    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???
