    Motor Tripping RCD but it's not even connected to it

    SOLVED. Thanks to all of you who gave helpful suggestions. I went back yesterday afternoon and tested the IR on the new motor and was all good. So I then disconnected the neutrals of each circuit that was on the tripping RCD and found that with one of the lighting circuits disconnected the RCD...

    Also I think it is very unlikely that PME will be available.

    Motor Tripping RCD but it's not even connected to it

    When I originally installed it the motor MCB was next to the RCD that trips and was in fact fed from the RCD. When we started the motor and the tripping issue arose I moved the MCB away from the RCD and as stated previously I have fed it from the main switch. It is an MK metal clad board so not...

    Motor Tripping RCD but it's not even connected to it

    @JD Hogg If it is a TT system how can you have circuits not connected to an RCD? There is a 100mA RCD before this board but this isn't affected.

    Motor Tripping RCD but it's not even connected to it

    It is an induction motor, The RCD trips when the DOL start button is pressed It is for an apple press It is started with low (no) shaft load I have not taken IR measurements, as I said it's a new motor and even if there was a fault why would it trip the RCD?

    Motor Tripping RCD but it's not even connected to it

    Hi, I have just installed a dedicated 32A circuit to feed a motor which according to the data plate is 3.0kW and 16.6 Amps, single phase. It is fed from a 32A MCB via 6mm cable about 22 metres. I have fed it from a MK twin 63 Amp RCD board but this motor circuit is not protected by either RCD...

    Trades to Site - a Warning

    OK I still haven't been paid or received a reply to my recorded delivery letter. Has anyone out there ever taken a company to small claims court? I'm not sure if it's really worth it?

    Which is the DNO earth block? PME

    I don't have any photos, the tails coming from the original cut out now feed the CU and the meter has been moved to the outside meter box. The neutral and earth are still linked at both points. The work is to change CU so I am wondering whether to allow for running new earth cables back to...
