    RCBOs with 1 flying wire.

    Do RCBOs normally have 2 flying leads - neutral and earth? Are there "old" rcbos and new types. The reason I ask is that I have bought Proteus RCBOs and they have a flying neutral wire only. I've never fitted RCBOs before and am just a bit confused. Any explanations appreciated. Bul

    Board upgrade to RCBOs

    Hi Im not a spark but a homeowner who is getting quotes for a rewire hoping to start in Dec. One quote has provided an option of upgrading the board to RCBOs for £150. So what does this mean. Do I need it. Is it worth £150 or should it be included from the outset. Many thanks Mark

    CGD CUs and RCBOs. Anyone got any recent experience of them?

    My local supplier is selling CGD RCBOs for £10.99 +VAT each and insulated 8 way consumer unit for £17.99 +VAT. Does anyone know if these are any good or complete carp? I usually use Crabtree gear but customer wants all RCBOs but doesn't want to pay a fortune out as it's a rental property

    RCBO Question...

    Hi when i try to test an RBCO at the DB it trips as soon as the test probes touch the terminals, this only seems to happen with Bill/MEM RCBOs, it doesnt happen with Merlin or Square D. I'm using a standard Robin RCD tester. Any idea why???
