Product Overview

The Cummins RSS100 100 Amp NSE (Non-Service Entrance) 240V 1-phase Automatic Transfer Switch (ATS) delivers reliable backup power for homes and light commercial sites. This compact unit handles 100 Amps of continuous load without requiring service entrance ratings. It ensures seamless switching between utility and generator sources during grid failures. The automatic transfer functionality protects critical systems by maintaining uninterrupted service. Its design prioritizes efficiency and reliability for residential energy needs. Homeowners trust this switch for its UL 1008 listing and NEC compliance. The compact footprint allows easy integration into smaller electrical spaces. It pairs perfectly with Cummins backup generators for optimal performance.

Key Benefits

Seamless Power Transfer: Automatically switches loads between utility and generator power during outages without user intervention.

Compact Design: Features a small footprint that fits easily into limited spaces for residential and light commercial installations.

Non-Service Entrance Rated: Ideal for installations downstream of the main service panel where service entrance rating is not required.

24/7 Utility Monitoring: Continuously monitors utility power quality to detect unsatisfactory voltage or frequency conditions instantly.

Code Compliant Safety: UL 1008 listed and NEC compliant to ensure safe installation and operation per national standards.

How It Works

The Cummins RSS100 ATS operates as an open transition transfer switch for standby power systems. It monitors utility power continuously to detect failures or voltage anomalies. When utility power fails, the controller signals the generator to start automatically. Once the generator reaches stable voltage, the switch transfers the electrical load to the generator source. This process requires no action from the user. When utility power returns to stable levels, the switch automatically retransfers the load back. The system then allows the generator to cool down before shutting off. This cycle ensures continuous power availability during grid disruptions.

Utility Power Monitoring: The controller checks voltage and frequency 24 hours a day and 7 days a week. It identifies unsatisfactory power conditions immediately to trigger the backup sequence.

Break-Before-Make Action: The mechanism uses independent break-before-make action for 2-pole single phase switches. This prevents simultaneous closing of normal and emergency contacts to avoid short circuits.

Mechanical Interlock: A powerful solenoid drives the mechanically interlocked contactor mechanism. This interlock physically prevents both normal and emergency contacts from closing at the same time.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

Highly Recommend

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Keith S

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

Coll A

Great Experience

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
