they should have a test switch. note: MCB is allowed as a test switch, but best to have a seperate switch (which allows the main lights to still function whilst emergencies are on test)I'm ok to run it straight from breaker in CU then aren't I? Don't have to be able to switch it on/off manually...?
using MCB, you loose all lighting. if the em fitting has its own switch, only the em light looses power (and so lights up). other lights will workNot sure what you mean here Andy Blushing
If I do the above, I am creating a "new circuit" aren't I - even if it's going in with another circuit, so this means I have to provide an EIC doesn't it???I'm ok to run it straight from breaker in CU then aren't I? Don't have to be able to switch it on/off manually...?
you can take a spur (/branch) from anywhere, including the MCBIf I do the above, I am creating a "new circuit" aren't I - even if it's going in with another circuit, so this means I have to provide an EIC doesn't it???Would someone mind confirming this for me, so I don't waste time doing one if it can go on a MWC
Thanks.
note the highest reading, which is most likely to be the existing part of the circuitYes, have just thought about it and in agreement. So this means when doing R1, R2 test, Zs etc, I have to include entire circuit then don't I, not just what I've added?
Hi BattyAndy that can't be right it just does not make sense. I think we are back to adding a spur to a ring main again which is wrong as far as I am concearned.Batty
what doesnt make sense? how can you argue that taking a spur from a MCB is wrong but its OK to take it from a socket?Andy that can't be right it just does not make sense. I think we are back to adding a spur to a ring main again which is wrong as far as I am concearned.Batty
