- Where must GFCI receptacles be installed in residential garages?arrow_forwardIs a GFCI receptacle permitted be installed as a replacement in an old installation where the 2-wire circuit has no equipment grounding conductor? _________________arrow_forwardA Type NM cable carries a branch circuit to the outside of a building, where it terminates in a metal weatherproof junction box. From this box, a short length of EMT is installed upward to another metal weatherproof junction box on which is attached a cluster of outdoor floodlights. The first box is located approximately 24 in. (600 mm) above the ground. To Meet Code, do the metal boxes and metal raceway have to be grounded? Yes _______________ No _______________ NEC _______________.arrow_forward
- a. The Code requires a minimum of two small-appliance circuits in a kitchen. Is it permitted to connect a receptacle in a dining room to one of the kitchen small-appliance circuits? _______________ What Code section applies to this situation? _______________ b. Are outdoor weatherproof receptacles permitted to be connected to a 20-ampere small-appliance circuit? _______________ c. Receptacles located above the countertops in the kitchen must be supplied by at least _______________ 20-ampere small-appliance circuits.arrow_forwardWhen installing GFCI and AFCI circuit breakers in a panelboard, it is permissible to connect them to a multiwire branch circuit. (True) (False).

- You are asked to replace an ungrounded receptacle (two wire) and there is not a source of ground available. 1. It is permissible to replace the receptacle with a GFCI receptacle? 2. If so, how must the receptacle plate be marked. Be sure and cite code references.arrow_forwardYou have determined that a 4700-ohm, 1⁄2-watt resistor on an electronic cir- cuit board is defective. Assuming room permits, can the resistor be replaced with a 4700-ohm, 1-watt resistor without damage to the rest of the board, or will the higher wattage resistor generate excessive heat that could damage other components?arrow_forwardPlans require the installation of surface-mounted fluorescent luminaires on the ceiling of a recreation room that is finished with low-density ceiling fiberboard. What sort of mark would you look for on the label of the luminaire? ________________________________________ ___________________________________________________________________________ ___________________________________________________________________________ ___________________________________________________________________________arrow_forward
