1. During review of a proposed 2,400-square-foot single-family
dwelling, the electrical plans indicate a 200-amp, 120/240-volt, single-
phase service. The calculated general lighting load is 7,200 VA, small-
appliance circuits total 3,000 VA, and the laundry circuit is 1,500 VA.
Which principle should the plans examiner apply first when evaluating
the dwelling's service load?
A. Add every connected load at 100% regardless of demand factors
B. Apply the dwelling-unit demand calculation methodology permitted
by the adopted electrical code
C. Use only the general lighting load because appliances are separately
protected
D. Size the service according to the number of branch circuits shown
Answer: B.
Rationale: A residential service calculation is not ordinarily based
simply on adding every connected load at 100%. Dwelling-unit
calculations generally permit specified demand factors and allowances
for certain loads. A plans examiner should verify that the designer has
correctly identified applicable loads, applied permitted demand factors,
and then selected service conductors and overcurrent protection
accordingly.

,2. A residential electrical plan shows two 20-amp small-appliance
branch circuits serving the kitchen countertop receptacles. The designer
has connected the refrigerator receptacle to one of these circuits. Which
statement is most appropriate for plan review?
A. The refrigerator must always have a dedicated 30-amp circuit
B. The refrigerator can never be supplied from a small-appliance circuit
C. The plans examiner should determine whether the adopted code
permits the refrigerator to be supplied from the small-appliance branch
circuit under the particular installation
D. The refrigerator must be connected to the lighting circuit
Answer: C.
Rationale: Kitchen small-appliance branch-circuit requirements are
specific, and certain outlets or equipment may be permitted or
excluded depending on the applicable code provisions and
configuration. A plans examiner should not automatically reject the
refrigerator solely because it is connected to a small-appliance circuit;
the complete circuit arrangement and adopted code must be evaluated.
3. A dwelling plan identifies a 240-volt electric range rated at 12 kW.
The service calculation includes the entire 12 kW at 100% without
considering any applicable household cooking-appliance demand
provisions. What is the most appropriate review comment?
A. The range must be connected to a 15-amp circuit
B. The designer should evaluate the applicable demand calculation
permitted for household cooking equipment
C. The range load should be excluded completely
D. The range must be calculated as a continuous load
Answer: B.
2
,Rationale: Household cooking equipment can be subject to specific
demand calculation provisions rather than automatically being
included at its full nameplate rating in every residential service
calculation. The plans examiner should verify the number of
appliances, ratings, applicable demand table or methodology, and
resulting feeder/service load.
4. A residential plan shows a 125-amp feeder supplying a detached
dwelling structure. The feeder consists of two ungrounded conductors,
one grounded conductor, and an equipment grounding conductor. Which
issue is most important when reviewing the feeder at the detached
structure?
A. The equipment grounding conductor should be omitted
B. The grounded conductor and equipment grounding conductor should
be evaluated for proper separation and bonding at the separate structure
C. The grounded conductor must be smaller than the equipment
grounding conductor
D. The feeder must always contain three ungrounded conductors
Answer: B.
Rationale: A feeder supplying a separate building generally requires
careful review of the grounded conductor, equipment grounding
conductor, grounding electrode system, and bonding arrangement.
The downstream structure normally requires separation of grounded
and equipment grounding functions, with the exact requirements
determined by the adopted code and installation conditions.
5. A plans examiner notices that a dwelling's panelboard schedule lists a
50-amp circuit for an electric vehicle supply equipment installation. The
3
, service calculation does not show the EV load. What should the
examiner request?
A. Deletion of the EV circuit
B. Inclusion of the EV load in the applicable load calculation
C. Replacement of the circuit with a 15-amp circuit
D. Calculation of only the receptacle load
Answer: B.
Rationale: Electric vehicle charging equipment can represent a
significant electrical load and must be appropriately accounted for in
the service or feeder calculation. Depending on the adopted code,
charging loads may also receive specific treatment as continuous or
managed loads.
6. A residential kitchen plan contains countertop receptacles spaced so
that a countertop area could require a cord-and-plug-connected
appliance to use an extension cord. Which plan-review principle
applies?
A. Countertop receptacle placement should satisfy the applicable
spacing and accessibility requirements
B. Extension cords are mandatory in all kitchens
C. One receptacle at the kitchen entrance is sufficient
D. Receptacle requirements apply only to floor outlets
Answer: A.
Rationale: Kitchen countertop receptacle layout is a major residential
electrical plan-review item. The examiner should review countertop
wall spaces, islands, peninsulas, appliance locations, and the required
receptacle spacing under the adopted electrical code.
