I did a consumer install today whilst testing the power shower feed I removed the spur to find two earth terminals, one with the normal earth symbol with the incoming earth connected the other with the load earth connected marked SE + the normal earth symbol. but there was no continuity between the two, hence no r1 r2 at the pump I did the obvious and connected them together to get the result I needed ???????????? Any info on the SE connection.
hi flats, are you saying: 1) there was no continuity between the pump CPC and spur or 2) there was no continuity between the spur and consumer unit?
I would expect the 'S E' to stand for either Safety Earth, or perhaps Second Earth? Which make is the FCU?
When I opened up the spur there was an incoming earth in one terminal and the out going earth was in the other, but between the two earths on the spur it was open circuit hence no r1 r2 at the pump
Supplementary earth? Perhaps designed to have somewhere to terminate unneeded earth cable in the case of double-insulated appliances, or choose to connect either or both to backbox lug? Just throwing ideas! Mr. HandyAndy - Really
I have been on a call out today and met our friend again same thing incoming earth in one terminal out going in another result outside socket no earth Bottom contact marked SE top E. the thin red wire is connected to the SE
I've always put both earth wires into the same hole when I've used those, (not the hole with the red wire in it) although I've never checked I've assumed the red wire is a functional earth for the rcd, maybe to operate the test function by earthing the neutral maybe?
I have come across this twice in the same week sen where both earths were used and the result was no valid earth at the end point. But at the end of the day it came down to lack of testing when job completed
I think that's a telecoms thing Eric? I've never seen cream earth conductors anywhere but on telecoms systems but I could well be wrong.
