1What work does NAC 624.240 authorize under Nevada subclassification C-6B Electrical Signs?
A.Fabrication, installation and erection of electrical signs and the installation of any related wiring
B.Billboard erection only, with no electrical lighting permitted
C.Painting of art and advertising messages on signs, with no erection work
D.Sheet-metal work only, with electrical connections left to a C-2 contractor
Explanation: NAC 624.240(2)(b) defines C-6B as the fabrication, installation and erection of electrical signs and the installation of any related wiring. That is the official Nevada State Contractors Board scope PSI tests. C-6A outdoor advertising expressly excludes electrical lighting, and C-6D is painted signs only.
2NEC 2017 Article 600 covers the installation of conductors, equipment, and field wiring for which systems?
A.Electric signs and outline lighting, including retrofit kits
B.Only factory-wired portable lamps under Article 410
C.Only service-entrance conductors under Article 230
D.Only swimming-pool underwater luminaires under Article 680
Explanation: NEC 2017 600.1 covers conductors, equipment, and field wiring for electric signs and outline lighting, and it also covers retrofit kits. Outline lighting is an arrangement of lamps or electric-discharge lighting that outlines or calls attention to a building feature or window. Neon art forms not attached to a sign body are treated as skeleton tubing.
3Per NEC 2017 600.5(A), each commercial occupancy accessible to pedestrians must have at least one sign or outline-lighting outlet at each entrance to each tenant space. What is the minimum rating of the branch circuit that supplies that outlet?
A.20 amperes, and the circuit shall supply no other load
B.15 amperes, shared with the storefront receptacles
C.30 amperes, shared with the HVAC rooftop unit
D.40 amperes, reserved for a future pylon sign
Explanation: NEC 2017 600.5(A) requires an accessible outlet at each pedestrian tenant entrance, supplied by a branch circuit rated at least 20 amperes that supplies no other load. Service hallways and delivery-only entrances do not trigger the outlet. The dedicated 20-ampere circuit is the code minimum, not a suggestion.
4How does NEC 2017 600.5 treat branch circuits that supply electric signs for load calculations?
A.They are considered continuous loads
B.They are considered noncontinuous loads
C.They are calculated at 80 percent of nameplate without the 125 percent factor
D.They are exempt from Article 220 load calculations
Explanation: NEC 2017 600.5(B) treats branch circuits that supply signs as continuous loads. Continuous-load conductor and overcurrent-device sizing in 210.19(A)(1) and 210.20(A) therefore uses 125 percent of the sign load. That is why a 16-ampere sign load requires a 20-ampere circuit.
5Under NEC 2017 600.5(B), what are the maximum branch-circuit ratings for neon-tubing installations versus other signs and outline lighting?
A.Neon tubing 30 amperes or less; other signs and outline lighting 20 amperes or less
B.Neon tubing 20 amperes or less; other signs 30 amperes or less
C.Both types 40 amperes or less
D.Both types 15 amperes or less
Explanation: NEC 2017 600.5(B) limits neon-tubing branch circuits to 30 amperes or less and limits other signs and outline lighting systems to 20 amperes or less. The higher neon ceiling exists because neon transformer primary currents can be larger, but ordinary LED or fluorescent sign circuits stay on 20-ampere circuits.
6NEC 2017 600.6 requires each circuit for a sign, outline lighting system, or skeleton tubing to be controlled by an externally operable switch or circuit breaker that does which of the following?
A.Opens all ungrounded conductors, and opens them simultaneously on a multiwire branch circuit
B.Opens only the grounded conductor so the sign stays referenced to earth
C.Opens one ungrounded conductor and leaves the other hot for night lighting
D.Opens the equipment grounding conductor to isolate the cabinet
Explanation: NEC 2017 600.6 requires an externally operable switch or circuit breaker that opens all ungrounded conductors. On a multiwire branch circuit the device must open all ungrounded conductors simultaneously, consistent with 210.4(B). The grounded conductor and the equipment grounding conductor stay connected so the sign remains referenced and bonded.
7When NEC 2017 600.6 locates a sign disconnect “within sight” of the sign, what does Article 100 require for that phrase?
A.The disconnect must be visible and not more than 50 feet from the sign
B.The disconnect may be in any locked electrical room in the same building
C.The disconnect may be any distance away if it is labeled
D.The disconnect must be mounted on the transformer secondary bushing
Explanation: Article 100 defines “within sight from” as visible and not more than 50 feet distant. NEC 2017 600.6 uses that definition when the disconnect is placed within sight of the sign or controller. A remote locked room that is more than 50 feet away, or not visible, is not “within sight.”
8Unless mechanically protected from physical damage, NEC 2017 600.9(A) requires a sign or outline lighting system to be at least how far above areas accessible to vehicles?
A.14 feet
B.8 feet
C.10 feet
D.18 feet
Explanation: NEC 2017 600.9(A) requires 14 feet of clearance above areas accessible to vehicles unless the sign is mechanically protected from physical damage. That is a sign-body clearance, not the 225.18 overhead-conductor clearance. Public streets and truck-traffic parking still need 18 feet for overhead conductors under 225.18.
9NEC 2017 600.3 requires electric signs, section signs, and outline lighting to be listed. Which field-installed work is exempt from that listing requirement if it is wired to Chapter 3 methods?
A.Field-installed skeleton tubing, and field-installed outline lighting wired to Chapter 3
B.Every factory section sign shipped in more than one crate
C.Every LED retrofit kit installed in a listed host sign
D.Every portable indoor banner with a 120-volt attachment plug
Explanation: NEC 2017 600.3 requires listing of electric signs, section signs, and outline lighting. Two field-installed exceptions exist: skeleton tubing, and outline lighting that is wired in accordance with Chapter 3. Section signs and retrofit kits still have to be listed products installed to their instructions.
10NEC 2017 600.4 requires signs and outline lighting systems to be permanently and durably marked with the manufacturer’s identification. Where must that marking remain visible?
A.It need not be visible after installation, but it must be visible during servicing; wet-location markings must be weatherproof
B.It must remain readable from the public sidewalk after installation
C.It may be painted over if the permit number is on the disconnect
D.It is required only on portable signs
Explanation: NEC 2017 600.4(A) requires a permanent manufacturer identification. 600.4(C) says the marking need not be visible after installation but must be visible during servicing. 600.4(D) requires weatherproof markings in wet locations. Missing or counterfeit markings are a reason not to energize the sign.
