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...
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...
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?
I don't have a photo of it but from left to right it is main switch, RCD 1 63A 30mA, 5 MCB's RCD protected, RCD 2 63A 30mA (this is the one that trips), 3 MCB's RCD protected, 32A MCB feeding motor, 16A MCB feeding different motor both 32A and 16A MCB's fed directly from main switch. Mainly old...
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...
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?
Just thought I would post a warning about this company, They are a facilities management company based in Oxfordshire and I got a call out of the blue from someone called Will Simmonds a couple of months ago. He wanted me to do a couple of jobs at an opticians in Bath, it actually fitted in with...
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...
