In a branch circuit, the equipment grounding conductor is colored green. When several grounded conductors are in one feeder raceway, one of the grounded conductors should be colored white or gray. The other grounded conductors should have a colored stripe (but not green) over the white or gray, and a different color should be used for the stripe on each wire.

The most common raceway type used for branch-circuit installation is EMT, mainly because of its relatively easy bending and connection techniques. It is also much less expensive than other metal raceways.

Intermediate metal conduit (IMC) is a circular metal raceway with an outside diameter equal to that of rigid metal conduit (RMC). The wall thickness of IMC is less than that of RMC, so it has more interior room for conductors. IMC is lighter and less expensive than rigid metal conduit, but you can use it in all of the same locations as RMC.

230.7 Other Conductors in Raceway or Cable. Conductors other than service conductors shall not be installed in the same service raceway or service cable in which the service conductors are installed. Exception No. 1: Grounding electrode conductors or supply side bonding jumpers or conductors shall be permitted within service raceways.

Electrical nonmetallic tubing (ENT) is a pliable, corrugated, circular raceway made of PVC. It’s available in many colors, and sold in fixed lengths and on reels. EMT. You can use EMT exposed or concealed in [Sec. 358.10(A)]: (Fig. 2). • Concrete in direct contact with the earth per Sec. 358.10(B). • Dry, damp, or wet locations.

Color choice for the insulation of the conductors installed in a raceway depends on the type of circuit it serves. • For a 120-volt branch circuit, use a white insulated wire and a black insulated wire. • For a straight 240-volt circuit (like an electric water heater), use two black conductors or a black and a red conductor.

on the overcurrent protective device for the feeder or branch circuit. Metal raceways or auxiliary gutters in accordance with 250.118 or cable trays complying with 392.60(B) shall be permitted as the equipment grounding conductor. Requires a full-sized EGC in each raceway, and some discussion in the NEC handbook confirms this and explains why.
