Wiring Tips
• Wire the switching panel similar
to wiring a lighting distribution
panel:
• Run feed and load wiring. No
other wiring or assembly
required.
The switching panel can provide
temporary lighting:
• Wire all loads.
• Leave the bypass jumpers in
place.
• Use branch circuit breakers at
the distribution panel to switch
lights on and off.
