Generator Connections & Backup Power

Generator interlock and transfer switch installation for portable backup power, plus electrical connections for whole-home standby systems in St. George and Southern Utah. We help match the setup to your panel, the loads you care about, and your generator.

Portable Generator Interlock & Transfer Switch Installation

Start with the loads you want available during an outage. We’ll review your panel, generator capacity, and installation requirements before recommending an approach.

Portable generator + interlock kit

A panel interlock pairs a compatible breaker arrangement with an exterior generator inlet. You connect and start the portable generator, then select loads manually.

  • Panel compatibility and load planning
  • Interlock, inlet, and dedicated wiring
  • Manual operation during an outage

Portable generator + manual transfer switch

A manual transfer switch routes selected circuits to a portable generator. It gives you a defined set of priority loads to power when you operate the switch.

  • Priority circuit selection
  • Transfer switch and inlet installation
  • Manual changeover and system testing

Whole-home standby generators

A permanently installed standby generator with an automatic transfer switch can detect a utility outage and transfer supported loads to generator power. We plan the electrical connection and transfer equipment around your service and power needs.

Whether you want essential circuits or broader home coverage, the generator size and load design determine what can run at once. We can coordinate electrical work with the equipment and fuel installation teams as needed.

  • Automatic transfer switch installation
  • Service and load assessment
  • Generator electrical connections
  • Startup, testing, and inspection coordination

What happens next

We assess your electrical service and the loads you want to support, then recommend equipment and a connection method. After installation, we test the transfer setup and coordinate the required permit and inspection.

Portable generators must be placed and operated according to the manufacturer’s instructions, including outdoor ventilation and a suitable fuel supply. We’ll show you how your installed transfer equipment is intended to operate.

Generator questions, answered

These are the details we talk through before choosing equipment or scheduling installation.

Interlock kit or manual transfer switch: which is right for me?

An interlock can let you select panel circuits within the generator’s capacity when your panel supports an approved kit. A manual transfer switch routes a planned set of priority circuits. We review the existing panel and your outage priorities before recommending either option.

Can a portable generator run my entire house?

That depends on the generator’s output and the loads you use at the same time. Many households prioritize refrigeration, some lighting, internet, and selected heating or cooling equipment. We can help plan a connection around realistic capacity rather than promise every circuit will run.

Will a standby generator turn on automatically?

A properly configured standby system detects utility loss and, through its automatic transfer switch, supplies the circuits included in the design. Actual coverage depends on generator sizing and load management.

What affects installation cost?

The existing panel and service, generator capacity, inlet location, length of wiring runs, transfer equipment, and permit requirements all affect the scope. We’ll review the site and explain the options before quoting work.

Can you connect a generator I already own?

We can assess its output and connector, your panel or service, and the circuits you want to support. Bring the model information to the appointment so we can confirm a compatible connection.
