Three phase vs single phase

[Lourens.dL]

Just a quick question, why MUST the electrician be registered with ECA? Surely if he is registered with Dept. of Labour as contractor it is enough?

But back to OP's problem. You could put all you essential loads you want to run on solar power on the one phase and non essential loads like geyser / underfloor heating on the other phases. Essential loads could be lights and important plugs.

However, it normally is possible to wire a 3phase switch-over to be fed with one alternative supply phase. Obviously the proper protection must be in place.

Obviously a proper inspection of your DB will determine the best solution.

Good morning Lourens - from my perspective there is no reason why the person needs to be a member of the ECA, all I want is an experienced, knowledgeable and reliable person who can sort all this out for me. I cannot at the moment back-up the lights from my solar system because the stair lights (which have 2 switches - one downstairs and the other upstairs) are wired in a "interesting" fashion with the live coming from the downstairs DB and the neutral upstairs - would need to be sorted out before I can back up the lights. The solar backup is only connected to the upstairs plugs as all three phases go down to the bottom DB and I cannot connect to individual loads.
Like I said - Need someone with extensive experience and who is old-school enough to still take pride in his work (and who is looking for an interesting challenge!) to spend some time to sort out this mess
