About Capital Electric

Over forty years ago, Capital Electric began as an idea in the Harpster family garage, built on a foundation of traditional values and a commitment to fully personalized service. While a lot has changed since 1978, our dedication to these core principles remains unchanged.

As the industry has evolved, we’ve stayed at the forefront, ensuring our customers always have what they need to succeed. Today, we’re proud to be a family-owned, local wholesale distributor of industrial, electrical, and network/datacom products, serving a wide range of industries with certified expertise and innovative solutions.

Products

We are fortunate enough to partner with many of the world’s leading manufactures. We don’t distribute all brands, but the ones we do are best of the best, which allows us to sleep well and you to accomplish great things.

The team at Capital Electric has always been eager to help us out in any way they can from pricing projects big and small to supplying materials needed to complete our installations. If there’s any other way they can lend a hand, whether it be offering up resources to help with labeling a large project or assembling a product before it’s shipped, they’ll do it. They’re a great group of people who strive to make sure that what they do is always done right.
