Done an EICR yday on an old house and all ok apart from 2 issues.. 1) 32A cooker circuit had high resistance pec continuity (over2kohms) ALTHO it did buzz out on my voltage probes. Hence not able to get a Zs reading and no rcd tripping. The dual rcd consumer unit was fitted 10 yrs ago and those test readings all available and fine. Kitchen was refitted 3 yrs ago and no docs available so they extended original cooker cable prob from the switch which is now tiled over somewhere. .. I've put in an earth wire link from an immediately adjacent rfc socket into the cooker switch and this solves this problem. Question .. is this ok as a permanent solution if i label up what ive done? 2) lowish IR readings 1.75M L-E and N-E on light circuits and one rfc but possibly in hindsight due to some bulbs, fan and appliances still plugged in. Could this account for it?
