Grounding electrical equipment.
Hazardous voltage can
severe injury or death. Electrocution
is possible whenever electricity is
present. Ensure you comply with all
applicable codes and
Electrically ground the generator set,
transfer switch, and related equipment
and electrical circuits. Turn off the main
circuit breakers of all power sources
before servicing the equipment. Never
contact electrical leads or appliances
when standing in water or on wet
ground because these conditions
increase the risk of electrocution.
Disconnecting the electrical load.
Hazardous voltage can
severe injury or death. Disconnect
the generator set from the load by
turning off 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.
Short circuits.

injury or death. Short circuits can
cause bodily injury and/or equipment
damage. Do not contact electrical

Remove all jewelry before servicing the
equipment.
Electrical backfeed to the utility.
Hazardous backfeed voltage can
cause severe injury or death.
Connect the generator set to the
building/marina electrical system only
through an approved device and after
the building/marina main switch is
turned off. Backfeed connections can
cause severe injury or death to utility
personnel working on power lines
and/or personnel near the work area.
Some states and localities prohibit
unauthorized connection to the utility
