Yea I'm wanting to know why the earth has no split in it?

I am just curious that's all, anybody know why?

Sorry can you answer it?

Sorry can you answer it?

Why does the neutral bar have to Be split for each rcd and there is One earth bar for everything?? And do you connect the earth nearest the main switch to earth terminal 1?

and also if the same cable was connected to each other L1-N1 and L2-N2 that is double the distance that has to measured yea?

ok but why does the cores not be at equal distance if your connecting the same live and neutral of the same cable to each other and when u cross them over on each other they are at equal distance?

Hello, im just reading a book just now and there is something ive just read about the ring final continuity test i dont understand, say when u cross the live to the neutral of the same cable and not the opposite neutral the books says " that the resistance will start to go higher as u...

is the purpose of that drawing, when the emergency lights are put into test mode, the LED will be OFF, wouldnt it be on with the supply off the mains supply to the switch going across the link to the LED.?? or how does it work?

thats ok i was only enqurying as to what might have to be done, but i was going to get the materials for the job ya know, so is 4mm2 cable and 2 fused spurs ok for the job with 2x 20amp breakers yea?? Thanks.

why wouldnt you use just one twin socket? is it ok to use a fused spur with a 13amp fuse in it? as the heaters have no plugs.

hello, what would be best for wiring 2x 3kw heaters would it be better to wire a 20amp radial then use a fused spur for the heaters then? Thanks.

why does a 20 amp breaker allow 30amp to flow through doesnt that defeat the purpose of a 20amp mcb?? and why is the cable that is choosen its current carrying capacity bigger than the mcb current capacity?

so no matter what the calculated amps is for a circuit, e.g 18amps, there is always gonna be more than that under fault conditions yea? is that why the nearest breaker is used to prevent it from getting to extreme amps?? Thanks.

Hello, Just a quick question that i was thinking about, Why is a mcb chosen higher than the current taking in a circuit say the circuit was pulling 18amps you would a 20amp breaker wouldnt this 20amp breaker not be to high to trip because the circuit is pulling 18amps which less than...

http://www.gbbulbs.co.uk/acatalog/Philips_S2__ST151__4w-22w_Series_.html what does it mean by in series is that when the two lamps are connected together and this starter will allow them to work like that ok? and it will also work for single lamp use too yea?

and when the starter is located is it a normal starter or what is it?

why cant you connect the socket to something more than 32amps?? if the sockets internals are rated at 13amps only then???

why are sockets rated at 13amps then and protected by a 32amp breaker?

i thought the 4pins lamps was only the emegency lamps?? is that wrong then?
