If luminaires are divided across three phases using a common neutral, at least one device should be provided that simultaneously disconnects all line conductors.Doesn't ANY 3pole MCB go Cross 3 separate phases ?
eg a three phase motor protected by a 3ph mcb has 3 separate phases going across it ?
I used this forum once before and all I got was nit picking....individuals finding fault with everything.
If....if....if....
If my auntie would have had b****ocks she would have been my uncle .!!!
I thought I'd ask a reasonable question...can I feed the individual ccts through a 3 pole mcb.
Please....yes or no !!!
TP MCB would ensure that all lines associated with that neutral were isolated together.
Don't switch the neutral (assuming TN supply) as it's always worth keeping it as reliable as possible.
