Why do Fort Pierce homeowners install a generator?
Fort Pierce loses power in storms — hours from a summer thunderstorm, days from a hurricane. A generator does not stop the outage. It gives you power while it lasts. A small portable generator can run a refrigerator, a few lights, and a phone charger. A large standby generator can run the whole house, including the air conditioner. Tell us what you need to keep running when you call. That is where the sizing starts.
What is backfeeding, and why is it so dangerous?
Backfeeding is when a generator sends power back through your house wiring and into the utility lines outside — for example, with a cord plugged into a dryer outlet, or wired straight into the panel with no transfer switch or interlock. It can kill a utility worker on a line that should be dead. It can also destroy your generator, damage appliances, and start a fire. Never backfeed, and never plug a generator into a wall outlet. If you are not sure how yours is connected, call us. A service call and diagnosis is typically $150 to $400, checked November 9, 2026.
How does a portable generator with an inlet and interlock work?
This is the simplest proper hookup, and the lowest-cost way to power part of your house. We install a weatherproof inlet box outside, wired to your panel, and an interlock on your panel — a plate that makes it impossible to turn on the generator breaker while the main breaker is on, and vice versa. In an outage, roll the generator outside, plug a heavy cord into the inlet, start it, turn off the main breaker, slide the interlock, and turn on the generator breaker. You cannot run everything at once: turn on the refrigerator, a few lights, and the outlets you need, and leave the air conditioner, water heater, and dryer off, unless the load calculation says otherwise. The inlet and interlock is typically $500 to $2,400, not including the portable generator itself.
How does a manual transfer switch work?
A manual transfer switch feeds a smaller set of circuits — a subpanel — from the generator. We install a subpanel with the circuits you want to keep running: refrigerator, some lights, some outlets, the router, and sometimes a small window air conditioner. In an outage, plug in the portable generator, start it, and flip the transfer switch. The subpanel now runs on generator power; the rest of the house stays off. A manual transfer switch with a subpanel is typically $1,500 to $2,500, checked November 9, 2026, not including the portable generator. A subpanel on its own is typically $800 to $2,000.
How does a standby generator work?
A standby generator is permanent, installed outside on a concrete pad, wired into your system, and connected to a fuel supply. It starts by itself when power goes out, and stops by itself when power comes back on. An automatic transfer switch watches the utility power, starts the generator, and switches the house to generator power, then switches back when utility power returns. A standby generator, 11 to 14 kW, is typically $6,500 to $9,500. A whole-home standby generator, 18 to 24 kW, is typically $9,500 to $18,000, checked November 9, 2026, for the generator, transfer switch, and installation. We price in writing after seeing the job.
What size generator do I need?
Size is a load calculation, not a guess. We add up what you want to run at the same time: refrigerator, lights, charger, router, then air conditioner — which draws a large surge when it starts — plus water heater, dryer, pool pump, or stove. A 11 to 14 kW standby generator can carry the essentials and often one air conditioner. A 18 to 24 kW unit can carry a whole home in many Fort Pierce houses. Many homes built in the 1970s and 1980s have 100-amp panels, or older panels that are full, rusted, or Federal Pacific or Zinsco. A generator hookup may need panel work first.

What fuel does a generator use, and where should it go?
Portable generators most often run on gasoline, which goes stale — a generator that has sat for a year may not start when you need it. Keep fuel fresh, run it regularly, and store fuel safely, away from the house. Never store gasoline inside the house. Standby generators most often run on natural gas or propane. If your house has no gas supply, a propane tank is needed. Gas work, tank, and piping are separate from our electrical price.
A portable generator goes outside, on dry ground, at least 20 feet from the house where you can, with exhaust away from windows, doors, and vents. Never run it in a garage or on a covered porch. Generators make carbon monoxide, which has no smell and no colour, and kills. A standby generator goes outside, on a concrete pad, with clear space for air flow and service.
Do I need a permit for a generator?
Yes, in most cases. The permitting authority is the City of Fort Pierce inside city limits, and St. Lucie County outside the city. We pull the permit where one is needed. Straightforward electrical permits are often plan-checked in one to two weeks, but that is a secondary source and we do not promise a timeline. [VERIFY] The exact code edition is a question for the permitting authority at the time of the permit. [VERIFY]
How does installation work?
Step 1: What do you need to run?
We ask what you need to keep running — refrigerator, air conditioner, lights, medical equipment, home office. That decides the size and type.
Step 2: Load calculation and panel check
We do a load calculation and check the panel, meter, and wiring for room and condition. If it is old, full, or a Federal Pacific or Zinsco panel, we will tell you what needs to happen first.
Step 3: Choosing the type, permit, and placement
We tell you which option fits, pull the permit, agree the placement, and confirm the fuel supply for a standby unit.
Step 4: Installation and testing
We install the inlet, interlock, transfer switch, or standby generator, test it, and switch the house over and back. We show you how it works. Call Now to Speak to a Specialist — [PHONE]. We respond fast — just a call away.
What does generator installation cost?
We give you a price in writing after we see the job.
How do I use a generator safely in a hurricane?
Use it only outside, away from the house, with exhaust away from windows and doors. Never run it in a garage or porch, or inside the house. Never refuel a hot generator — let it cool first. Keep fuel in approved containers, outside, away from ignition sources. Do not overload it: run only the circuits the load calculation allows. Do not connect a generator without an interlock or transfer switch. That is backfeeding. After a storm, if a panel or outlet has been under water, do not turn it on. Call us first. If there is a downed power line, stay away, and call 911 and your utility. Read more: FPUA vs FPL in Fort Pierce
When should I call an electrician, and when should I call the utility or 911?
Call 911 first if there is fire, if anyone is hurt, or if someone has carbon monoxide symptoms — headache, dizziness, nausea — after a generator has been running. Get out into fresh air. Call your utility if power is out on the whole street, or if a power line is down. Call a licensed electrician at [PHONE] if you want a generator installed, if you are not sure your hookup is safe, or if your generator trips or will not start. If you smell burning or see sparks, call [PHONE] now. Read more: Emergency Electrician in Fort Pierce

Frequently asked questions
Can I plug my generator into a dryer outlet?
No. That is backfeeding. It can kill a utility worker, destroy your generator, and start a fire. Use an inlet with an interlock, or a transfer switch.
What size standby generator do I need?
It depends on the load calculation. A 11 to 14 kW unit can carry the essentials and often one air conditioner. A 18 to 24 kW unit can carry a whole home in many Fort Pierce houses.
How long will a portable generator run?
It depends on the tank, load, and generator. A portable generator on gasoline runs for hours on a tank, not days. A standby generator on gas or propane can run much longer.
Do I need a permit for a generator inlet?
In most cases, yes. The permitting authority is the City of Fort Pierce inside city limits, and St. Lucie County outside the city.
Can a generator run my whole house?
A large standby generator can, if the load calculation says so. A portable generator cannot run everything at once — not the air conditioner, water heater, and dryer all at the same time.
What if my panel is old?
Many Fort Pierce homes built in the 1970s and 1980s have panels that are full, rusted, or Federal Pacific or Zinsco. A generator hookup may need panel work first.
