San Francisco County Municipal Code Art. 215 Feeders

215.12(C)(1)(a) Revise this section as follows: (a) Means of Identification. The means of identification for conductor #8 AWG or larger shall be permitted to be by separate color coding, marking tape, tagging, or other approved means. Conductors of any size in cable assemblies may be suitably identified at all termination, connection and splice points. Phase Identification Colors for Feeders shall be as follows:

(1) 120/240 Volt 3-Wire Single Phase Systems – “A” Phase Black, “B” Phase Red. (2) 120/208 Volt 4-Wire 3-Phase Wye Systems – “A” Phase Black, “B” Phase Red, “C” Phase Blue. (3) 120/240 Volt 3-Phase Delta Systems – “A” Phase Black, “B” Phase (High Leg) Purple, “C” Phase Red. Information Note: New Construction or Complete Remodel of an Existing Building (4) 120/240 Volt 3-Phase Delta Systems – “A” Phase Black, “B” Phase Red, “C” Phase (High Leg) Purple. Information Note: Partial Remodel of an Existing Building – i.e. Replace Main Electrical Service where “C” Phase is Purple, & Re-Connect Existing Panels. (5) 277/480 Volt 4-Wire 3-Phase Wye Systems – “A” Phase Brown, “B” Phase Orange, “C” Phase Yellow. (6) Ungrounded conductors for other voltages shall be identified by different color coding, marking tape, tagging, or other approved means. (7) Branch Circuit Conductors for Switch Legs may be of a different color than the Ungrounded Feeder Circuit Conductor when suitably identified at pull boxes, junction boxes and outlet boxes with marking tape, tagging or other equally effective means. (8) In Multi-Family Dwelling Unit Buildings supplied by 120/208 Volt 4-Wire 3-Phase Systems, within Dwelling Units supplied by 120/208 Volt- 3-Wire Single Phase Systems, within Dwelling Units supplied by 120/208 Volt 3-Wire Single Phase Systems, Ungrounded Feeder Conductors shall be the following: a) 120/208 Volt 3 Wire Single Phase “A” Phase Black, “B” Phase Red b) 120/208 Volt 3 Wire Single Phase “B” Phase Red, “C” Phase Blue c) 120/208 Volt 3 Wire Single Phase “A” Phase Black, “C” Phase Blue d) Labeling Required at the Sub-Panel indicating which Phases Serve the Unit from the 120/208 Volt 4-Wire 3-Phase Multi / Meter Distribution System Informational Note: See Section 200.7 for limitations on identification of white or grey for Grounded Conductors, and 250.119 for prohibition on using Green for Ungrounded Conductors. Informational Note: See 210.5(C)(1) for additional information regarding Identification of Ungrounded Conductors.
