Guys, I have a phase converter - installed it myself, and it's really not a big deal. One thing that I like about them is that a lot of really solid used equipment is 3 phase, and being set up for it allows you to take advantage of some solid, older high quality iron.
Wiring is actually smaller for 3 phase equipment - versus single phase, because you are dividing the amperage required for equivalent horsepower across three legs, instead of two. Thus, a 7hp 3 phase motor may only require 10 guage wiring, yet a 7hp single phase would require 6 guage wire.
If you ever decide to install a phase converter, I would recommend that you wire it into a 3 phase load center, instead of the actual piece of equipment that you need to power. That way if/when you require additional equipment you simply need to install a new run to the load center and you're done, versus moving the converter around or having to purchase additional coverters.
The wiring for the converters is very simple and straightforward. Anyone that has a good understanding of electrical wiring can handle it. It does cost you a bit more on the power bill though, because you lose some efficiency in the conversion process. However, if you can save significantly on the cost of used 3 phase equipment, I think that the hardware savings will outweigh the increased utility costs.
Jerry - thanks for sharing this info. Unless someone else on this site really wants this machine, I think that I'll bid on it. However, if someone else really wants it let me know and I won't bid (so as not to drive the price up). Let me know by a PM or e-mail to
scotttsmith@bellsouth.net Thanks.
