"bump" for Gav..
The data plate on the no name generator says 3 Phase 70kva
We’ve just reconfigured it to Single Phase, is there a way of calculating its new capacity???? when the data plate doesn’t state 1P capacity.
Gotta love farm life…….that’s what we refer to the place we work at…..a bit more to tie story
The main generator dropped a cylinder so we’ve been running off the 27kva back up which is annoying the guests at the powered sites as they are not allowed to use A/C, jugs, hot places etc.
Sooooo we’ve dug out the retired 3phase 70kva that was recently replaced to be the new gennie over the hill.
Reconfigured the windings, removed some wires than with google (my input to the day as I was battling hydraulic hoses on a Moxy and servicing the bore pump) help reprogramed from 3 phase 4 wire to 1 phase 2 wires (that has us scratching our heads but all is good)
Tomoz, we’ll it’s my Saturday, the boss will pull the failed gennie out, drop new gennie in, wired it all up, hopefully happy campers.

Thanks Pete - I didn't see the thread until you bumped it.
Depends on the alternator but between 50 and 65% of its 3 phase capacity, and depending on how they reconfigured it as there are a couple of ways of doing this as well and it also depends on if the alternator is a 12 wire or 6 wire unit. If it was 70KVA 3 phase - that's around 97 amps per phase, I'd say you'd be somewhere in the vicinity of 140 to 190 amps single phase - crap loads for most things! Not sure what single phase loads you have that are that large but you shouldn't have an issue. Whoever converted it should have put a new breaker in it I would have thought - it probably had a 100 amp MCB in it, did they change this at all?
What brand and model is the alternator - I could work it our more accurately with that data.
All this is based on the engine being able to drive the 70KVA alternator to full load as well - some machines had over sized alternators deliberately so you couldn't hurt them - the engine would run out of power first - what engine/HP/KW is it?

Boss says it’s a Chinese Perkins with 25,000 hrs
Interesting thing is it has no oil leaks.
Cool, I’d say 50% of its 3 phase rating in that case so around 147 amps max single phase.
