    RCBO trip times - no, not the usual what should it be . . .

    I was doing a board change today and 10 out of the 15 RCBO's were returning a value in the region of 19ms at 1x and 30 at 5x. Tried more than 1 MFT (both Metrel but got the same sort of results). So this is still within the 40ms's but with new RCBO's would you personally accept or return them?

    ELI on no trip with Megger MFT

    Does anyone have issues with this test and how accurate is a No trip test? I find my readings seem to change a fair bit testing the same circuit a few times. This is using a 1730.

    3 Phase meter reading correctly?

    Hi Customer has a Polyphase Energy Meter, connected to the incoming 3 phase supply. Her bills are a bit high, but I was wondering as she is only using 1 phase, is there any value (ie cheaper bills) to spreading the load over the other phase's? Any thoughts appreciated
