2.4.2 CONNECT/NGTHEGENERATORTOA BU/LD/NG'$
ELECTR/CALSYSTEM
Connectionsfor standby power to a building's electrical system
must be made by a qualified electrician and in strict compliance
with all national and local electrical codes and laws. The
connection must isolatethe generatorpower from utility power or
other alternativepowersources.
NOTE:
Because the generatorequipment ground is bonded to the AC
neutral wires in the generator(see Figure 8), either a 3-pole
transferswitch or a 2 pole transferswitch with a switching
neutral kit is requiredto connectthis generatorto a building
load. in this application the generator becomes a separately
derived system(see NEC250.20 (D)), and must be grounded
in accordance with the national or local electrical code
requirements.
GroundingtheGeneratorina BuildingStandbyApplication
_ he National Electrical Code requires that the
frame and external electrically conductive parts
of this generator be properly connected to an
approved earth ground.
Local electrical codes may also require proper grounding of the
unit (Figure 10). For that purpose, connecting a No. 10 AWG
(AmericanWire Gauge)strandedcopper wire to the groundinglug
and to an earth=drivencopper or brass groundingrod (electrode)
provides adequate protection against electrical shock. However,
local codes mayvary widely. Consultwith a localelectrician for
grounding requirementsinthe area.
Proper groundingof the generator will help preventelectrical
shockin the eventof a groundfault condition inthe generatoror in
connectedelectricaldevices.Propergroundingalso helps dissipate
static electricity,which often builds up in ungroundeddevices.

2.5 DON'TOVEBLOADTHEGENEBATOB
Overloadinga generator in excess of its rated wattage capacity
can result in damageto the generatorand to connectedelectrical
devices.Observethe following to preventoverloadingthe unit:
* Addupthe total wattageof all electricaldevicesto beconnected
at one time. This total should NOT be greater than the
generator'swattage capacity.
* The rated wattage of lights can betaken from light bulbs. The
rated wattage of tools, appliancesand motors can usually be
found on a data labelor decal affixedto the device.
* If the appliance,toot or motor does not give wattage,multiply
volts times ampererating to determinewatts (volts x amps =
watts).
* Some electric motors, such as induction types, require about
three times more watts of power for starting than for running.
This surge of power lasts only a few seconds when starting
suchmotors. Makesureto allowfor high startingwattagewhen
selectingelectrical devicesto connect to the generator:
1. Figurethe watts neededto start the largestmotor.
2. Add to that figure the running watts of all other connected
loads.
The WattageReferenceGuideis providedto assist in determining
how many items the generatorcan operateat onetime.
NOTE:
All figures are approximate.See data label on appliance for
wattage requirements.
