Part II of Article 368 governs the permitted installation of busways. Section 700.21 does not permit a manual control switch for emergency lighting to be placed in a motion picture projection booth or on a stage or platform; the switch shall be located in the lobby or at a convenient accessible location. a. Because of the presence of water and grounded surfaces that contributes to a potential shock hazard, Section 210.8(A)(7) confirms any 125-volt, 15- or 20-ampere receptacle installed within six (6) feet of a sink is required to be GFCI protected. Section 250.104(A)(1) requires metal water piping systems to be bonded to any of (1) the service entrance enclosure, (2) the grounded conductor at the service, (3) the grounding electrode conductor. A circuit breaker with an ampere rating of 75 amperes is not a standard ampere rating. A circuit breaker with an ampere rating of 75 amperes is not a standard ampere rating. The intent of Section 230.26 is to provide adequate vertical clearance of the conductors and prevent physical damage to the conductors and prevent persons from making accidental contact with the conductors which may create a shock hazard or electrocution. Also, receptacles located more than 20 inches above countertops or work surfaces may interfere with the cabinetry to be installed. The conductors and cables installed in underground installations must be of a type listed for use in wet locations. Section 210.8(A)(7) confirms that no matter what the location or room in a dwelling, where the 15- or 20-ampere, 125-volt eceptacles are installed within six (6) feet from the top inside edge of the bowl of the sink, GFCI protection must be provided to prevent a ground-fault shock hazard. Master Electrician License: A master electrician license is achieved after working for two years (about 4,000 hours) as a journeyman electrician and passing the Master Electrician Exam. Section 210.12(A) verifies AFCI protection is required for all 120-volt, 15- or 20-ampere branch-circuits that supply outlets in kitchens in dwellings.
The table is based on an ambient temperature of 86°C and not more than 3 current-carrying conductors in the raceway.
