Section 1 — General Information RTS “HS” Type Transfer Switch

1.1 INTRODUCTION

This manual has been prepared especially for the purpose of famil iarizing personnel with the design, application, installation, opera tion and servicing of the applicable equipment. Read the manual carefully and comply with all instructions. This will help to prevent accidents or damage to equipment that might otherwise be caused by carelessness, incorrect application, or improper procedures.

Every effort has been expended to make sure that the contents of this manual are both accurate and current. The manufacturer, however, reserves the right to change, alter or otherwise improve the product at any time without prior notice.

1.2 EQUIPMENT DESCRIPTION

The automatic transfer switch is used for transferring electrical load from a UTILITY (NORMAL) power source to a EMERGENCY ( STANDBY) power source. Such a transfer of electrical loads occurs automatically when the UTILITY power source has failed or is substantially reduced and the EMERGENCY source voltage and frequency have reached an acceptable level. The transfer switch prevents electrical feedback between two different power sources (such as the UTILITY and EMERGENCY sources) and, for that rea son, codes require it in all standby electric system installations.

The transfer switch consists of a transfer mechanism, a relay con trol, and a terminal strip for connection of sensing wires.

This switch is suitable for control of motors, electric discharge lamps, tungsten filament and electric heating equipment and the tungsten load does not exceed 30% of the switch rating.

The transfer switch is for use in optional standby systems only.

A 100A rated switch is suitable for use on circuits capable of delivering not more than 10,000 RMS symetrical amperes, 250 VAC maximum, when protecty by a 100A maximum circuit breaker (Siemens types QP or BQ) or 150A maximum circuit breaker (Square D Q2, Westinghouse CA-CAH, General Electric TQ2 and Siemens QJ2).

A 200A rated switch is suitable for use on a circuit capable of 10,000 rms symmetrical amperes, 240 VAC when protected by a circuit breaker without an adjustable short time response or by fuses.

1.3 TRANSFER SWITCH DATA
