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 !!!
If luminaires are divided across three phases using a common neutral, at least one device should be provided that simultaneously disconnects all line conductors.

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.

Yes but how the hell would I know the 3 circuits are all currently on separate phases I am not a clairvoyant, you only clarified that at #9. You said you didn't understand what I said so I was just explaining it.


How is clarifying what is exactly going on nit picking?
What a shambles of a site.

Everyone trying to nit pick and upstage everyone else.

why is everyone's cup in here half empty ...instead of half full ?

Please dont answer anymore.
I'll use another site if I need to.

The individual ccts WILL BE FED through a common 3 pole mcb.
Simple as that.

As recommended by the inspection snd testing guys who are in the real world!

Wonder how many replies have come from "millennial " electrician's who think they hsve discovered something new !


Please don't answer anymore because I will be
