A Midwest Hub for Electrical Excellence

We Are Rooted With History

J&M Electrical Supply opened its doors in 1973 with Lester Jarvis, Jr. at the helm of the operation. Officially headquartered in Cambridge, Ohio since day one, our family-owned company has become the go-to distributor of electrical and lighting supplies to job sites within a 60-mile radius – and many other companies throughout the United States. We provide full-service electrical distribution to contractors and end users within the commercial and industrial realms. Our team prides itself on its ability to grow with the industry. While new technologies come to be and innovative strategies surface, we stay on top of our game to best serve our clients.


As we push forward, our team does so with more than just the same consistency, delivery and dependability that it has provided for more than 40 years. J&M Electrical Supply will head into a new era of industrial electric supply with an educated eye toward Green design and sustainability. Our energy audit services and ecoInsight partnership are a testament to our constant drive to provide your operation with the most energy efficient supply options possible. We use our years of expertise and repertoire of relevant software to your advantage.


Cambridge may appear to be just a humble small town in Ohio, but it serves as a strategic location for markets with an immense need for electric supplies and tools. Our facilities are located 80 miles east of Columbus, 107 miles west of Pittsburgh and 122 south of Cleveland. While this placement allows for convenient deliveries, pick ups and drop offs, we have adapted to the need for further service by developing a reliable network of 3PL shippers and logistics partners. Have a project outside of our typical radius? Does your job site lack a physical address? It doesn’t matter. We will get your supplies to you – no matter the circumstances!
