    Single or double pole RCBOs???

    Installed a garage CU, 2 way. As the house is TNC-S an earth rod has been installed, which is giving an Ra of 102 ohms. The supply to the garage is protected by a MCB on the non RCD side of the CU, as installation methods don't require RCD protection. The circuit in the garage has been...

    Is double pole isolation needed?

    Basically need to wire a shed 6mm swa into the non rcd side of a CU straight into a MCB. Garage will have its own RCD protected CU. Just wondering if double pole isolation is needed at both end of the SWA? Thanks

    double pole switch

    Was wondering what the proceedure was for changing a consumer unit. I was under the impression I could request EDF to install a double pole switch so I'm not messing about waiting for someone to come and pull the main fuse (or to break the seal and do that myself). I called EDF and they said...

    4 Pole 100A 300mA RCD ????

    Does anyone know if it is possible to get a 4 pole 100A RCD (3L & N) with 300mA trip? Also needs to have time delay. Not too much to ask is it?:D Cheers
