Section 8—Adverse Circumstances
This section includes, but is not limited to, all electrical components of
the switchboard.
NOTE:
Before attempting to re-energize the switchboard following adverse
circumstances, contact Schneider Electric Services at 1-888-778-2733 (US) or
1-800-565-6699 (Canada) for special instructions.
Inspection Following a Short Circuit
If a short circuit occurs, make a thorough inspection of the entire system, and verify
that no damage to conductors or insulation has occurred. High mechanical and
thermal stresses developed by short-circuit currents can damage conductors and
insulation. Check the overcurrent-protection device that interrupted the short-circuit
current for possible arcing damage.
Do not open sealed devices, such as molded case circuit breakers. Replace these
devices if they are damaged. Before energizing the switchboard, all unused circuit
breaker mounting spaces must be filled. For more information about these devices,
refer to the appropriate instruction manual listed in “Section 11—
Reference Publications” on page 54.
Clean-up Following a Short Circuit
The insulating properties of some organic insulating materials can deteriorate
during an electrical arc. If so:
1. Remove any soot or debris.
2. Replace carbon-tracked insulation.
Water-Soaked Switchboards
Do not clean or repair a switchboard that has been exposed to large volumes of
water or submerged at any time. Current-carrying parts, insulation systems, and
electrical components may be damaged beyond repair.
Do not energize the
switchboard.
Contact Schneider Electric Services at 1-888-778-2733 (US) or
1-800-565-6699 (Canada).
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Turn off all power supplying the switchboard before cleaning.
• Always use a properly rated voltage sensing device to confirm all power is off.
• Before energizing the switchboard, all unused circuit breaker mounting spaces
must be filled.
Failure to follow these instructions will result in death or serious injury.
