Other requirements for rear-connected switchboards
On systems that require short circuit current ratings above 10,000
amperes rms, Cable Bracing may be required to restrict cable
movement . Lashing and lacing cables accomplish thi .
Pre-energizing procedures and inspection
Before energizing any switchboard, perform a comprehensive
inspection to make certain that the switchboard is ready to be
energized . This includes the following steps:
1.
Verify that the switchboard is not energized .
2.
Visually inspect the switchboard and remove all foreign
materials, such as, tools, scraps of wire and other debris from all
switchboard sections .
3.
Remove and discard all packing materials and temporary shipping
braces from the switchboard .
4.
Any accumulation of dust and dirt should be removed with a
vacuum cleaner . Use a lint-free cloth to remove dust and dirt
on other surfaces . Never use compressed air as this may blow
contaminants into electrical and/or electronic components .
Never use solvents or other chemicals to clean surfaces or
components .
5.
Visually inspect all ventilation points to ensure that there is no
blockage or debris . Remove all debris, if present .
6.
Verify all field bus and wire connections have the proper torque
per instructions on the switchboard and on components .
7.
All factory connections are made utilizing calibrated power
tools . However, vibrations do occur in transit and handling .
Verify factory connections by checking at least 10% of the total
factory connections for tightness . If this spot check reveals
loose connections, proceed to check all factory connections .
These connections include bus hardware connections, circuit
breaker and switch terminals, contactors, metering and other
connections, including the incoming terminals .
8.
Visually inspect switchboard insulators, bus bar and conductors
for damage . DO NOT ENERGIZE IF DAMAGE IS FOUND . Contact
Eaton .
9.
If fusible switch type overcurrent devices are used, verify proper
fusing has been selected and installed . Eaton does not typically
supply switchboards with these fuses .
Overcurrent devices
Overcurrent devices are typically shipped in either the open (OFF)
or “tripped” position . Manually close, and then open these devices
to ensure they are functioning properly . At the completion of this
process, be sure that the over-current device is in the “OFF” or
“tripped” position .
Inspect overcurrent devices for any visible damage . If damage is
found, DO NOT ENERGIZE the switchboard . Contact Eaton .
