Generator Installation in Alexandria, TN
Storm-related outages are a regular part of life around Center Hill Lake, which is why so many Alexandria, TN homeowners choose to install a standby or portable generator system. Center Hill Electric Co. wires generator installations with a properly rated transfer switch, never a makeshift extension cord setup.
Whether you're installing an automatic standby generator that kicks on within seconds of an outage or wiring a transfer switch for a portable unit, we size the system to the circuits that actually matter most during an outage.
Generator Installation You Can Rely On in Alexandria, TN
A generator without a transfer switch is a genuine hazard — backfeeding power into a de-energized grid line can injure utility workers and damage your home's equipment. We install manual or automatic transfer switches that isolate your home from the grid the moment the generator kicks in, eliminating that risk entirely.
For automatic standby generators, we wire the unit to a dedicated transfer switch and, where appropriate, a sub-panel covering your essential circuits: well pump, refrigerator, sump pump, and HVAC, so the system starts automatically within seconds of an outage.
For portable generators, we install a properly rated inlet box and manual transfer switch, giving you a safe, code-compliant way to power key circuits without running extension cords through a window or door.

Frequently Asked Questions
Do I really need a transfer switch for a portable generator?
Yes. Without a transfer switch, backfeeding a generator into your home's wiring can energize utility lines and injure workers, in addition to damaging your equipment. It's required by code for a reason.
What's the difference between standby and portable generator installation?
A standby generator is permanently installed outside and starts automatically during an outage; a portable generator is wheeled out and connected manually through an inlet box and transfer switch.
Can a generator power my whole house?
It depends on the generator's size; we run a load calculation to determine whether your whole home or just essential circuits can be covered, and size the transfer switch accordingly.
Do you install the generator itself, or just the electrical connection?
We handle the electrical scope — transfer switch, wiring, and sub-panel — and can coordinate directly with your chosen generator installer or supplier.
How long does generator installation take?
A transfer switch and inlet box for a portable generator is usually a one-day job; automatic standby systems typically take one to two days depending on sub-panel work.
