10-8.8.2.2 Where it is not possible to install side guys, poles may need to be braced to
be self-supporting. Install pole bracing so that it does not interfere with climbing or with
street or highway traffic. Pole braced guys must not be used on poles which must be
climbed.

on the insulator petticoats. Do not screw down insulators too tightly because their tops
might break off, cutting gloves or hands.

ENERGIZED WORK. Energized work requirements are provided in
Chapter 8.

STREET LIGHTING.
10-10.1 Voltage Level. Street lighting circuits might be either low-voltage multiple
circuits or high-voltage series circuits. It is important that the type of circuit be identified
and deenergized before starting work because of the different voltage levels involved.
Workers must wear PPE in accordance with Chapter 4when working on street lighting
circuits.
10-10.2 Clearance Requirements. Street lighting lines, fixtures, and wires must be
considered energized, which requires wearing personnel protective equipment, unless a
Safe Clearance permit is obtained and the line grounded. The voltage of street lighting
circuit must be treated as that of the highest voltage occupying any of the poles on
which the street lighting circuit is run.
10-10.3 Multiple Street Lighting Circuits. Multiple street lighting circuits must be
treated with the same precautions as the circuits to which they are connected, unless
the circuit is located on a structure with a higher voltage wire, in which case it must be
considered to be at the higher voltage level.
10-10.4 Series Street Lighting Circuits. Before a series street lighting circuit is
opened and work is performed, the following procedures must be followed:
10-10.4.1 Disconnect the circuit from the source of supply by opening disconnecting
switches or other cutouts in accordance with a Safe Clearance permit and lockout-
tagout equipment. Do not depend on time switches or other automatic devices.
10-10.4.2 Jumper the circuit to avoid an open-circuit condition.
10-10.4.3 In replacing street light bulbs and lamp globes in street lighting brackets,
there is danger of an arc developing and causing serious damage and injury if the
spring clips in the receptacle do not make contact. These springs might have been
heated to the extent that they have lost their temper, or for some other reason, do not
close the circuit when the lamp socket is pulled out. Use approved changers with at
least 6 ft (1.8 m) handles for replacing lamps on series street lighting circuits. Workers
