1926.404(c) Outside Conductors and Lamps

OSHA 1926 Construction > K Electrical > 1926.404 Wiring Design and Protection > 1926.404(c) Outside Conductors and Lamps
JUMP TO FULL CODE CHAPTER

1926.404(c)(1) 600 Volts, Nominal, or Less

Paragraphs (c)(1)(i) through (c)(1)(iv) of this section apply to branch circuit, feeder, and service conductors rated 600 volts, nominal, or less and run outdoors as open conductors.

1926.404(c)(1)(i) Conductors on Poles

Conductors supported on poles shall provide a horizontal climbing space not less than the following:

1926.404(c)(1)(i)(A)

Power conductors below communication conductors-30 inches (762 mm).

1926.404(c)(1)(i)(B)

Power conductors alone or above communication conductors: 300 volts or less-24 inches (610 mm); more than 300 volts-30 inches (762 mm).

1926.404(c)(1)(i)(C)

Communication conductors below power conductors: with power conductors 300 volts or less-24 inches (610 mm); more than 300 volts-30 inches (762 mm).

1926.404(c)(1)(iii) Clearance From Building Openings

Conductors shall have a clearance of at least 3 feet (914 mm) from windows, doors, fire escapes, or similar locations. Conductors run above the top level of a window are considered to be out of reach from that window and, therefore, do not have to be 3 feet (914 mm) away.

1926.404(c)(1)(iv) Clearance Over Roofs

Conductors above roof space accessible to employees on foot shall have a clearance from the highest point of the roof surface of not less than 8 feet (2.44 m) vertical clearance for insulated conductors, not less than 10 feet (3.05 m) vertical or diagonal clearance for covered conductors, and not less than 15 feet (4.57 m) for bare conductors, except that:

1926.404(c)(1)(iv)(A)

Where the roof space is also accessible to vehicular traffic, the vertical clearance shall not be less than 18 feet (5.49 m), or

1926.404(c)(1)(iv)(B)

Where the roof space is not normally accessible to employees on foot, fully insulated conductors shall have a vertical or diagonal clearance of not less than 3 feet (914 mm), or

1926.404(c)(1)(iv)(C)

Where the voltage between conductors is 300 volts or less and the roof has a slope of not less than 4 inches (102 mm) in 12 inches (305 mm), the clearance from roofs shall be at least 3 feet (914 mm), or

1926.404(c)(1)(iv)(D)

Where the voltage between conductors is 300 volts or less and the conductors do not pass over more than 4 feet (1.22 m) of the overhang portion of the roof and they are terminated at a through-the-roof raceway or support, the clearance from roofs shall be at least 18 inches (457 mm).

1926.404(c)(1)(ii) Clearance From Ground

Open conductors shall conform to the following minimum clearances:

1926.404(c)(1)(ii)(A)

10 feet (3.05 m)-above finished grade, sidewalks, or from any platform or projection from which they might be reached.

1926.404(c)(1)(ii)(B)

12 feet (3.66 m)-over areas subject to vehicular traffic other than truck traffic.

1926.404(c)(1)(ii)(C)

15 feet (4.57 m)-over areas other than those specified in paragraph (c)(1)(ii)(D) of this section that are subject to truck traffic.

1926.404(c)(1)(ii)(D)

18 feet (5.49 m)-over public streets, alleys, roads, and driveways.

1926.404(c)(2) Location of Outdoor Lamps

Lamps for outdoor lighting shall be located below all live conductors, transformers, or other electric equipment, unless such equipment is controlled by a disconnecting means that can be locked in the open position or unless adequate clearances or other safeguards are provided for relamping operations.
