I've been called to a job for a friend as his swimming pool pump keep tripping the RCD, it took me a while to work out how the other electrician had wired it but of what I see, it's a bit of a mess. I'll do my best to explain for the pool I can see 3 MCB's used 1st is a 6A type b in to a time clock in 1.5mm2 then that goes into a contactor then there is a 32A type c in 6mm2 that goes into the contactor then SWA to the pool. Then the last one is a 10A type c in 1.5mm2 that goes to a switch then in SWA to the pool to the plug where the pump plugs into, this is when the RCD trips. I've tested the cables and they are, R1-R2 1.32ohms insulation resistance is all around 100Mohms. Ze is 0.19ohms Zs is 1.21ohms PFC is 1.22KA and the RCD trips within the permitted times, the pump is PSH mini.2 50m 0.37KW. I've never worked with swimming pools before it's a bit out my comfit zone I'm just trying to help a friend. Also the pump works fine for hours when pugged into another RCD protected circuit.

thats the problem then isn't it? the black leather on the pump is causing it to overheat and trip the breaker.:coolgleamA:

Simon,
just admit one thing. You are not competent to be working on any installation, never mind a swimming pool.


Your record on here hardly sparkles does it?

Find something else to do, Joe Public deserves that.
