Could someone please help me or point me in the right direction.
I can't quite understand the neutral.
Its the return path after the load (do correct if I'm wrong)
Its at 0 volts, but if a break in the neutral happens, the neutral will rise to mains voltage, the circuit has become a series circuit, and anything that comes into contact with both ends of the broken neutral will become the new load
Single phase
An RCD would see the current come in though the line conductor, it would then power its load and leave by the neutral conductor.
If 10 amps came in, 10 would leave, and the RCD is happy, if only 9 left, it would trip.
This is where I start to get confused.
So 230 volts is pushing the current to the 10A load,
The load takes the 10A and returns on the neutral.
How come its still 10 amps on the neutral, with 0 volts?
The neutral is at 0 volts, so no push, but I know the 'power' really wants to get back to the start, but what is pushing it.
3 phase
Clamp on the neutral
Brown phase switched on, 50A say.
so 50 Amps on neutral
Black phase switched on 50A
How many amps through the neutral?
Grey 50A
Amps through the neutral?
The three phases all being 50A, would they cancel each other out, so the neutral return would be around zero? but what if only one phase used?
Thanks for anybody who could get through that, and be inclined to reply.
