Demolition / Take Out Services

We pay CASH for your electrical equipment! Do you have equipment that needs to be removed or demolished? Relectric Supply can provide or coordinate removal and/or pick up of your surplus material. Because one of our primary goals is to salvage and recycle usable electrical systems, we will be glad to consider your materials. We also purchase materials that have already been removed.

Relectric Supply offers full reconditioning for most low and medium voltage electrical distribution and control products. We can repair or replace parts from most major manufacturers - new and obsolete. Our reliable engineers will assess, repair, and certify the condition of your equipment and provide a full 1 year warranty on systems we repair or replace.

Rental Equipment

We want to keep your power on. If your supplier has put an item on backorder with an unacceptable lead time, don't worry. We may be able to offer you rental equipment to get your system operational immediately. Our rental equipment is pulled from our normal inventory, so you can rest assured that any product you rent will adhere to the same quality standards as the items we sell, backed by our full 1 year warranty.

Equipment Testing

At Relectric Supply, we utilize the industry's newest technology to accurately test and generate test reports for all of our products.

If you have electrical equipment that you need tested for functionality, our skilled technicians can provide you with accurate results and a quick turn-around time. We can provide test reports that detail full conformance to original factory specifications, and where possible, we will provide a comparison of injection test results to factory guidelines.
