insulation on the bond may overheat and smoke which should alert you to
descend the pole.
Using insulating gloves, attach the bond in the following manner:
Attach the small clip of the temporary bond to the cable suspension
1
strand in such a manner that it will not be in the way of work operations.
Attach the large clip of the bond wire to the fixture, conduit, or bare
2
vertical ground wire. Do not bond to a support bracket of multiple line
wire or the suspension strand of isolated cable. Never attach to street
light wires, terminals that wires are attached to, or a fixture that causes
the red LED to flash.
Insulating gloves may be removed only after the temporary bond is in place,
and then only if other protection requirements permit. Leave the temporary
bond in place until all work operations are complete at this pole for the day. If
the bond starts smoking, put on insulating gloves and descend the pole
immediately. In that case, avoid contact with the bond, the fixture, or its
wiring and refer to your company's safety procedures.
Upon completion of work operations on a pole, remove the temporary bond
by doing the following:
Put on insulating gloves.
1
Remove clip from the fixture, metallic conduit, or bare vertical ground
2
wire.
Remove the other clip, which was attached to the strand. If a spark is

detected when removing the bond, descend the pole immediately and
refer to your company's safety procedures.

Ungrounded Insulated Conductors

Insulated conductive objects in the presence of live AC current may tend to act
as antennae for AC potential. If these test as unsafe, they should be treated as
such and avoided.

Traffic Lights

Particular care must be taken when working near traffic light wiring or other
wiring which may become energized momentarily. Voltage tests made during
one part of a cycle may not be valid during another part.
