Thread: Generator 3 phase, does anyone do this??

the shed circuits doing about 17 18Amps would that be fine

Good Morning Chris

I presume that you have had a look at the stuff on the Felder website. The videos are particularly interesting.

HAMMER woodworking machines Panel Saws Spindle Moulders Planers Clean-Air Dust Extractors

Precision equipment like Hammer and Felder would be dependent upon a reliable power supply, so hope you can find a good solution.

Looking at doing the same sort of thing, but looking for a much bigger unit than that. At the moment the biggest drain I need to supply is a 4KW car hoist motor, but on the woodshop side I will be looking toward a 3-5HP dusty and 2-3HP table saw or dusty and 3HP router etc. simultaneously. Don't know if you have a decent 240 single phase to shed, and just want something to power the beast, or you want to power the whole shedload of gear. I will have a single 15A mains into shed for battery chargers, lights, etc, but rely on genny for all bulk needs as I don't want to be running a genny to charge tool batteries.

The specs on the unit you linked are somewhat Chinese, it has a 20A 3 phase outlet, but cannot supply 20A. 8KVA is peak rating, and probably difficult to achieve, continuous rating is 5KVA, from a 6KW motor, they must have made some quantum improvement in efficiency over standard practice from the last 100 years. Personally think it would be hard to start a 4HP 3 phase motor with it, and it won't run a decent dusty and the saw. Single phase specs are 7 amps per phase, not really enough to start and run a 1.5HP motor on each phase.

Currently looking at a used 65KVA mobile backup unit from a factory closing down for my situation, overkill, but if it comes off, I can get it for under $2K with about 2000 hours run time over 20 years. Otherwise will be looking for a unit about 15KVA probably around $10K mark.

hey malb

it will just be the beast, dusty can just run of shed power lights are two fluro's.
i tested the power, it was sitting on 18amps.

I sold a Clearvue to a customer who ran it from a generator and the motor had to be repaired due to problems from the installation. I forget the details but it definitely needs to be done by a professional.
