trip setting, new device breaker‘s setting will be adjusted to well below the
settings of the supply breaker but adjusted properly to avoid nuisance tripping
of the new device.
If the new device breaker cannot be adjusted, then an adjustable type breaker
will be installed in lieu of non adjustable type.

“Hot Panel work (Electrical Live Service) may only be implemented on
panels and devices not exceeding 480 Volts and when the following
conditions exist: de-energizing the equipment will introduce additional or
increased hazards, where it is not feasible due to equipment design or
operational limitations and to avoid a significant business impact. It may
not be implemented for convenience or expedience. The criteria identified
in Fed/OSHA 1910.333(a)(1) and in this specification shall be followed. All
others will require a formal electrical shutdown. Removal and installation of
all bolt-on circuit breakers shall be done during a formal electrical
shutdown. The request for hot panel work may be originated by: (a) the
contractor through the assigned engineer responsible for the project which
requires the hot panel work, (b) the construction coordinator through the
engineer responsible for the project which requires the hot panel work, or
(c) the electrical engineer responsible for the building. All requests shall be
approved by the electrical engineer responsible for the building and then
forwarded to the Facilities Engineering Manager for approval. (The
Facilities Engineering Manager may delegate this approval authority to
qualified Facilities Engineers within the Facilities Engineering Department).
The request will include justification, panel number, panel schedule, area
affected, contractor P & C, T & M, or PO number and the scope of work to
be performed."
It will be mandatory that the requester of the work be present during the
performance of the hot panel work. Delegation of this responsibility must
receive additional approval.
a.
A panel is an electrical distribution panel which contains circuit
breakers/switches/fuses and does not include equipment control
panels, terminal panels, junction boxes, etc.
b.
All hot circuits in all types of panels shall be adequately protected with
temporary shields while work is occurring.
c.

location remote from the work area. Each step required to take highvoltage equipment out of service is to be listed and followed sequentially.
Switching orders must contain, as a minimum:
a. Employment of lockout/tagout for each disconnecting device
b. Testing of all exposed terminals, busways, and connections with a "glowtector" or "tic-tracer"
(or equivalent testing device) after the equipment has been de-energized, and before grounds
are applied
c. A list of all tools required for the job
d. Grounding of all exposed circuits with a ground set after the testing device indicates there is
no potential present
e. Isolation from backfeeds from alternate power sources, emergency power supplies, or
electronically coupled signals
f. Notification of personnel potentially affected by the work (but not involved) prior to power
shutdown, and again prior to power restoration
g. Compliance with the location's procedures for control of hazardous energy and electrical
safe work practices by any personnel not involved in the initial performance of the switching
orders

Such activities could include, for example, cleaning of high-voltage switchgear or evaluating
and adjusting terminations
2.
Switching orders signed by the originator, and reviewed by the supervising
individual and high-voltage technician.
3.
Restoration of power may be treated as a continuation of the original order, or
as a separate order. The restoration procedure is to list the step-by-step process
to:

area
b. Check for removal of all tools, tags, locks, grounds
c. Perform "high-pot" or phasing tests, where applicable
d. Secure panels and covers
e. Implement switching operations
4.
In emergency situations formal switching orders might not be appropriate. In
such situations, switching and repairs may be limited to the minimum necessary
to eliminate any hazard exposure to personnel or property. The high-voltage
technician and the individual supervising must agree on the appropriate actions
before each step is taken. The supervisor should have the authority to make
necessary emergency decisions. Written procedures are required to complete
work beyond the initial response to an emergency.

been isolated by opening breakers or disconnects between the equipment and all sources of
power
c. Test equipment approved for high voltage use only should be applied to all exposed
terminals and conductors in the equipment to verify de-energization
d. Using a "hot stick," the other end of the grounding set is touched to all exposed terminals
and conductors, after which the ground clamps are to be firmly attached to all phase terminals
or conductors
e. Use of protective grounding equipment capable of conducting the maximum fault current
available at the point of the system being grounded for the time necessary to clear the fault.
Determination of the required ground conductor size must be made by a competent individual.
In no case is the protective grounding equipment to have an amperage capacity less than that
provided by a No. 2 American Wire Gauge (AWG) copper conductor.
6.
Design, installation, modification, or extension of power distribution systems in
compliance with applicable regulatory or national consensus standards or
practices.
