    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...

    RCBOs - Fly Leads

    Folks, What do you guys do when the fly leads on RCBOs are too short? The neutrals are usually OK but the earths rarely seem to reach. I have to fit 5 RCBOs in a single Hager CU next week and wanted it to be tidy. Ta!

    RCBOs . . . all tripping at same time.
