INTRODUCTION

INTRODUCTION

ASCO Series 165 Automatic Transfer Switches are Listed under the Underwriter’s Laboratories Standard for Transfer Switch Equipment, UL–1008. They are intended for use only in optional standby systems in accordance with the National Electrical Code, NEC/NFPA 70, Article 702.

This automatic transfer switch is intended for standby power applications in residential or light commercial use only.

!

The Series 165 Automatic Transfer

Switch is not for emergency or

life–support systems.

This product is not intended for emergency or life–support systems.

If you have more stringent application requirements contact ASCO for other products suitable for critical applications.

The automatic transfer switch helps provide safe connection of the alternate source (generator) to the electrical load after disconnecting the preferred source (utility). It contains a double–throw, electromechanical switching device for inherent isolation of the preferred and alternate sources. This isolation prevents the danger of connecting the utility to the generator which could cause damage or personal injury. The automatic transfer switch’s digital controller provides continuous monitoring of both power sources and a start/stop signal to the generator.
