Which of the following is the MINIMUM size grounding electrode
conductor required for this service, assuming copper conductors?
A) #6 AWG
B) #4 AWG
C) #2 AWG
D) #1/0 AWG
, 4|P a g e
Rationale: According to NEC Table 250.66, for a 400-ampere service,
the minimum size grounding electrode conductor for copper is #2
AWG. This applies to services up to 400 amperes with copper
conductors.
8. An inspector is examining the grounding electrode system at a new
commercial building. The building has a concrete-encased electrode
(Ufer ground) installed in the footing. Which of the following is a
requirement for this electrode to be acceptable?

B) The electrode must be at least 20 feet of #4 or larger steel
reinforcing bar
C) The electrode must be at least 10 feet of copper-clad steel rod
D) The electrode must be at least 20 feet of bare copper wire
Rationale: A concrete-encased electrode (Ufer ground) must consist of
at least 20 feet of bare copper wire or steel reinforcing bar (#4 or
larger) located within and near the bottom of the concrete footing, as
per NEC 250.52(A)(3).
9. A commercial building has a 600-ampere, 208Y/120-volt, three-phase

conductors required for this service, assuming 75°C terminals?
A) 300 kcmil
B) 400 kcmil
C) 500 kcmil
D) 600 kcmil
Rationale: According to NEC Table 310.15(B)(16), a 600-ampere
service using aluminum conductors at 75°C requires 500 kcmil
conductors, which have an ampacity of 500 amperes (or 380 amperes
for 400 kcmil). The 500 kcmil is needed for 600 amps.
