Hi folks. Called out to micro tripping rcd occasionally. Customer bought new micro, but that is doing the same. I said, get the new one replaced ...just in case, which he did. Still the same. Only ever happens with the micro
Tested rcd and n-e, l-e, rcd testing ok on 0.5, 1X and 5X. Cant remember the figures, but tested fine.
Kitchen ring circuit n-e with washing machine and dishwash (both on d/p spurs) down to 150mohms with d/p switches on. 250mohms with d/p switches off.
Socket tests ok and no nipped neutrals anywhere. All other appliances test ok (not tested defrost on f/freezer yet)

Suggested he try micro next time with washing mach and dishwash switched off at wall, just to see if any difference.
Its still the same.

Cust wanting me to replace rcd, just in case.

Any suggestions.
 
if after ramp test there is still no solution why not put microwave on it own specifically labelled circuit and label socket MICROWAVE ONLY...on non rcd side obviously
So what happens if the micro wave is faulted and leaking excessively to earth you are now leaving the premises in a more dangerous condition so IMO that is a definite no. The RCD is there for a reason and trips for a good reason if not faulted. Remember the IET guidelines for leakage are .75mA Portable or hand held & 3.5 mA other class 1 equipment !
