A Wisconsin inspector is reviewing an installation under a provision that SPS 316 does not amend. The contractor cites a requirement first added to the 2023 NEC, and no local ordinance applies. The governing requirement is:
Correct answer: C - The 2017 NEC as incorporated and modified by Wisconsin SPS 316
A balanced three-phase motor load draws 100 kVA at 0.80 power factor. Capacitors raise the power factor to 0.95 while load demand and system voltage remain essentially unchanged. The expected supply-side effect is:
Correct answer: A - Lower line current and kVA, with essentially unchanged kW
A 2,000-square-foot dwelling has the required two small-appliance circuits and one laundry circuit. Before adding ranges, dryers, HVAC, or other loads, the standard-method demand assigned to general lighting, small-appliance, and laundry load is:
Correct answer: D - 5,625 VA
On a 120/240-volt multiwire branch circuit, removing one duplex receptacle opens the shared neutral to downstream loads. The two ungrounded conductors are on opposite legs but have independent breaker handles. Select the modification that corrects both conditions while retaining the existing conductors.
Correct answer: B - Pigtail the neutral and use a common disconnect for both ungrounded conductors
An uninterrupted dwelling kitchen countertop wall segment is 8 feet long. Two receptacles are 4 feet apart; the first is 30 inches from the left edge and the second is 18 inches from the right edge. How should the layout be evaluated?
Correct answer: B - Add a receptacle near the left end; 30 inches exceeds the 24-inch limit
A Wisconsin service designed under the 2017 NEC uses seven individually operable breakers, all grouped in one switchboard, to disconnect all ungrounded service conductors. No special arrangement or exception applies. The service must be revised by:
Correct answer: C - Reduce the grouped service disconnects to six or fewer
A load calculation for a new one-family dwelling is 86 amperes at 120/240 volts, single phase. Ignoring any larger utility minimum, determine the minimum service-disconnect rating.
Correct answer: A - 100 A, 3-wire
Before energization, a fault-current study shows 18 kA rms symmetrical available at an industrial control panel. Its feeder breaker is rated 22 kA interrupting, but the panel is marked 5 kA SCCR, and no listed series or current-limiting combination is documented. Identify the valid conclusion.
Correct answer: D - The panel SCCR is inadequate for the available fault current
A single 8-foot rod electrode tests at 34 ohms to earth. The building has no other qualifying grounding electrode, and the installer elects not to improve or retest the rod. Choose the next compliant action.
Correct answer: C - Install a supplemental electrode at least 6 feet from the first
A standby generator is connected through an existing transfer switch that switches only the ungrounded conductors; the neutral remains solidly connected to the service. The generator neutral bond is field-selectable, and the frame has an equipment grounding conductor back to the service. Without replacing the transfer switch, the arrangement that avoids parallel neutral current is:
Correct answer: C - Isolate the generator neutral and retain the frame equipment-grounding path
