Hi guy's
had a tricky one today at a house. We have fitted 2 x inverter air conditioning systems.
The sparks fitted a consumer unit and two 32a c/b with a 30ma rcd. Running 6mm SWA to the outdoor isolators.
However when we switched on the c/b one worked but one tripped the RCD. I spoke to the manufacturer who said "We do not recommend RCD's for inverter systems as they leak down the neutral and trip."
We know it's the outdoor unit which is causing the trip by isolating the mains and interconnect etc. However the trip is instant as the RCD won't hold..
So the sparks was very worried and not at all happy about removing the RCD from the C/U and fitting a std switch. But without the swap the second one won't run
How would you arrange the supply to satisfy the regs and the air con ?
Cheers
