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 installing the
EcoVisor
™
environmental monitoring system.
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 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
the EcoVisor.

1. Only supervised and qualified personnel
trained in the usage, installation, operation,
and maintenance of a circuit breaker shall
be allowed to work on this equipment. It is
mandatory that the appropriate instruction
bulletins, supplements, and service
advisories be studied, understood, and
followed.
2. Maintenance programs must be consistent
with both customer experience and
manufacturer’s recommendations,
including service advisories and instruction
bulletin(s). A well planned and executed
routine maintenance program is essential
for circuit breaker’s reliability and safety.
3. Service conditions and circuit breaker
applications shall also be considered in the
development of safety programs. Variables
include ambient temperature; humidity;
actual continuous current; thermal cycling;
number of operations; interrupting duty;
and any adverse local conditions including
excessive dust, ash, corrosive atmosphere,
vermin and insect infestations.
