Is the calculated load on a 150watt HPS just a straight 150W? At 120v volts it would be .8 amps?

120/208/240/277 ballasts have operating currents of 1.8/1/.9/.8 respectively,,this current is what is used for circuit loading,the socket voltage oft times does not vary even tho the wattage may.............480V is .4 amps if you need that.

And, don't forget to cap those other voltage taps. Each puts out its labeled voltage when any one is supplied at its voltage. The primary is an auto-transformer.
