Having "acquired a self start 20KVA 3 phase generator I was having
thoughts of running the bungalow mains off one phase in case of power
outage (commoner than I expected here in the sticks, we lost some rare
eggs that were hatching TWICE this year,,,). Does anyone have links to
how an auto start and switching arrangement could be contructed? I assume
I can isolate the boards electric input on "our" side of the boards fuse
and meter, and have a switching arrangement to bring on the gennie. Needs
careful failsafe handling, any ideas? Thanks
That's the way to go. I would just switch the house supply so you can
choose which main to use, the generator or your electricity board, that's
the safest and most bomb-proof solution. It'll mean a manual changeover in
the house, rather than an automatic one. That's the arrangment we have, it
Try to evenly load the demand for each of the three phases though.
Just keep the governor on the generator serviced - With an unexpected 550V
output I managed to melt every transformer in our house last winter when
ours failed. Baby alarms, phone chargers, even the microwave - all kaput!
Still, it was an education to see just how bright a 60w bulb can go before
it gives up the ghost!

Depending on how much load you put on that single phase the alternator
may start to object to being out of balance electrically. Remember
that that 20KVA is almost certainly across all three phases so each
one is probably only 6KVA...
Does this "aquired" gene come with any switch gear? It may already
have the required bits, though things that are "aquired" are generaly
old, (beyond commercial economic repair) and thus using said switch
gear might not be a good idea. B-)
