Generac Portable Products Power Transfer System

3

1. A licensed electrician or qualified professional

2. During installation, the installer is required to

remove the cover from the building power

distribution panel (referred to herein as a ‘load

center’.) To reduce the risk of electrical shock, the

Main circuit breaker must be turned OFF while the

load center cover is removed.

3. DO NOT OVERLOAD THE GENERATOR.

Overloading a generator in excess of its rated

wattage capacity will trip generator circuit

breakers.

4. Always plug the connecting cord set into the

connection box and generator BEFORE starting

the generator. Always shut the generator down

before detaching the cord set.

5. Portable generators attached to this Power

Transfer System must be operated outside, in

accordance with warnings and instructions found in

the generator’s Owner’s Manual.

The installer and the homeowner decide which circuits

are to be powered by the generator during a utility

power outage:
• The plan should ensure that no single circuit load

exceeds 15 Amps.

• The plan should also identify circuits that exceed the

15 Amp maximum.

• During generator operation, the homeowner should

use only necessary household items and to alternate

use of larger loads, such as water pump or electric

skillet. The installer will instruct the homeowner in

appropriate load management techniques.

Three methods of determining loads are given here:
Measure Actual Loads
The installer uses a clamp-on ammeter to measure

each of the actual desired loads to ensure each total

circuit draws less than 15 Amps.

Sum Loads from Data Plates
The installer inspects each desired device, notes

current consumption found on labels on each

appliance, then adds all loads on each circuit:
• The rated current of appliances and motors can

usually be found on a data plate or decal affixed to

the device.

• The rated wattage of lights can be taken from light

bulbs.

• Some electric motors, such as induction types,

require about three times more power for starting

than for running. This surge of power lasts for only a

few seconds when starting such motors. Be sure to

allow for this high starting load.

Estimate Loads
The third method estimates total circuit loads based on

information given in Figure 1.
