What is the minimum copper THHN feeder size for 12 EVSEs
rated at 24 amperes on a 3-phase, 4-wire, 120/208-volt
system, assuming four EVSE per phase? (Note: Use 1.732 for
the square root of 3.) Select one:
a.250
kcmil
b.350
kcmil
c.4/0
AWG
d.2/0 AWG - ANSWER-c.4/0
AWG
24 A × 1.25 = 30 A
There will be four per phase.
30 A × 4 = 120 A per phase
Line current is 120 A × 1.732 = 208 A feeder = 4/0 Copper
