Extreme hazards can exist when energizing electrical distribution
equipment and switchboards . 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 switchboard
can cause catastrophic damage, injury, and death .
1. Prior to energizing the switchboard, turn OFF all overcurrent
devices and loads internal to the switchboard plus mains in
downstream equipment .
2. 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 .
3. If provided, use remote operators to close and energize switch-

Maintenance

It is essential to maintain the equipment in satisfactory condition .
To ensure continued quality service, a systematic maintenance
schedule is vital . Facility operation and local conditions vary to such
an extent that the schedule must be prepared to suit the conditions .
The maintenance schedule for individual devices, such as circuit
breakers, meters, fusible switches, and so on, should be based upon
recommendations contained in the individual instruction leaflet for
each device . Inspection and test operations should be coordinated
with an overall testing program to result in the least operating
inconvenience and system shutdowns .
