Description

The Service Entrance RSS Automatic Transfer Switch is

integrated with the RS12000 genset. The Service

Entrance RSS residential products are Listed to UL 1008,

the Standard for Transfer Switch Safety. The switch and

genset combination is specifically designed for a

simplified, quicker installation.

These UL 1008 Service Entrance rated RSS Switches are

suitable for standby power systems in residential and

light commercial applications. The Cummins Onan

automatically switch electrical load from the generator to

the utility. No action is required by the home owner.
