Home Generator Installation in Northern New Jersey
Keep your lights, heat, refrigeration, and essentials running through every outage with a properly sized Generac or Kohler home standby generator, professionally installed and permitted by Vaccarella Electrical Services.
Service Overview
What Is Home Generator Installation?
A home standby generator is a permanently installed backup power system that turns on automatically within seconds of a utility outage, running your home on natural gas or propane until grid power is restored. Vaccarella Electrical Services handles the complete installation — load assessment, generator sizing, transfer switch wiring, gas connection coordination, permitting, and final inspection — so your family is protected the moment the next storm hits. We install both Generac and Kohler home generators for homeowners throughout Bergen County and Northern New Jersey.
Benefits
Reasons to Consider Home Generator Installation
Automatic Backup Power
An automatic transfer switch detects outages and starts your generator in seconds — no extension cords, no manual switching, no scrambling in the dark.
Whole-Home Comfort
Properly sized, a standby generator runs your furnace, refrigerator, well pump, lights, medical devices, and electronics so life continues normally during an outage.
Runs on Natural Gas or Propane
Connected to your existing gas line or a propane tank, your generator runs for days or weeks without refueling — far safer and more convenient than portable gas units.
Increases Home Value
A professionally installed standby generator is a desirable upgrade that adds resale value and signals a well-maintained, resilient home.
Permits & Inspections Handled
We pull every town permit and coordinate the electrical inspection, so your installation is legal, insurable, and fully code-compliant.
Expert Generac & Kohler Installation
As experienced installers of both leading brands, we size and match the right generator to your home and budget — not just the unit we sell.
Who May Need This Service?
Is Home Generator Installation Right for You?
Home generator installation is ideal for Northern NJ homeowners who want uninterrupted power during storms, grid failures, or planned outages. You'll benefit most if you rely on a furnace or sump pump, keep refrigerated food or medication, work from home, have well water or a septic pump, use medical equipment, or simply want the peace of mind that comes with never being left in the dark. If you've ever lost power for more than a few hours — or worried about the next one — a standby generator is a smart investment.
What to Expect
The Home Generator Installation Process
Your project begins with a free on-site assessment where we evaluate your home's electrical load, fuel source, and ideal generator location. We then recommend the right Generac or Kohler unit and transfer switch, provide a clear upfront estimate, and schedule installation. On install day our licensed electricians set the generator pad, connect the gas line (coordinated with your plumber or utility), wire the automatic transfer switch to your panel, and test the full system under load. We obtain the electrical permit and arrange the town inspection, then walk you through operation and maintenance so you're ready for the next outage.
Every home and project is unique. Your specific plan will be personalized during your free consultation with our team.
Choosing the Right Home Generator
Sizing is the most important part of a standby generator installation. Too small and it won't carry your essential loads; too large and you've overspent on capacity you'll never use. We calculate your home's starting and running watts — accounting for motor-driven appliances like air conditioners, furnaces, and well pumps that demand a surge at startup — and recommend a generator with the right kilowatt (kW) rating.
Air-Cooled vs. Liquid-Cooled
Most homes are well served by an air-cooled standby generator in the 14–22 kW range, which can manage essential loads or an entire smaller home. Larger homes with multiple HVAC zones, electric heat, or heavy loads may benefit from a liquid-cooled unit, which offers higher output and longer runtime durability.
Generac vs. Kohler
Both are dependable, nationally supported brands. Generac offers a wide range of sizes at a strong value and is the most popular choice for residential backup power. Kohler is prized for quiet operation and premium build quality. We're experienced installing both and will help you choose based on your home, budget, and preferences — never on a sales quota.
The Transfer Switch
The automatic transfer switch (ATS) is the brains of the system. It monitors utility power, signals the generator to start, and safely switches your home onto generator power — then back to the grid when power is restored. We size and install the transfer switch to match your panel and the loads you want covered.

