Professional Interlock Installation - The Smart Backup Power Solution
An interlock kit transforms your portable generator into a safe, code-compliant whole-house backup power system. For a fraction of the cost of automatic standby generators, you get reliable backup power that can run all the lights and outlets in your home.
This isn't a DIY extension cord solution. It's a professional, permanent installation that safely connects your generator to your electrical panel, allowing you to power any circuit in your home during an outage.
How Generator Interlock Kits Work
An interlock kit is a mechanical device that ensures your main breaker and generator breaker cannot be on simultaneously. This prevents dangerous backfeeding that could injure utility workers or damage equipment.
The System Components
- Interlock plate: Mechanical sliding plate installed on your panel cover
- Generator inlet box: Weatherproof 30 or 50-amp connection mounted outside
- Generator breaker: New breaker in your panel for generator input
- Heavy wiring: 6 or 8 AWG copper from inlet to panel
- Connection cable: 50-amp cord from generator to inlet (sold separately)
Step-by-Step Operation During Power Outage
- Verify outage: Check neighbors to confirm utility outage
- Position generator: Roll out to safe location (20+ feet from house)
- Start generator: Let warm up for 2-3 minutes
- Connect cable: Plug into generator and inlet box
- Turn off main breaker: Disconnects from utility
- Slide interlock plate: Allows generator breaker to turn on
- Turn on generator breaker: Powers your panel
- Manage circuits: Turn on breakers for needed circuits
Tri-Fuel Generators We Recommend and Supply
50-Amp Tri-Fuel Generators We Supply
We supply and recommend tri-fuel generators that operate on gasoline, propane, or natural gas:
- Power output: 9,500-12,000 starting watts
- 50-amp capability: Powers all lights and standard outlets
- Electric start: Key fob remote starting
- Runtime: 8-12 hours on gasoline, unlimited on natural gas
- Noise level: 72-74 dB at 23 feet
Natural Gas Connection Option
We coordinate with licensed gas contractors to install quick-disconnect fittings for natural gas operation. This eliminates refueling during extended outages - your generator runs as long as the gas flows. Contact for details.
Using Your Existing Portable Generator

- Minimum 30-amp output (7,500 watts)
- L14-30 or L14-50 outlet
- Floating neutral or bonded neutral compatible
- Good working condition
