Don't Overloadthe Generator - Generac Power Systems 005778-0 Owner's Manual

+ 2.4.1.1 Special R equirements
There may be Federalor State Occupational Safety and Health
Administration (OSHA)regulations,local codes, or ordinancesthat
apply to the intendeduse of the generator.
Please consult a qualified electrician, electrical inspector, or the
local agency havingjurisdiction:
* In some areas, generators are required to be registered with
local utility companies.
* If the generator is used at a construction site, there may be
additionalregulationswhich must be observed.
+ 2.4.1.2 Connecting t o a Building's Electrical System
Connections for standby power to a building's electrical system
must be made by a qualified electrician. The connection must
isolate the generatorpower from utility power or other alternative
power sources and must comply with all relatedlaws and codes.
2.4.2 GROUND/NG THEGENERATOR
The National Electrical Code requires that the frame and
external electrically conductive parts of this generator be
properlyconnected to an approvedearth ground(Figure 6).
Local electrical codes may also require proper grounding of the
unit. Forthat purpose, connecting a No. 10 AWG (AmericanWire
Gauge) stranded copper wire to the grounding lug and to an
earth-driven copper or brass grounding rod (electrode) provides
adequateprotectionagainst electricalshock. However,local codes
may vary widely. Consultwith a local electricianfor grounding
requirements in the area.
Proper groundingof the generatorwill help preventelectrical
shock in the event of a ground fault condition in the generator
or in connected electrical devices. Proper grounding also helps
dissipate static electricity, which often builds up in ungrounded
devices.

2.4.3 NEUTRAL TOFRAMEGROUNDING
If service work is performed on the alternator, DO NOT discard
the white jumper wires from the terminal block to the alternator
ground, located on the rear bearing carrier. Alway make sure the
wires are properly connected before using the generator after
alternatorservice work is done (Figure7).

DONOT DISCARD
Failure to reconnect these wires may create a
potential shock hazard when the generator is
running!
2.4.4 CONNECT/NG ELECTR/CAL LOADS
DO NOTconnect 240 Volt loadsto 120 Volt receptacles.DONOT
connect 3-phase loads to the generator.DO NOT connect 50 Hz
loads to the generator.
* Let engine stabilize and warm up for a few minutes after
starting.
* Plug in and turn on the desired 120 or 240 Volt AC, single
phase, 60 Hz electrical loads.
* Add up the ratedwatts (or amps) of all loadsto be connected
at one time. This total should not be greaterthan (a) the rated
wattage/amperage capacity of the generator or (b) circuit
breakerratingof the receptaclesupplyingthe power.See "Don't
Overloadthe Generator".
2.5 DON'T OVERLOAD THEGENERATOR
Overloadinga generator in excess of its rated wattage capacity
can result in damageto the generatorand to connectedelectrical
devices. Observethe following to preventoverloadingthe unit:
* Add up the total wattageof all electricaldevicesto be connected
at one time. This total should NOT be greater than the
generator'swattage capacity.
* The ratedwattage of lights can be taken from light bulbs. The
rated wattage of tools, appliances and motors can usually be
found on a data label or decal affixedto the device.
