CAUTION
DO NOT TEST A CIRCUIT BREAKER WHILE IT’S IN SERVICE
AND ENERGIZED.
CAUTION
TESTING OF A CIRCUIT BREAKER THAT RESULTS IN THE
TRIPPING OF THE CIRCUIT BREAKER SHOULD BE DONE
ONLY WHEN THE PANELBOARD IS DE-ENERGIZED.
CAUTION
FAILURE TO SHORT OR DISCONNECT DURING
PANELBOARD TESTING WILL RESULT IN FAILURE OF
ELECTRONIC COMPONENTS.
WARNING
DISCONNECT POWER AT SOURCE BEFORE REMOVING OR
INSTALLING FUSES. HAZARDOUS VOLTAGE. WILL CAUSE
SEVERE INJURY OR DEATH.
Failure to disconnect control power during panelboard
testing will result in failure of electronic components and
void manufacturer’s warranty.
Pre-Energizing Panelboard Insulation Testing
Exercise extreme care to prevent the equipment from
being connected to the power source while tests are
being conducted.
Prior to energizing the panelboard, perform a Megger or DC
test of the panelboard’s insulation with the neutral isolated
from the ground and the switches and/or circuit breakers
open, conduct electrical insulation resistance tests from
phase to phase, phase to ground, phase to neutral, and
neutral to ground. Retain results for use to compare to
results produced in the future. Prior to testing, remove all
control power fusing and connections to products, which
will be damaged in this test. See above.
DO NOT USE AC Dielectric testing.
Test resulting in readings at or above 1 mega-ohm (MΩ) is
satisfactory.
Post-Testing
After testing, and with the panelboard de-energized,
reconnect all devices, control fusing and disconnects
removed prior to testing.
Securing the Panelboard
Install the dead front cover and trim parts on the panelboard
using hardware supplied by the manufacturer. Take caution
that conductors are not pinched between parts when
installing the dead-front cover and trim. All parts should be
aligned and secured when installed.
Do not leave holes or gaps in the dead-front construction.
Clean up any debris in and around the panelboard.
CAUTION
FAILURE TO DISCONNECT CONTROL POWER DURING
PANELBOARD TESTING WILL RESULT IN FAILURE OF
ELECTRONIC COMPONENTS.
CAUTION
TO PREVENT DAMAGE TO GROUND FAULT CONTROL
CIRCUITS, METERING CIRCUITS, OR OTHER CONTROL
CIRCUITS WHEN MEGGERING PANELBOARD, ISOLATE
CIRCUITS FROM
PANELBOARD SYSTEM BEFORE BEGINNING THE MEGGER
OPERATION. BE SURE TO RECONNECT THOSE CIRCUITS
AFTER MEGGER TESTS ARE COMPLETED. NOTEe:
SOME GROUND FAULT CIRCUITS MAY NOT BE FUSED,
THEREFORE ISOLATION OF THOSE CIRCUITS REQUIRES
DISCONNECTING WIRING FROM BUS BARS.
WARNING
DO NOT USE AC DIELECTRIC/MEGGER TESTING
Energizing Panelboard
Extreme hazards can exist when energizing electrical
distribution equipment and panelboards. Take all precautions
necessary to protect people and property when energizing
the equipment. Short circuits and ground faults may exist
as a result from inadequate installation. Short circuits and
ground faults within the panelboard can cause catastrophic
damage, injury and death.
1. Determine and always use proper Personnel
Protective Equipment (PPE) per NFPA 70E.
2. Prior to energizing the panelboard, turn OFF all
overcurrent devices and loads internal to the
panelboard plus mains in downstream equipment.
3. Verify and follow the sequence of energizing circuits
and loads. Verify phase sequencing on loads, such
as motors, which can be damaged or destroyed by
incorrect phase connections.
4. If provided, use remote operators to close and
energize panelboard, overcurrent devices and loads.
5. Beginning with the main(s), turn ON each overcurrent
device.
