grade level and located not more than _____ft. above grade shall be installed at the
front and back of the dwelling. - ANSWER-6.5
At least one 125-volt, single phase, 15- or 20-ampere-rated receptacle outlet shall be

Load Calculations - ANSWER-idk, mang
Service drop conductors shall have a vertical clearance of not less than
_____________ feet above the roof surface - ANSWER-8
Equipment grounding conductor provisions - ANSWER-Table 250.122 and 250.102
What is the service demand load in kW for an apartment complex containing ten each of
the following. 15 kW ranges, 13 kW ranges, 11 kW ranges, and 9 kW ranges. the
service is single phase. - ANSWER-Table 220.55
First find the average kW using 12 kW for any range rated less than 12 kW
(10 x 15) + (10 x 13) + (10 x 12) + (10 x 12) = 150 + 130 + 120 + 120 = 520 kW
[Note that we used 12 kW for the 11kW and the 9 kW]
520 kW / 40 ranges = 13 kW average range size.
Column C shows 15kw + 40 (number of ranges) = 55 kW
This 55kW must be increased by 5% for each kW above 12 the average size is.
55 kW x 1.05 = 57.75 kW demand load.
In_________________, remote, central, or automatic control of lighting shall be
permitted - ANSWER-hallways, staircases, and outdoor entrances
A grounded circuit conductor shall be permitted to ground non-current carrying metal
parts of equipment on the ______________ side of the ac service disconnecting means
- ANSWER-supply
Equipment grounding conductors, where installed, shall be increased in size
proportionately according to________________ - ANSWER-Circular mil area of the
ungrounded conductors
An intersystem bonding termination shall consist of a set of terminals with the capacity
for connection of not less than ________ intersystem bonding conductors. - ANSWER-3
