3 phase converter

Hello Guest:
There should be a tag on the rotary converters 5 hp motor indicating full load amps, a true 5 hp single phase motor will be in the neighborhood of 28 full load amps at 240 V. For this I would recommend a 40 amp HVAC rated circuit breaker, and number 8 wire to your outlet.

Hopefully you are talking about a electric dryer outlet , in which case both the wire and the circuit breaker should be large enough. If you're trying to do a quick conversion on a standard 110 outlet you've probably got number 14 or number 12 wire which is far too small to be protected by a 40 amp circuit breaker, so this is the case you will have to pull new wire to that outlet.

Since you are only running a 2 hp mill you might be able to get away with a 30 amp circuit, so if you find you for some reason you have number 10 wire to the outlet you might want to try a 30 amp breaker if it would be difficult to get new wire to the outlet.

The important thing here is to remember not to exceed the amp rating of the wire, if the circuit breaker is too large for the wire size you will have the ultimate smoke tests if there is a problem.

If the circuit breaker is too small for the motor the worst that can happen is it will trip. I've included a link that has some information that will be useful to you.

Good luck.

You need to hire a licensed electrician.

The changes you are suggesting will most likely void your homeowners fire insurance policy if things should go awry. Just sayin.

Size the breaker for the conductors, period.

The 240V dryer circuit should be already sized correctly and should work fine as long as the conductors you plug into it are the same size or larger. The inverter rating is inconsequential as long as the conductors are protected. If it tries to draw 5hp worth of amps to a 2hp motor, you have problems--If wired properly it won't.

If you draw more amps than the dryer circuit can deliver, then you will trip the breaker--No harm. Don't upsize the breaker.

2hp--I would guess that the FLA on single phase motor would be within the capacity of that circuit--try it, but use caution.

should i put another breaker before it goes to my mill ?

Somehow I missed the second part of your question, I agree with a previous poster, as long as the equipment does not run unattended,and provided it is not hardwired. , if it is hardwired the ampacit of the wire must be matched to the circuit breaker.

Whatever you do not size a circuit breaker larger than the ampacit of the wire. I have included A link to another chart that may be easier to read. As previously mentioned if you do not understand how to identify your existing wire, or feel uncomfortable doing the job,: call a electrician it's cheap insurance.

I reread the original post and I am not sure about what it is that you have, now.

Hello Kilgore Trout: you said

"I reread the original post and I am not sure about what it is that you have, now."

I'm not quite sure whether replying to me are the original poster, sometimes my post end up in the wrong place.

If you're replying to me, my concern was that the correct size wire be run all the way to the equipment in a permanent installation.

If you're referring to the original post, I'm not quite sure what outlet he's converting either. I'm assuming he's in the United States by the voltages he's referring to, but maybe he's in a European country.

If so 220 V would be available in the washer outlet, and the wiring definitely would not handle a 5 hp motor.

Nope--I concur about the conductor size/breaker size being paramount.

I originally thought he was driving a 2hp motor with a 5hp rated drive--No problem as long as the breakers/wire are proper--I'm not sure what it is, now. You seem to be giving good advice so I will stick my nose in later if I get time.

Trouble with some guests is they never elaborate after questions.

Kind Regards--K T
