1. 208v Air Compressors (score: 1)

My choices in air compressors at my new home are limited by the fact that we have 208v 1-phase power. Had I known ahead of time that this would limit my choices, I would have run 3-phase to the locat

I can't tell you anything about the brands you mentioned, but the electric motor manufacturers in North America make motors rated at 208/230 volts. That means they work on just about any supply volt

I would hope that you really have 220/230 in your shop. 208 is actually found as the odd leg to neutral on a three-phase system, with 110/120 to neutral on the other two legs (and 220/230 from phase

I think 208 is any hot to any other hot in the typical 3-phase voltages, with 110 being any hot to ground. All three hots are equal. 220/230/240 is the nominal value for hot to hot in a single phase

Not at all. I've done a _lot_ of three-phase work. The only time you will find 208 phase-to-phase is in a "208-wye-120" system, where there is indeed three phases of 208 phase-to-phase, but also thre

I'm not sure I understand this. If the phase to phase are all balanced (equal), than shouldn't all the phase to neutrals be balanced also? Tim Mullen /// /// shop-talk@autox.team.net mailing list ///

How can this be? The two phases coming into the normal house should be 180 degrees out of phase. But in a three phase system the phases need to be 120 degree out of phase (relative to the adjascent p

Hmmmm. I'll try some ASCII art. C / \ / \ / \ / \ / \ / \ / \ / \ A--n--B Phases A and B are the 120 legs, n is neutral, C is the third phase. The angle between A and B is 180 degrees, while the angl

Don't know whether this will help anyone else - but what I understand from explanation is that the three phases are equal and balanced but the neutral is not "at the center". Makes sense to my mechan
