A 32,000 square foot office building d.32,000 VA
has 120 20-ampere, 120-volt duplex
receptacle outlets. What is the Note: 220.14(K) - use largest of either 1 VA per
branch circuit receptacle load? square foot or 180 VA per outlet.
Select one:
a.9,600 VA 180 VA × 120 = 21,600 VA32,000 ft2 × 1
b.21,600 VA
c.28,000 VA VA = 32,000 VA
d.32,000 VA
An AC charger with a single-phase a.Level 1
120-volt connection and 14-16
amperes of continuous current
output is classified as a ? charger.
Select one:
a.Level 1
b.Level 2
c.low-voltage
d.SAE standard
,According to Article 625, EVSE is c.the premises wiring system
equipment that has the specific
purpose of transferring energy from
? to the electric vehicle.
Select one:
a.a DC power source
b.a generator
c.the premises wiring system
d.the utility

ADA guidelines are useful when d.all of the above
planning an EVSE installation
because ? .
Select one:
a.there are no federal standards for
EVSE accessibility
b.they establish clear space around
equipment that allows for wheelchair
approach and access

d.all of the above
, Additional EVSEs are to be added to c.6
an existing 120/208-volt, 3-phase, 4-
wire, 600-ampere service with 220 220 A + (172 A × 1.25) = 435 A
amperes of non-continuous load and
172 amperes of continuous load. The 600 A - 435 A = 165 A
EVSEs each draw 32 amperes. How
many new EVSEs can be added to 165 A × 0.8 = 132 A left (due to EVSEs being
the service? (Note: Use 1.732 for the continuous loads)
square root of 3.)
Select one: (32 × 1.732) = 55.43
a.2
b.3 132 A / 55.43 = 2.38 or 2 per phase
c.6
d.9 Total = 6 EVSEs
Adequate site lighting increases the a.True
safety of an EVSE location.
Select one:
a.True
b.False

Select one:
a.62.5 kW / 500 VDC / 125 A
b.350 kW / 480 VDC / 80 A
c.400 kW / 1,000 VDC / 400 A
d.1 MW / 2,200 VDC / 800 A
