Established in 1982, HLC Electric Supply Co. has a long-standing history that goes back even further. In the 1950s, Charley and Art Contreras, two brothers, started a company named Industrial Marine, dedicated to servicing and reselling industrial electrical equipment. For over twenty years, in an era known as the golden age of electricity, these brothers supplied an alternative for electrical distribution and motor control equipment when manufacturers fell behind the rapid industrial growth. A significant number of these systems continue to function today. Three generations on, HLC Electric is proud to serve our community and customers throughout the nation, utilizing the rich knowledge and experience our history has provided in electrical systems. From the 1950s through today and into the future, HLC has the strength to keep YOUR power flowing!

Recommended Customer Reviews

The best! On time and Charlie was sooo friendly and helpful. Very knowledgeable and found/fixed our problems very quickly. Reasonable rates. Can't say enough good about Charlie and the service he provides. Can't find people like this these days who go beyond the call. Would definitely use HLC/Charlie again, and recommend them to anyone who needs electrical service. Thank you, Charlie!

Margaret and Charlie job well done!! Very polite and friendly people would recommend this location if you are in need of electrical supplies.

We were looking for an older breaker cover for our breaker box and most places don't carry it anymore. Who carries parts for Pushmatic circuit breakers in this day and age? After looking around several hardware and electrical supply stores, one of them recommended HLC to us. The place isn't very easy to find and the warehouse is hard to navigate through on your own, but they carry a wide variety of used older breaker switches, covers and other parts. The staff was helpful and he helped locate the exact part we were looking for. Buying parts in bulk will give you a better deal on parts, but if you aie looking for rare parts, give them a try!
