Porter-Cable H451CS Assembly, Remove Generator from Carton, Grounding the Generator

ASSEMBLY

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.

•(If equipped) See portability Kit instructions to assemble the portability kit.

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 com- pany 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 dis- tance from the generator, a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot receptacle 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 deter- mine the minimum wire size required.

Extension Cord Wire Gauge Chart

Cord	Wire Gauge
Length	Size	Amperage
0 to 100 ft.	12 ga.	*Up to 20 amp draw
0 to 100 ft.	10 ga.	Up to 30 amp draw

*NOTE: When amperage exceeds 20 amps; a 12 gauge extension cord should not be used for long dis- tances.

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 gen- erator could feed back into the utility company's sys- tem 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 licensed 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 emergen- cy or electrical power outage. Your generator will not be large enough to handle the load of all the lights, ap- pliances, TV, etc. at one time. To select which items to run during the electrical power outage, see Wattage Calculation section in this manual.
