The Supco EC10 terminal repair kit is designed for use in compressors up to 5 horsepower. It includes spade connectors and fully insulated terminal connectors. The kit contains three 10-American Wire Gauge (AWG) wires, each measuring 3 feet in length. No tools are required for the installation process.

Relay switches, also known as electrical relays or electrical relay switches, utilize a small amount of power to control a larger source of power connected to electrical devices such as car motors, computers, and lighting installations. A basic relay switch comprises a control circuit with an electromagnetic coil and a load circuit with contacts and a lever. When current flows into the relay switch, it moves through the coil, creating a magnetic field that causes the lever in the load circuit to move between contacts, either turning the device on or off.

In a normally open (NO) relay switch, when power is supplied to the relay, the load circuit is closed, and the power source connected to the relay is turned on. In a normally closed (NC) relay switch, when power is supplied to the relay, the load circuit is open, and the power source connected to the relay is turned off. In other types of relay switches, non-moving parts such as transistors or semiconductors can be used as the control circuit to operate the switching mechanism.

Relay switches can be controlled with an external switch, such as a light switch, or they can be connected to an automatically switched power source, such as a car ignition. One relay can operate multiple switches, and multiple relays can be operated with a single switch, with each relay operating independently from the other relays in the system.

Supco, a company founded in 1945 and headquartered in Allenwood, New Jersey, manufactures test instruments and replacement parts for heating, ventilation, air conditioning, and refrigeration systems.
