Generator Transfer Switches

Code-compliant generator hookups installed by a Master Electrician. Interlock kits, manual transfer switches, and automatic transfer switches for any generator setup. Licensed Master Electrician | Electrical Contractor TECL #31608.

Why You Need a Transfer Switch

A transfer switch is not optional. It is a code requirement (NEC Article 702) that prevents your generator from backfeeding power into the utility grid. Without one, you risk electrocuting linemen working to restore power — and it is illegal.

Some people try to backfeed through a dryer outlet or bypass the system entirely. This is how people die. A proper transfer switch creates a physical disconnect that makes it impossible for generator power and utility power to be connected at the same time.

Three Options

Interlock Kit

Most flexible. Best value.

A mechanical sliding plate installed on your main breaker that physically prevents the main breaker and generator breaker from being on at the same time. Allows you to power ANY circuit in your panel from the generator — not just pre-selected ones.

  • Powers your entire panel
  • Lowest cost option
  • Manual operation (flip breakers)
  • Load management (turn off big loads before switching)

This is what powers our $2,500 turnkey package.

Manual Transfer Switch

Subpanel with pre-selected circuits.

A separate subpanel installed next to your main panel with 6-10 pre-selected circuits. When the power goes out, you flip a single lever to switch those circuits to generator power. Simpler operation, but only covers the circuits wired into the subpanel.

  • One-switch operation
  • No load management needed
  • Only covers selected circuits
  • Higher cost than interlock

Automatic Transfer Switch

For standby generators only.

Installed with a permanent standby generator. Senses utility power loss, starts the generator, and transfers power automatically. No human action required. The most expensive option, but the only one that works when you are not home.

  • Fully automatic operation
  • Works when you are away
  • Requires standby generator
  • Highest cost option

What's Included in a Generator Hookup

50-Amp Power Inlet Box

Weatherproof exterior inlet where you plug in the generator cord. Rated for outdoor use.

Interlock Kit or Transfer Switch

Code-compliant disconnect installed on your panel. Brand-matched to your panel manufacturer.

25ft 50-Amp Generator Cord

Heavy-duty locking cord (L14-50 or CS6375) to connect your generator to the inlet box.

Load Management Training

We walk you through which breakers to manage so you don't overload your generator. Hands-on training included.

Already Have a Generator?

We install generator hookups separately from our turnkey package. If you already bought a portable generator and just need it safely connected to your panel, we can do that. We will assess your panel, install the inlet box and interlock, and walk you through safe operation — all code-compliant and inspected.

Never Backfeed Through a Dryer Outlet

Backfeeding through an appliance outlet is illegal and deadly. It sends power back through the utility lines and can kill linemen working to restore electricity. A code-compliant transfer switch or interlock is not optional — it is a life safety requirement.
