Grounding The Generator - Porter Cable DTE325 Manual De Instrucciones

Read this manual. Do not attempt to operate
equipment until you have read this Manual for
Safety, Operation, and Maintenance Instruc-
tions.
NOTE: This manual is a general manual. Informa-
tion in this manual may or may not pertain to your
model. Please read carefully.
NOTE: Left and right describes the location of a
part with the operator facing the outlet panel.
REMOVE GENERATOR FROM CARTON
• Open carton from top.
• Cut carton along dotted lines.
• Remove all carton inserts.
• Remove generator through opening in carton.
• Fold handles up into operating position and tighten
knobs securely.
• Remove shipping block from
under the generator head by
unscrewing the bolt and
remove the wood block. It is
very important that this is
removed before starting your
generator. See Figure 1.
Never operate the unit with handles in the
folded position.
IMPORTANT: Before any attempt to start your genera-
tor be sure to check engine oil (See Engine Operator's
manual)

GROUNDING THE GENERATOR

A grounding lug is supplied with the generator for use
when required by local electrical ordinances. Refer to
article 250 of the National Electrical Code to clarify any
needed grounding information. Your local electric
company or a certified electrician should be able to
help you with this information.
NOTE: Your engine is already grounded to the frame by
a grounding strap.

OBTAINING ELECTRICITY FROM THE
GENERATOR
There are basically 2 ways to obtain electricity from a
generator:
1. Use of extension cords directly from the generator
to the appliance, lights, tools, etc.
2. Use of a double-throw transfer switch installed
directly to the main electrical supply outside of
house.
Extension Cords
When using an appliance or tool at a considerable
distance from the generator, a 3-wire extension cord
that has a 3-blade grounding plug and a 3-slot recep-
tacle that accepts the tool's plug MUST be used in
order to reduce the risk of electrical shock. A cord of
adequate size must be used. Using the following chart
to determine the minimum wire size required.

*NOTE: When amperage exceeds 20 amps; a 12 gauge
extension cord should not be used for long distances.
An extension cord that is hot to the touch is
overloaded. Repair or replace damaged exten-
sion cords immediately.
Double Throw Transfer Switch
Potential hazards exist when a portable electric genera-
tor is connected to the main electrical supply coming
into the house. It is at that point that the electrical
generator could feed back into the utility company's
system causing possible electrocution of workers who
are repairing the electrical lines.
To avoid back feeding of electricity into utility systems,
a double-throw transfer switch must be installed
between the generator and utility power. The Double-
Throw Transfer Switch should be installed by a li-
censed electrician and in compliance with all state and
local electrical codes. (When installing a Double-
Throw Transfer Switch, a minimum of 10 gauge
wiring must be used.)
The electrician should also install a sub-panel to isolate
the circuits you would want to use during an emer-
gency or electrical power outage. Your generator will
not be large enough to handle the load of all the lights,
appliances, TV, etc. at one time. To select which items
to run during the electrical power outage, see Wattage
Calculation section in this manual.
