When inspecting a service entrance, which condition would require the inspector to flag the installation as deficient?
Answer: Unprotected service entrance cable where it passes through the soffit
Service entrance cable must be protected where it passes through building structural components like soffits; unprotected cable is a NEC violation.
During a rough-in inspection of a residential bathroom, which finding is a code violation?
Answer: A receptacle outlet installed within 3 feet of the bathtub edge
NEC 406.9(B) prohibits receptacles within 3 feet of a bathtub or shower unless they are GFCI protected and installed on a wall surface not facing the tub.
An inspector observes that wire connectors (wire nuts) have been used to splice conductors inside a wall cavity with no junction box. The correct action is to:
Answer: Require a listed junction box with a cover plate to be installed
NEC 300.15 requires all splices to be made in listed boxes or conduit bodies; open-wall splices are prohibited regardless of insulation.
When conducting a final inspection on a commercial occupancy, what does the inspector verify regarding equipment grounding conductors in conduit systems?
Answer: That EGC size matches the circuit's overcurrent device per NEC Table 250.122
NEC Table 250.122 specifies minimum EGC sizes based on the rating of the circuit's overcurrent protective device.
Which inspection method is most appropriate for verifying conductor insulation integrity in an existing installation?
Answer: Megohmmeter (insulation resistance) testing
A megohmmeter measures insulation resistance in megohms and can detect degraded insulation that is not visible to the naked eye.
During an inspection, an inspector finds that a 240-volt, 2-pole breaker feeds a circuit with conductors that are both black. What is the correct assessment?
Answer: This is acceptable since both hots of a 240V circuit are ungrounded conductors
For a 240-volt 2-wire circuit with no neutral, both conductors are ungrounded (hot) conductors and may both be black per NEC 200.6.
What is the inspector's primary concern when checking a panelboard for 'double-tapping'?
Answer: That multiple conductors are connected to a single breaker terminal not rated for it
Double-tapping occurs when multiple conductors are landed on a single breaker terminal not listed for multiple conductors, creating loose connections and potential arcing.
