As some pointed out the heaters will be cooler than could be since,

 Power is proportional to the square of the voltage.
  Power (Wattage) will be 208^2 / 240^2 of it's 240v rated value.

Most heating elements have some kind of thermostat and have an extra
allowance of heat anyway. Designers keep this voltage thing in mind.

Glad it works out for you.


I finally (yesterday) got the vacuum press connected and everything is AOK
:-D  The pump is 1/3 HP single phase 120 VAC so that was no problem.  The
elements seem to heat up at the same rate they did before.  I did not check
the voltage in my other unit but there is very little doubt that it was also
three-phase so it was probably running from 208 volts before.  Now for the
neon signs....

Thanks everyone for all the help!

P.S. I tried to post this from my laptop and it wouldn't send so I hope this
isn't a duplicate.
