PowlVac® Electrically Operated 15kV Ground and Test
per Long Island Railroad Specifications
8. Where the possibility of induced voltages
or stored electrical energy exists, ground
the phase conductors or circuit parts
before touching them. Where it could be
reasonably anticipated that the conductors
or circuit parts being de-energized
could contact other exposed energized
conductors or circuit parts, apply temporary
protective grounding equipment in
accordance with the following:
a..
Placement.
Temporary protective
grounding equipment shall be placed
at such locations and arranged in such
a manner as to prevent each employee
from being exposed to a shock hazard
(i.e., hazardous differences in electrical
potential). The location, sizing, and
application of temporary protective
grounding equipment shall be
identified as part of the employer’s job
planning.
b.
Capacity.
Temporary protective
grounding equipment shall be capable
of conducting the maximum fault
current that could flow at the point of
grounding for the time necessary to
clear the fault.

Informational Note: ATSM F855,
Standard
Specification for Temporary Protective
Grounds to be Used on De-energized Electric
Power Lines and Equipment,
is an example
of a standard that contains information on
capacity of temporary protective grounding
equipment.
c.
Impedance.
Temporary protective
grounding equipment and connections
shall have an impedance low enough
to cause immediate operation
of protective devices in case of
unintentional energizing of the electric
conductors or circuit parts.

Study this instruction bulletin and all other
associated documentation before uncrating
the circuit breakers.
Each user has the responsibility to instruct
and supervise all personnel associated with
usage, installation, operation, and maintenance
of this equipment on all safety procedures.
Furthermore, each user has the responsibility of
establishing a safety program for each type of
equipment encountered.
The ground and test devices described in this
instruction bulletin are operated by a
high-energy, high-speed mechanism that
is interlocked to provide specific operating
sequences. It is mandatory that the following
rules be observed to ensure the safety of
personnel associated with usage, installation,
operation, and maintenance of these ground
and test devices.
The safety rules in this instruction bulletin are
not intended to be a complete safety program.
The rules are intended to cover only some of the
important aspects of personnel safety related to
