    Are you sure these are 15 KW strips? How about 1.5 KW strips?

    Power (watts) = volts * amps.

    15000 watts = 120 volts * A
    15000/120 = A
    125 amps = A (kind of high, I think).

    If it's a 240 volt circuit
    15000/240 = 62.5 amps

    If it were a 1.5 kw circuit
    1500 / 120 = 12.5 amps
    1500 / 240 = 6.25 amps

    If it's a 1.5 kw strip, and it's pulling 21 amps, it's probably faulty. It's too high regardless of the voltage being applied.

    If you have a 15 kw heat package with three 5 kw strips at about 240v, 21 amps is about average (per strip).

    5000 watts / 240 volts = 20.8 amps. That makes sense.
