Correct. Just as a light is driven by a ballast. The load presented to the brach circuit is not the bulb.

I think where the confusion is here is that input and output voltages are not the same. But we dont care what the output voltage is for branch demand calcs.

For current usage calculations, the nominal input voltage is always the divisor for cicruit loading calculations.

Naw, Ian or Andrew would be bored half asleep. Intro stuff.

Fwiw, most electricians wouldn't give a sniff about this sort of thing. But it is really neat to know the electrical theory behind what makes your pants shake in the pods emerge scene in war of the worlds!

I had a meter on mine for a few days and after watching a few movies at pretty good volume it only registered just over 1 amp draw or about 130 watts.

I didin't take chance, my EP500v3 is connected on a dedicated 15amp circuit. I have no problem of load, humm or noise on this circuit.

if you have room on your electrical distribution panel, i suggest your to do the same.

i drive my ep500 on a share circuit a while ago i the result was ok, my circuit at that moment wasn't overload.
