EVITP FINAL EXAM
Calculate the voltage drop on a single-phase circuit with 32 amperes of load, a distance of 320
feet from the load to the panelboard, and served by 8 AWG copper THHN conductors.
Select one:
a.13 V
b.14 V
c.15 V
d.16 V
d.16 V
2KIL / A = VD(2) × 12.9 × 32A × 320' / 16,510 cmil = 16 V
Calculate the following correct copper conductor size so that the branch circuit has a
maximum voltage drop of 2%. The load on the circuit is 32 amperes, the distance from the
load to the panelboard is 400 feet, and the circuit is 208 volts, single-phase.

Three single-phase Level II EVSE are distributed equally on a 3-phase, 4-wire system and each
EVSE draws 24 amperes. What is the line current on each phase? (Note: Use 1.732 for the
square root of 3.)
Select one:
a.24 A
b.41.56 A
c.52.6 A
d.64.33 A
b.41.56 A
24 A × 1.732 = 41.56 A per phase
Two Level II EVSE circuits are installed in the same PVC conduit. Each EVSE is served by a 40-
ampere circuit at 240 volts with an EGC run along with the circuits. What size copper EGC is
required for this installation?
Select one:
a.10 AWG
b.8 AWG
c.6 AWG
d.4 AWG
a.10 AWG
Note: T250.122 - 40A Circuit = 10 AWG CU equipment ground
Nine Level II EVSEs are installed on a 3-phase, 4-wire 120/208-volt system. Each EVSE is
208/240 volts, single-phase and rated at 24 amperes. What is the minimum ampacity of the
copper feeder conductors required to serve the installation?

a.90 A
b.156 A
c.167 A
d.180 A
b.156 A
-24 A × 1.25 = 30 A required for each EVSE3
-units on each phase = 30 A × 3 = 90 A
-Line current needed to find feeder size: 90 A × 1.732 = 156 A per line needed
-156 A = 2/0 Copper
What is the general lighting load of a store with an area of 12,000 square feet?
a.12,000 VA
b.36,000 VA
c.45,000 VA
d.48,000 VA
b.36,000 VA
12,000 ft2× 3 VA per ft2 = 36,000 VA per Table 220.12
Continuous factors are not needed as actual lighting load is all that is requested. Correction
factors will apply when sizing the branch circuit OCPD and conductors, which is beyond the
question scope.
A 32,000 square foot office building has 120 20-ampere, 120-volt duplex receptacle outlets.
What is the branch circuit receptacle load?
Select one:
a.9,600 VA
b.21,600 VA
