Briggs & Stratton Power Products Automatic Transfer Switch

Installation and Owner’s Manual

Equipment Description

Mounting Dimensions

These switches are a new generation of transfer switches that are intended to transfer the entire load of normal residential installations.The load is connected either to utility power (normal) or home standby power (emergency).The transfer switch monitors utility and generator voltages and will automatically connect to the appropriate source of power.

Major components of the transfer switch are a 2 pole double throw transfer switch, control circuit board, fused utility terminals and interconnecting wiring.

The transfer switch is solenoid-operatedfrom utility or generator inputs and contain suitable mechanical and electrical interlock switches to eliminate the possibility of connecting the utility service to the generator output. It has ratings capable of switching full utility power into the residence. In addition, a manual override lever is provided for the transfer function.

The control circuit board has active circuits sensing utility and generator voltages. It creates a signal for the generator start-up,switch transfer, retransfer when utility is restored and generator cool down periods.The control board also contains red and green LED’s indicating the power sources available and two relay operated contacts that provide supervisory control of external loads.

INSTALLATION

Mounting Guidelines

The Automatic Transfer Switch is enclosed in a NEMA Type 3R enclosure suitable for indoor/outdoor use. Guidelines for mounting the Automatic Transfer Switch include:

Install the switch on a firm, sturdy supporting structure.

The switch must be installed with minimum NEMA 3R hardware for conduit connections.

To prevent switch contact distortion, level and plumb the enclosure.This can be done by placing washers between the switch enclosure and the mounting surface.

NEVER install the switch where any corrosive substance might drip onto the enclosure.

Protect the switch at all times against excessive moisture, dust, dirt, lint, construction grit and corrosive vapors.

A typical installation of the Automatic Power Transfer Switch is depicted in Figure 2. It is best if it is mounted near the utility meter, either inside or outside. Discuss layout suggestions/changes with the owner before beginning the system installation process.
