POWER ARC 5000
A-8
POWER CORD CONNECTIONS TO TWIST-
LOCK PLUGS
Refer to the appropriate diagram above for proper
connection of power cord wires to the Twist-Lock plug
terminals. Also, read the instruction sheet supplied
with the Twist-lock plug.
PLUGS AND HAND-HELD EQUIPMENT
For further protection against electric shock, any 120
volt hand-held equipment connected to the generator
receptacles must use a three-blade, grounded type
plug or an Underwriter’s Laboratories (UL) approved
double insulation system with a two-blade plug.
CIRCUIT BREAKERS
The POWER ARC 5000 has circuit
breakers for overload protection.
When the machine is operated in high
temperature environments, the
breakers may tend to trip at lower loads than normal-
ly.
Never bypass the circuit breakers. Without overload
protection, the POWER ARC 5000 could overheat
and/or cause damage to the equipment being used.
PREMISES WIRING
The POWER ARC 5000 three-wire, grounded neutral
generator allows it to be connected to premises
wiring. However, the wiring procedure needed to
meet the National Electric Code (NEC) regulations as
well as city ordinances can be confusing. Matters get
worse depending on whether you want the machine
to be “hardwired” to the premises or only connected
temporarily.
Only a licensed, certified, trained electrician should
install the machine to a premises or residential electri-
cal system. Be certain that:
• The premises is isolated and no feedbacking into
the utility system can occur. Certain state and
local laws require the premises to be isolated
before the generator is linked to the premises.
Check your state and local requirements.
• A double pole, double throw transfer switch in con-
junction with the properly rated double throw cir-
cuit breaker is connected between the generator
power and the utility meter.
Remember that the POWER ARC 5000 is intended
only for backup, intermittent use. It cannot withstand
long-term use without proper maintenance. See the
MAINTENANCE section of this manual for more
information.
Certain electrical devices cannot be powered by the
POWER ARC 5000. Refer to Table A.2 for these
devices.
