Step 3: Wiring the Bus Bars
Ensure circuit breakers are OFF and the transfer switch is
locked out from Source power prior to connection.
Failure to install transfer switch will create the potential for
the source to energize the ASCO SERIES 300 Quick

4. If metallic conduit is used, connect ground wire from
ground bushing on conduit to the ground connection point
in the upper right quadrant of the panel
5. Ground conductor must be a minimum of #2 AWG
6. Conduit shall NOT be relied upon to provide grounding
protection to tap box
7. Vacuum entire upper chamber to ensure no metal shavings
