About Generator Installation in Cambridge

Generator installation ranges from portable transfer switch setups to whole-home standby generators that start automatically during power outages. Standby generators connect to your electrical panel and run on natural gas or propane.

Typical costs: A transfer switch for a portable generator costs $500–$1,500 installed. Whole-home standby generators (Generac, Kohler) typically run $5,000–$15,000 fully installed including the concrete pad, gas line, and electrical connections.

Common projects include:
  • Whole-home standby generator installation
  • Transfer switch installation for portable generator
  • Generator maintenance and load testing
  • Natural gas line connection for generator
  • Commercial backup power systems

Standby generator installations require electrical permits and often gas or plumbing permits for the fuel line. Some areas also require noise or setback compliance.

Frequently Asked Questions

How much does generator installation cost in Cambridge?
A whole-home standby generator (14–22 kW) with automatic transfer switch typically costs $5,000–$15,000 installed. The unit itself is roughly half the cost — installation includes the concrete pad, gas line, electrical hookup, and permits.
How do I find a reliable generator installation contractor in Cambridge?
Choose an installer authorized by the generator manufacturer (Generac, Kohler, Briggs & Stratton). They should perform a load calculation to properly size the unit, not just recommend the biggest one. Ask about warranty terms and annual maintenance plans.
Do I need a permit for generator installation in Cambridge?
Yes — standby generators require electrical permits and typically gas or plumbing permits for the fuel connection. Your installer should handle all permit applications and coordinate inspections.
