Cummins Power Generation RSS100-6634 Details and Specifications

Cummins Onan RSS100-6634 100 Amp Automatic Transfer Switch

The RSS Automatic Transfer Switch combines the dependability and flexibility in a small, economical package.  RSS swtiches are suitable for standby power systems in residential and light commercial applications. 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 utility.  No action is required by the home owner.

  1. We trust in this company

    Posted by Anita T on 8th Dec 2011

    Norwall is by far the cheapest company to buy generators from online while still being legit and honest about their products. Not only did we get free shipping but no tax either. There is quite a big difference between their price and other companies. Norwall must be doing something right when their prices, customer service, and generators are all harmony. This is a great generator and we love it. Thanks.
