I have just moved into a new property, which is supplied with all three phases, to what looks like a distinctly industrial board - no RCD, just breakers. I think it was rewired by a DIY sparks about 26 years ago!
The incomiong supply is PME, but no attempt has been made to do any form of load balancing, and a common neutral is used.
It seems that the phases have been used at random to supply different parts of the house. In one case, the downstairs lights are on the same phase as a pump providing for the water supply. It is a heavy load, and when the pump is running, the lights pulse.
The question is, if a heavy inductive load is causing voltage fluctuations on one phase, will the problem be resolved by connecting eg lights to a different phase?
Second question - can I replace the old three phase disribution board with individual distribution boards with RCDs to each phase? It will just make my wiring easier !
Any thoughts?
