Transfer switch RSS

residential

Description

The RSS Automatic Transfer Switch combines

dependability and flexibility in a small, economical

package. RSS switches are suitable for standby power

systems in residential and light commercial applications.

The RSS100 and RSS200 products are built to satisfy the

back up power requirements of virtually any residential or

light commercial application.

The RSS residential products are Listed to UL 1008, the

Standard for Transfer Switch Safety. Cummins Onan

residential products adhere to National Electrical Code

(NEC) and National Fire Protection Association (NFPA)

requirements.

RSS transfer switches monitor utility power 24 hours a

day and 7 days a week. When utility power becomes

unsatisfactory or fails; the controller signals the generator

to start, then transfers the load. When stable utility

voltage returns, the transfer switch will automatically

switch electrical load from the generator to the utility. No

action is required by the home owner.

All switches are UL 1008 Listed with UL Type

Rated cabinets and UL Listed CU-AL

terminals.

All switches are certified to CSA C22.2 No.

178 up to 120/240 VAC.

All switches comply with NEMA ICS 10.

All switches comply with NFPA 70, 99 and

110.
