    Testing old MCBs to check they operate correctly

    As far as i know, there is no way of checking an MCB for correct operation. Then today, i've been told you can do it by placing the breaker under load and using an EFLI tester to do it. How the hell would this work, sound like bull to me.:rolleyes:

    Starbreaker MCBs

    This is a really basic question. I have an old Crabtree Starbreaker c/u (dated 1992) that uses mcbs that slot in. Is there a recommended method to remove them as obviously I do not want to use unecessary force. The instructions tell how to intstal them but not to remove. Thanks, Paul

    Using MCBs instead of switch fuses on tail extensions????

    If you extend meter tails more than 3m you need a switch fuse, right? Would you be able to use, say, a 100A DP MCB in an enclosure instead? If not, why not? Ta.

    Siingle phase MCBs for a three phase socket

    Can anyone find a problem in using single phase MCBs for a three phase socket. I would consider it bad practice and prefer a 3 phase MCB. Doing a PIR and cant find anything in the regs to fail it.
