lightening storm nearby. My electrician friend has suggested he swaps all the MCB's with RCBO's so that individual circuits trip rather than the whole board. Each board currently has a...
