If you already own a portable generator, you do not need to drag extension cords through windows to keep the fridge cold during a Huntsville outage. Huntsville Generator Pros installs manual transfer switches and code-compliant generator interlock kits, so the portable powers essential circuits safely and without backfeeding the utility line.
A portable generator hookup is a permanent electrical install that lets you plug a portable generator into a dedicated inlet on the side of the house. The inlet feeds either a manual transfer switch or a generator interlock kit on the main panel. When the grid drops, you wheel the portable outside, fire it up, plug it in, and flip the switch. Essential circuits stay on for the duration of the outage.
A manual transfer switch is a dedicated subpanel of selected circuits, usually six to ten, that can be swung from utility to generator power. It is the cleaner-looking option and forces you to pre-pick which circuits matter. A generator interlock kit is a sliding plate installed on the main panel that physically prevents the main breaker and the generator breaker from being on at the same time, so you can choose which circuits to run by flipping breakers. Interlocks are cheaper and more flexible; manual transfer switches are more foolproof.
The dangerous DIY pattern is the suicide cord: a double-male extension cord plugged into a wall outlet on one end and the generator on the other. That cord backfeeds power onto the utility line and can kill a Huntsville Utilities lineman working on what they believe is a dead circuit. Code-compliant interlocks and manual transfer switches make backfeed physically impossible. We will not install anything that does not meet this standard.
We size the inlet, the wiring, and the switch to your specific portable. A 5,000-watt portable does not need 50-amp service; a 12,000-watt portable does. We confirm the receptacle on the portable's panel during the site visit, then spec the inlet and wiring accordingly so everything plugs in cleanly when you need it.
Manual transfer switches and interlock kits both require electrical permits in Huntsville, even on existing panels. We pull the permit, schedule the inspection, and provide the paperwork. The inspection takes maybe 15 minutes and protects you at resale and on insurance claims.
