B. Internal fixture wiring shall be minimum No. 14 AWG, type AF or TF (150 deg. C) with minimum
300-volt insulation. This means 90 deg C cannot enter the fixture.
C. Branch circuit wiring shall be done with color coded conductors, using the same code throughout.
1.
Mechanical Ground-Green; Single & 3Way Return, Orange Tracer.
2.
Neutral 208/120White; 3Way Traveler, Yellow Tracer.
3.
Phase A 208/120Black; Start Control, Black Tracer.
4.

7.
Phase B 480/277Orange.
8.
Phase C 480/277Yellow.
9.
Neutral 480/277Natural Gray.
D. Colors as selected for the purpose of identifying circuits shall be applied to the wire. The color
shall be color fast, and capable of withstanding cleaning in the event wire becomes soiled.
E. Tag circuit wires in cabinets with 1/2 inch diameter l/16 inch thick tags securely fastened to
conductors or with approved tape numbering at time wires are pulled in and tested. Circuit
numbers shall be stamped into the tags or permanent tape numbers. Tags or tape shall not be
removed.
F. A minimum of 6 inch loops or ends shall be left at each outlet for installation of future devices or
fixtures. Wires in outlet boxes not for the connection to fixtures at that outlet, shall be rolled up,
connected together and taped or capped with wire nuts.
G. Branch circuit sizing:
1.
Branch circuit wiring from panels to an outlet on the circuit shall be minimum No. 12
AWG. Exit light or emergency wiring shall be minimum No. 10 AWG.

cable outside diameter (in.). Maximum strain should not exceed 1,000 lbs./sq. in.
