An existing 400-ampere, 120/208-volt, 3-phase, 4-wire service has 30 kilovoltamperes of
noncontinuous load and 58 kilovolt-amperes of continuous load. How much more continuous
load can be added to the service? (Note: Use 1.732 for the square root of 3.) Select one:
a.33,281.92 VA
b.41,436 VA
c.102.5 kVA
d.143.93 kVA - Correct Answer > a.33,281.92 VA
Note: 30 kVA + (58 kVA × 1.25) = 102.5 kVA
400 A × 208 V × 1.732 = 144,102.4 VA
Remaining VA available prior to continuous load correction = 41,602.4 VA
41,602 VA × 0.8 = 33,281.92 VA
A Level II EVSE with a rating of 32 amperes at 208 volts is installed. What is the minimum
size copper equipment grounding conductor required to serve the
installation?
Select one:
,a.10 AWG
b.8 AWG
c.6 AWG
d.4 AWG - Correct Answer > a.10 AWG
Note: Section 250.122 - the EVSE will be served by a 40A OCPD; therefore, the minimum size
equipment ground will be 10 AWG.
