1.- The neutral wire is always white a) True b) False 2- Ground-fault Circuit-Interrupter Protection is necessary in a) bathrooms; b) garages; c) kitchens; d) all of them 3.- When a receptacle is installed in a metallic box it must always be connected to ground through the grounding hex screw a) True b) False mps. 4.. The allowable ampacity for a # 20 THIIN copper conductor is s- What size THHN conductor is req uired to supply a 250 amp feeder? a) No. 1/0 c) No. 3/0 b) No.2/0 d) No. 4/0 6.- What ground conductor is it necessary for two, No. 4/0 copper conductors per phase, installed in parallel (electrically connected at each end to form a single conductor)? 7.- Determine the ampacity of 4 No, 4 THHN conductors in a conduit at an ambient temperature of 100° F 8.- For a 3500 sq. ft. residential unit with the following loads: 1500 VA dishwasher 800 VA disposal 8000 VA range 5000 VA W.H. 5000 VA dryer 10000 VAA/C . Calculate: a) The feeder conductor size b) The grounding copper conductor sizeExplanation / Answer
1) the neutral wire is always green colour.. hence given statement is "false"
2) ground fault circuit- interrupt protection is necessary for all electrical circuits... Hence "all of the above" option is right.
