Portable Generator Hookup with Manual Transfer Switch Service in the Taunton-Raynham Metro Area
A manual transfer switch is one of the safest and most efficient ways to connect a portable generator to your home. Rather than relying on extension cords or unsafe DIY solutions, a transfer switch allows you to power key circuits directly from your generator with a simple flip of a switch.
Our team specializes in portable generator hookup services using manual transfer switches, ensuring your setup is both code-compliant and convenient. You can choose the circuits you want to power—such as the fridge, sump pump, or furnace—and we take care of the wiring and testing, so you’re ready when an outage strikes.

Generator Interlock Kit Installation Safety in Bristol & Plymouth Counties
If you prefer a more flexible solution, a generator interlock kit might be the answer. This device connects your portable generator to your home’s electrical panel, preventing simultaneous use of utility and generator power and keeping linemen and your equipment safe.
While more affordable than a transfer switch, an interlock kit must be installed with care to comply with electrical codes. Our licensed electricians are experienced in generator interlock kit installation and will ensure everything is labeled, tested, and safe for use during an emergency backup power event.
