Thomas & Betts

These Interlock Kits are custom designed for the Thomas & Betts electrical panels shown below – and made right here in the USA.

In addition to helping you to get more use and convenience out of your generator, these Kits are easier to install than traditional transfer switches; as a result, your local electrician should charge less for installation.
