The NEC does permit spare raceways. The NEC does not require termination fitting for the grounding electrode conductor. Splices are permitted in a cabinet, see 312.8(A)(4). Bundel of conductors are okay, see 310.15(C). Phase conductors in this panel are not required to be identified. VIOLATION: The neutral conductor identification required by 200.6(B) is not at its terminations. #electrican #electricalcontractor #mikeholt #sparkylife #electricalapprentice | Mike Holt Enterprises

Insulated neutral conductors 6 AWG and smaller must be identified [200.6(A)]: (1) A continuous white outer finish. (2) A continuous gray outer finish. Insulated neutral conductors 4 AWG or larger must be identified [200.6(B)]: (1) A continuous white outer finish along the conductor’s length. (2) A continuous gray outer finish along the conductor’s length. (4) White or gray at its terminals at the time of installation that encircle the conductor insulation. #electrican #electricalcontractor #mike
