True False 2 Serves as a protective barrier to prevent contact with energized ('hot') parts within the unit. Front Cover Backpan Enclosure Dead Front 3 Feed-Through Lugs are a set of terminals in a service entrance panel where feeder cables to a distribution panel are connected. True False 4 A 240-volt circuit typically consists of four wires. They are: 2 hot, 1 neutral, 1 ground 1 hot, 1 neutral, 2 ground 1 hot, 2 neutral, 1 ground 2 hot, 2 neutral, 0 ground 5 On a Main Lug Only loadcenter, turning one of the branch circuit breakers to the OFF position, will stop power flow to the bus bars and other branch circuit breakers. True False 6 Regardless of ampere ratings, a "Lighting and Appliance" type of loadcenter is limited to 42 circuits in one enclosure. True False 7 Most homes have ______ amp service, and a 120/240V, single-phase, three-wire system. 50 120 200 500 None of the above 8 The power to a _________________ usually comes from a branch circuit breaker in the service entrance panel. Service entrance panel Distribution panel Termination panel Distribution transfomer 9 For safety reasons, the National Electrical Code (NEC) requires the service entrance panel's neutral to be grounded. Any downstream panels have their neutral _______ and _______. Insulated and Isolated Insulated and Terminated Isolated and Terminated Isolated and Bonded 10 Serves as an extension of the incoming power cables (main service conductors) and provides a means of affixing branch circuit breakers. Bonding Strap Twistouts Knockouts Bus Bars Stabs 11 One reason for the intentional grounding of electrical equipment is to lower the impedance of the ground path. In the event of a fault, this serves to ________ the current, allowing the overcurrent device to open ________. Decrease, faster Decrease, slower Increase, faster Increase, slower 12 A NEMA Type 1 enclosure: Is for indoor use Provides protection from accidental contact with enclosed equipment Is suitable for applications where unusual service conditions do not exist All of the above 13 Half size branch circuit breakers are designed to take up only half as much space in a loadcenter as a normal circuit breaker, but cannot just be installed 2 for 1 in any loadcenter. True False 14 The term used to describe a loadcenter used at the point where the power enters the building is a ____________. Service entrance panel Distribution panel Terminal panel Distribution transformer 15 The ____________ is where the main upstream circuit protection device has an interrupting rating equal to or greater than the available fault current of the system and downstream devices have lower ratings. Full rating method Equalizing method Series rated method Parallel rated method None of the above 16 Flush mounting is usually applied in industrial applications where the loadcenter is attached to and projects from the wall. True False 17 Main service conductors (Mains) bring electricity into a building from the power source. True False 18 A commercial/industrial service entrance panel is supplied with the same power system as a residential panel. True False 19 Double-pole circuit breakers plug-in to ______ stab(s) and feed ______ volts. One, 120 Two, 120 One, 240 Two, 240 20 A residential service entrance panel is typically used to supply lighting, receptacles and appliances in a home. True False
