Departures from bs7671, certification.

[odawire]

Hi, I have always made sure my installs have no departures from bs7671 but I'm doing a ccu change next week and have done some preliminary testing and the heating circuit (boiler and heating controls) has low IR readings, had a look in all obvious places and cant find any problems, had trouble breaking the circuit up as its a bit messy, client has just decorated so he doesn't want any damage to the house, seeing as its all fixed equipment (I'm unsure on the cable routes but id guess its buried less than 50mm at some point) is it acceptable to leave this circuit unprotected and note it on the departures section? all the earthing/bonding is mustard. Any experience on this would be appreciated, thanks.

but you will find lots of peeps with forthright views who will defend them vigorously.

Cheers

Yea, I guess that's the point of the forum eh?

Ok, so apart from the disagreements on what's right and wrong and what certificates are needed, which has definitely been dealt with, I think everyone has missed an important point,

Hi, should have explained, I have a rig I made up I use sometimes, its basically an rcd adaptor that I wire into and plug into a socket, when I did this it tripped

firstly, you've done IR tests and you know that whatever is wrong with the circuit, the readings calculate out to an acceptable value, so end of you should be happy to connect this to an Rcd. but you are relying on a home brewed tester to test whether its safe to connect to Rcd, I would look here for your answer. Your calibrated tester is telling you everything you need to know

Unless the rig is picking up something he's missed in testing....

Its not something I use a lot, its just been handy a few times
