In a 120/240 volt single phase service, a competent electrician tries to
balance the loads so that the two hot service entrance conductors will
carry equal current. If a 240 volt circuit is added, the balance, good
or bad, is not changed. In addition to what Martin says, the 240 volt
receptacle will carry 1/2 the current and will be less likely to heat
than a 120 volt receptacle. Go with 240 volts.
I left the electrical trade six years ago while senior service
technician at Amprite Electric in Nashville, TN.

The only reason, seems to me, is that on 240 V, you will draw half the
current, and you will experience less voltage droop and I2R power loss.
This may give you a little extra power on peaks and a little less
distortion. Maybe less dimming of lights on some circuits in your
house, too!
Let's see what others have to say.

Just added 240 volts to the shack.
I am wondering if rewiring my Centaur for 240 volts would change or
improve performance?
If so I would love an explanation of the theory behind any
improvement
or efficiency.
Thanks for any help.
