By wiring the two elements in series across any two lines.How would a 2-wire, 240VAC element be wired to work on 480, 3P power?
So one wire terminated to L1, and the other terminated to L2, of the 480 3P power?By wiring the two elements in series across any two lines.
ONLY IF THEY ARE THE SAME RATING OF HEATER.Huh? that is not "series".
One lead from heater A to L1
One lead from heater B to L2
The other leads from A and B together.

Ok. I think that is how they have it wired now. Wired that way, actual voltage to the heater element would be ?? 240V since its only one leg, correct? What if there was only one heater? Where would that lead go to, or would it just not terminate anywhere and just wire nutted?Huh? that is not "series".

Each would see 240 volts.Ok. I think that is how they have it wired now. Wired that way, actual voltage to the heater element would be ??
Definitely, although I kind of expected that in this case (doesn't hurt to qualify that).ONLY IF THEY ARE THE SAME RATING OF HEATER.
Take a look at the rules for series and parallel resistors.Wired that way, actual voltage to the heater element would be ??
Will do. Thanks. Right, heater is just a resistor.Definitely, although I kind of expected that in this case (doesn't hurt to qualify that).
