what is the minimum size grounded conductor for a dwelling with a load of 50428VA 240V?

Homework Answers

Answer #1

current = 210.12 amper

So, I ASSUMED YOU ARE FROM U.S.

according to NEC CHART (TABLE 250-95)

WE USE 4 AWG FOR COPPER AND 2 AWG FOR ALUMINIUM.[according to the table this size of wire is saffiecient for maximum 300 amper]
