Disconnecting the electrical load.
Hazardous voltage can
severe injury or death. Disconnect
the generator set from the load by
opening the line circuit breaker or by
disconnecting the generator set output
leads from the transfer switch and
heavily taping the ends of the leads.
High voltage transferred to the load
during testing may cause personal
injury and equipment damage. Do not
use the safeguard circuit breaker in
place of the line circuit breaker. The
safeguard circuit breaker does not
disconnect the generator set from the
load.

Electrical backfeed to the utility.
Hazardous backfeed voltage can
cause severe injury or death.
Connect the generator set to the

through an approved device and after
the building/marina main switch is
opened. Backfeed connections can
cause severe injury or death to utility
