210.12 Arc-Fault Circuit-Interrupter Protection Arc-fault circuit-interrupter protection shall be provided as required in 210.12(A) (B), and (C). The arc-fault circuit inter- rupter shall be installed in a readily accessible location. (A) Dwelling Units. All 120-volt, single-phase, 15- and 20-ampere branch circuits supplying outlets or devices installed in dwelling unit kitchens, family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways, laundry areas, or similar rooms or areas shall be protected by any of the means described in 210.12(A) (1) through (6): (1) A listed combination-type arc-fault circuit interrupter, installed to provide protection of the entire branch circuit (2) A listed branch/feeder-type AFCI installed at the origin of the branch-circuit in combination with a listed outlet branch-circuit type arc-fault circuit interrupter installed at the first outlet box on the branch circuit. The first outlet box in the branch circuit shall be marked to indicate that it is the first outlet of the circuit. (3) A listed supplemental arc protection circuit breaker installed at the origin of the branch circuit in combination with a listed outlet branch-circuit type arc-fault circuit interrupter installed at the first outlet box on the branch circuit where all of the following conditions are met: a. The branch-circuit wiring shall be continuous from the branch-circuit overcurrent device to the outlet branch- circuit arc-fault circuit interrupter. b. The maximum length of the branch-circuit wiring from the branch-circuit overcurrent device to the first outlet shall not exceed 15.2 m (50 ft) for a 14 AWG conductor or 21.3 m (70 ft) for a 12 AWG conductor. c. The first outlet box in the branch circuit shall be marked to indicate that it is the first outlet of the circuit.
A tag line from bobselectricco.com link above, seems like another 'new' item is mandatory with the '14 changes.
"AFCI receptacles must be UL listed for compatibility with specific magnetic circuit breakers that are commonly found on the market today or used downstream from a new type of breaker called an SAP (Supplemental Arc Protection) breaker."
Reading thru the entire text, some text alludes that the AF device works with 'standard mainstream breakers'; yet the above quote is deeper within the text??
Greg: Existing old "FPE" 150 amp panel. EC adding three (3) new 2 wire circuits. He installs a 60 amp, 2 pole FPE CB, 1" EMT raceway (3'6"), 5' +/- conductor length. into a 100 amp MLO new sub panel. Three compliant AFCI CBs in new sub panel. Normal TR devices.
IMHO, that is compliant, and the AFCI receptacles are not required. Agree??
