Lynn, Go ahead with the 240 volt installation. Any amp that develops that much power should rightfully be powered from a 240 volt circuit. Although it may run on 120 volts, it will draw a significant ampunt of current and may even exceed the rating of a 120 volt household circuit - the full rated capacity for a 15 amp 120 volt circuit is 1800 watts, and 1300 watts is usually considered the maximum practical draw (ever notice that few hair dryers an toaster ovens draw more than 1300 watts!!!
While you are at it, consider using the next larger wire size than that required by NEC - the voltage drop at load will be less - a 15 amp circuit could use #14 wire, but I recommend using #12 (#10 for 20 amp) - of course if the run from the breaker panel is short, the voltage drop will be small even with the normally rated wire. 73, Don W3FPR > -----Original Message----- > > I assume that the new power amps will operate on 220 VAC.
