INSTALLATION

Essential Circuits

Consult with owner to clearly identify the circuits in building that are "essential".

It is important that you understand which circuits the owner wants to include as "Essential Circuits". Depending on the power consumed by these circuits, most or all of them can be switched to the Home Generator System for the duration of normal power interruption.

The wattage reference guide shown in Figure 2 will assist the owner with their decision-making process. It provides the wattage used by many ordinary household devices. Use it as a guide when selecting essential circuits. Review this information with the owner and convey any technical considerations that might affect the cost of installation.

Essential Circuit Selection

When selecting the essential circuits that will be switched to “Standby Power,” it is important that the sum of the combined circuit loads does not exceed the wattage/amperage capacity of the generator.To help you with your selection of essential circuits, please consider the following:

Add up the total wattage of all electrical devices to be connected at one time.This total should NOT be greater than the generator’s wattage capacity.

The rated wattage of lights can be taken from light bulbs. The rated wattage of tools, appliances and motors can usually be found on a data plate or decal affixed to the device.

If the appliance, tool or motor nameplate does not list wattage, multiply volts times the ampere rating to determine watts (Volts x Amps = Watts).

Some electric motors (induction types) require about three times more watts of power for starting than for running.This surge lasts for only a few seconds. Be sure you allow for this high starting wattage when selecting electrical devices that will be energized by the Home Generator System:

Figure the watts required to start the largest motor.

Add that to the total running watts of all other connected loads.

This Briggs & Stratton Home Generator System complies with the following “stationary standby power rating”:

The standby power rating is applicable for supplying power for the duration of normal power interruption. NO sustained overload capability is available for this rating.
