The downlight should be earther now it has 230v going to it.
Having said that, some of the ridiculously flimsy fortuoutous connection to earth on some GU10 downlights renders it, in my opinion, almost pointless anyway!
What reg is that please?
I cant see a situation where alarms would be powered from diferent circuits yet have a common interlink wire. Surely if one has gone to the trouble of running in a separate interlink wire to each smoke they may as well have run a 3c&e to each fitting, meaning that...
Yep either a different switch or cut out the existing back box and sink a 35mm deep box in, but there will probably be some making good to do afterwards!
Agree with the above. And also the socket lead adapters in my experience go high resistance quite often too.
If you don't do the fig 8 test for R1R2 then you won't pick up any NE reversals if the circuit isn't RCD protected (assuming that the R1RN test isn't carried out as a matter of course).
Actually, Ive just checked the Icon instructions for the 230v models and it states this on page 2:
"The iCON Fan has an IP X4 rating housing and is suitable for mounting in Zone 1 or 2 in bathrooms, toilets, kitchens, utility rooms and inside shower cubicles as defined in Section 701...
Yes John, thank you. That's pretty much what I was trying to say. I'm afraid I don't seem to be able to go into enough depth or articulate myself properly when posting!
I too would always advocate tracing a fault and rectifying and 9.5 times out of 10 the customer is happy for this to happen...
