True, false, or somewhat true and/or false?
Multiply each side's voltage x current and compare the results.True, false, or somewhat true and/or false?

Exactamundo! :happyyes:So I'd have 43.3A?
The sub panel is a 100A 120/208V 4 wire. I am trying to determine how many available amps at 480V I'd have. I did some research and it said that I'd have one-third of the current available on the secondary side. But didn't know how they came up with that figure, so...
P = 208V (E) x 100A (i)
P = 20,800
20,800 = 480V (E) x X (I)
I = 20,800 (P) / 480V (E)
I = 43.333
So I'd have 43.3A?
I rest my case.Now I know how to calculate it.
VA, not WMultiply each side's voltage x current and compare the results.
Hint: P = E x I
(W = V x A)
We don't like to simply answer questions like this; we want you to figure it out.

One lesson at a time. I used what I believed OP to be familiar with.VA, not W
Actually, you don't need either.One lesson at a time. I used what I believed OP to be familiar with.
