Kohler GM17250 Transformer for Load Control Systems


The Kohler GM17250 Transformer, specifically the GM17250-KP1-QS model, is a vital component designed for residential and light commercial generator load management systems. This 400 amp transformer has a larger inner diameter, specifically tailored to fit applications using oversized cables. It fits perfectly with load control modules and load shed kit installations, ensuring reliable power distribution and enhancing safety.


Advanced Load Monitoring Technology


This device provides precise load monitoring functions through its 400:3 amp to VAC ratio. The larger inner diameter allows heavy-duty cables that many traditional transformers cannot manage. When paired with Kohler’s load control module or load shed kit, it encourages smart power management. This prevents generator overloads and ensures continuous operation of critical electrical services during backup power events.


Enhanced Cable Compatibility Design


The GM17250-KP1-QS stands out with its 57.2mm inner diameter opening, which is much larger than typical transformers. This design suits heavy-gauge conductors usually found in high-capacity electrical setups. Its compact 111.8mm outer diameter gives it a robust build, making installation easy inside residential transfer switch enclosures or commercial electrical panels.


Seamless Generator System Integration


Built for Kohler generator sets equipped with RDC2 and DC2 controllers, this transformer integrates well with load management systems. It constantly monitors electrical current and frequency to maintain optimal generator performance. The transformer transmits essential load data that supports dynamic load shedding, protecting sensitive electronics like computers and televisions from harmful frequency drops during generator use.


Professional-Grade Construction


The GM17250-KP1-QS is manufactured to comply with strict electrical safety standards. It includes an internal 16-ohm burden resistor for accurate signal conversion. With its rugged construction, it delivers reliable operation in both indoor and outdoor environments when installed correctly. This unit carries a UL listing and CSA certification, proving it meets North American safety regulations for both residential and commercial use.


Intelligent Load Management Applications


Used together with Kohler’s load control module, this transformer can manage up to six residential loads automatically. The system prioritizes essential circuits and temporarily disconnects non-critical loads during peak power demand. This intelligent load management helps homeowners and businesses run smaller, more cost-effective generator sets without sacrificing power to critical appliances.


How the Kohler GM17250 Transformer Works


The transformer measures the electrical current flowing through the primary service conductors. As current passes through the cable placed inside the transformer's inner diameter, a proportional voltage signal is induced based on the 400:3 ratio. The signal feeds the load control module, which continuously evaluates power use and generator capacity to guide real-time load shedding and restoration.


Installation Flexibility


The larger inner diameter design offers versatile installation options for multiple cable sizes. Electricians can conveniently install oversized or multiple conductors without facing space problems. The unit mounts easily within transfer switch enclosures or near distribution panels, providing accurate current measurement for monitored phases.

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.

Jacob B

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

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!
