Review GENERAC Harness Kit

The Generac OK6781A Harness Kit is a crucial accessory for anyone looking to install or maintain a Generac automatic transfer switch (ATS) system. This harness kit is specifically designed for use with Generac's GP Series and GPX Series air-cooled generators, and it simplifies the wiring process between the generator and the transfer switch.

The OK6781A Harness Kit comes with an impressive range of components, ensuring a comprehensive solution for various wiring requirements. The kit includes a generator harness, a transfer switch harness, and a neutral bus bar. These components are engineered to meet the highest standards of quality and durability, with heavy-duty insulation and high-strain wiring capable of withstanding the rigors of continuous use.

The generator harness features a numbered and color-coded system for easy identification and connection of the individual wires. Each wire is securely terminated with a connector that can be easily attached to the corresponding terminal on the generator. The harness also includes a ground cable with a grounding clamp, ensuring a safe and secure connection to the ground rod.

The transfer switch harness offers a similar level of convenience and functionality. Each wire in the harness is numbered and color-coded to correspond with the wiring diagram on the transfer switch. The harness includes a main breaker disconnect wire, as well as a ground cable with a grounding clamp for the transfer switch.

The neutral bus bar is an essential component of the harness kit, providing a central connection point for the neutral wires from the generator and the transfer switch. The bus bar is made of heavy-duty copper and is designed to ensure a reliable and efficient transfer of power between the two components.

Overall, the Generac OK6781A Harness Kit offers a convenient, efficient, and safe solution for wiring a Generac generator to an automatic transfer switch system. Its heavy-duty components and color-coded wiring make installation and maintenance simple and straightforward, ensuring that your power system is always ready to keep your home or business running smoothly.
