PB 1.1-2007

Section 9
ENERGIZING EQUIPMENT
WARNING—HAZARDOUS VOLTAGES IN ELECTRICAL EQUIPMENT CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH. ENERGIZING A PANELBOARD FOR THE FIRST TIME AFTER
INITIAL INSTALLATION OR MAINTENANCE IS POTENTIALLY DANGEROUS.
9.1 QUALIFIED
PERSONNEL
Only qualified personnel should energize equipment for the first time. If short circuit conditions caused by
damage or poor installation practices have not been detected in the procedures specified in Section 7,
serious personal injury and damage can occur when the power is turned on.
9.2
LOAD ON THE PANELBOARD
There should be no load on the panelboard when it is energized. Turn off all of the downstream loads.
9.3
ENERGIZED IN SEQUENCE
The equipment should be energized in sequence by starting at the source end of the system and working
towards the load end. In other words, energize the main devices, then the feeder devices, and then the
branch-circuit devices. Turn the devices on with a firm positive motion.
9.4
LOADS SUCH AS LIGHTING CIRCUITS, CONTACTORS, HEATERS, AND MOTORS
After all main, feeder, and branch circuit devices have been closed, loads such as lighting circuits,
contactors, heaters, and motors may be turned on.
