Why can I not just plug a generator into an outlet?

Backfeeding through an outlet energizes your whole panel and can push power onto the grid, which can kill a lineman. It is illegal and dangerous. A transfer switch or interlock isolates you safely.

Do you handle the gas line too?

We wire the electrical and coordinate with a licensed gas fitter for the fuel side. We keep the trades in sync so the install lands on schedule.

Why it does not pay to wait

When the grid drops in a Texas storm or freeze, an unprepared home loses heat, refrigeration, medical equipment, and the well pump if you have one. An improper generator hookup is worse: it can backfeed the line and electrocute a lineman. Waiting risks both comfort and a life.

Texas taught everyone a lesson about the grid. When the power drops, you want to flip to backup without dragging cords through a window or backfeeding a line and putting a lineman at risk. That is what a proper transfer switch is for.

We install standby generators on a pad with an automatic transfer switch, or we set up a portable-ready interlock so you can run the essentials safely. Either way it is permitted, code-right, and wired so nobody gets hurt.

What you can check yourself first

Before you call, here is what you can safely check on your own. Even if you still call us, you will walk in knowing more than you did.

Decide what has to keep running in an outage: fridge, heat, AC, well pump, medical gear.
Note whether you have natural gas, propane, or neither. That drives the generator type.
Find a spot outside, away from windows, where a unit could sit.
Never run a portable generator into a wall outlet. Ask us about a proper interlock or transfer switch instead.