Frequently Asked Questions
Home Generator Installation FAQs
Cost depends on the generator size, fuel source, transfer switch, and installation specifics. Most whole-home standby installations fall between $7,000 and $15,000 including the unit, transfer switch, wiring, permits, and labor. We provide a free, fixed-price quote after assessing your home.
It depends on what you want to power. We calculate your essential loads — furnace, refrigerator, well pump, lights, and key circuits — and recommend a kW rating that covers them with comfortable headroom. Whole-house coverage typically calls for a 20–26 kW unit; essential-load coverage can be handled by a smaller, more affordable generator.
If your street has natural gas, it's usually the simplest and most economical fuel — no refueling and unlimited runtime. If gas isn't available, propane is an excellent alternative; we'll coordinate tank sizing with your propane provider so you have enough fuel for extended outages.
Yes. We pull the required electrical permit from your town and schedule the inspection, so your installation is legal, insurable, and code-compliant. You don't have to deal with the municipality at all.
Most residential standby generator installations are completed in one to two days, depending on site prep, gas connection, and transfer switch wiring. We'll give you a clear timeline with your estimate.

Understanding Your Options
Home Generator Installation Glossary
Key generator and electrical terms used on this page, explained in plain language so you can feel confident about your project.
Home Standby Generator
A permanently installed backup power system that sits outside the home and turns on automatically within seconds of an outage. Connected to your home's electrical panel and fueled by natural gas or propane, it runs until utility power is restored.
Automatic Transfer Switch (ATS)
The device that senses a utility power outage, signals the generator to start, and safely switches your home from grid power to generator power — then back again when power is restored, without any manual action.
Kilowatt (kW)
The unit used to measure a generator's power output capacity. Proper sizing matches the kilowatt rating of the generator to the total electrical load your home needs to keep running during an outage.
Essential Load
The critical circuits and appliances a generator is sized to keep running during an outage — typically the furnace, refrigerator, well pump, lights, and a few outlets. Smaller generators can manage essential loads rather than the whole house.
Air-Cooled Generator
A standby generator that uses a fan to cool its engine. Common and cost-effective for most homes, air-cooled units typically range up to around 22 kW and are ideal for typical residential backup power.
Liquid-Cooled Generator
A larger standby generator that uses a liquid coolant system (like a car radiator) to regulate engine temperature. Liquid-cooled units are built for heavy-duty, whole-home or commercial backup and offer higher output and durability.
Natural Gas
A common fuel source for standby generators connected to a municipal gas line. Natural gas provides continuous fuel without refueling and is a popular choice for home standby installations.
Propane (LP Gas)
A fuel stored in an on-site tank used to power standby generators where natural gas isn't available. A properly sized propane tank ensures extended runtime during long outages.
Electrical Panel (Breaker Box)
The central distribution point that routes electricity from the utility (or generator) to the individual circuits throughout your home. Upgrading the panel is often part of a generator installation or modernization project.
Permit
Official town or municipal approval required before installing a generator, panel, or electrical service. Vaccarella Electrical Services pulls all necessary permits on the homeowner's behalf so the work is legal and inspected.
Inspection
The municipal review of completed electrical work to confirm it meets local and national code. We coordinate every inspection so your generator or panel installation is fully code-compliant and signed off.
Code Compliance
Meeting the National Electrical Code (NEC) and all local building standards. Code-compliant work is safe, insurable, and required for a legal generator or electrical installation.
Generac
One of the leading manufacturers of home standby generators, known for reliable automatic backup power. Vaccarella Electrical Services is an experienced Generac installer for Northern New Jersey homes.
Kohler
A premier manufacturer of home standby generators valued for quiet operation and durable engines. Vaccarella Electrical Services installs and services Kohler generators for homeowners across Northern New Jersey.
Transfer Switch
The component that safely connects a generator to your home's electrical system, preventing backfeed onto the utility grid. Automatic and manual transfer switches are both options depending on the setup.
