Home generators come in several varieties. Portable generators produce temporary power and sit outside your home, running on gasoline or propane. Standby generators, sometimes called permanent generators, stay installed and can automatically turn on during power outages. They typically run on natural gas or propane lines already connected to your home. A third option, whole-home inverter systems, use battery storage combined with solar panels or other power sources.

Understanding these differences matters because each type has different installation requirements. Portable generators need a safe outdoor location away from windows and doors. Standby units require professional installation, permanent connections to your fuel source, and wiring that integrates with your home's electrical panel. Battery-based systems need dedicated space and may require roof modifications if solar panels are part of the setup.

The guide explains how generators connect to your home's electrical system through a component called a transfer switch. This device automatically detects when your main power fails and switches your home to generator power. Without a transfer switch, dangerous electrical backfeeding can occur, where generator power flows back into utility lines and injures utility workers.

Practical takeaway: Before exploring generator options, learn the basic differences between portable, standby, and battery-based systems so you understand which type might work for your home and situation.

Local Codes, Permits, and Inspection Requirements

Every location has building codes that govern how home generators must be installed. These codes exist for safety reasons—to protect your family, your home, and utility workers. Your local building department, city hall, or county office maintains these codes. Before installing any generator, you need to understand what your area requires.

Most locations require a building permit before generator installation. This isn't bureaucratic busy-work; it ensures a licensed inspector will examine your installation and verify it meets safety standards. The permit process typically involves submitting plans showing where your generator will sit, how it connects to your electrical panel, what fuel source it uses, and how it will be ventilated. Review times usually take one to four weeks, depending on your area's workload.

Inspection requirements vary by location. In many areas, you need electrical inspections once the generator is wired into your home, and sometimes a second inspection after everything is complete and operational. Some places also require inspections of gas line connections if your generator uses natural gas or propane. Inspectors verify that transfer switches are properly installed, that wiring meets code, that your generator sits at correct distances from windows and doors, and that fuel lines are safely routed and properly tested.

Location-specific considerations include setback requirements—rules about how far your generator must sit from property lines, windows, and doors. These rules protect neighbors from noise and exhaust. Many areas require generators to be at least 5 feet from bedroom windows and 1 foot from property lines, but your local code may differ. Noise regulations also vary; some areas allow 75 decibels during certain hours, while others have stricter limits. The guide explains how to research your specific local requirements by contacting your building department directly.

Gas and propane connections have separate codes managed by your local gas utility or plumbing department. Fuel lines must be correctly sized for your generator's consumption, properly supported, and tested for leaks. Most areas require a licensed plumber or gas fitter to handle these connections.

Practical takeaway: Contact your local building department before purchasing any generator to learn what permits, inspections, and setback distances your area requires. This conversation will save you money and installation problems later.

Electrical System Integration and Transfer Switches

Your home's electrical panel is the central hub where all power enters and distributes throughout your house. When a generator connects to your home, it must integrate safely with this system. This is where transfer switches become essential. The guide explains how transfer switches work and why they're legally required in every location.

A transfer switch is an electrical device that sits between your main power source and your electrical panel. It continuously monitors your utility power. When utility power fails, the switch detects this loss, waits a brief moment to ensure the power won't immediately return, and then switches your home to generator power. When utility power returns, the switch waits for a set time and then switches back. This happens automatically with standby generators; with portable generators, you manually flip the switch.

Two types of transfer switches exist: automatic and manual. Automatic transfer switches work with standby generators and require no human action. Manual transfer switches work with portable generators and require you to physically move a lever to switch power sources. A critical safety feature of both types is that they prevent generator power and utility power from both feeding into your home simultaneously. This dual-power situation creates extreme danger; it can electrocute utility workers repairing downed lines in your neighborhood.

The guide explains load management—how to decide which circuits in your home connect to the generator. You cannot always run your entire house on a generator, especially portable ones, because they have limited power capacity. A typical portable generator produces 5,000 to 7,500 watts. Your whole home might require 20,000 to 30,000 watts during peak usage. This means you select which circuits matter most during outages: kitchen, bathrooms, heating/cooling, refrigerator, and lights. Your electrician helps determine which circuits to connect through the transfer switch.

Standby generators produce more power—typically 10,000 to 20,000 watts—and can handle more circuits. Some larger standby units can power an entire home, though this is less common in residential settings.

Practical takeaway: Understand that a transfer switch is not optional—it's a legal safety requirement. Plan which home circuits are most important to you during a power outage, as this determines how large your generator needs to be.

Fuel Source Options and Storage Considerations

The fuel your generator uses affects installation requirements, operating costs, and convenience. The guide explains the three main fuel options for residential generators: gasoline, propane, and natural gas. Each has different storage needs, safety considerations, and ongoing requirements.

Gasoline generators are the most affordable upfront and widely available. Gasoline is sold at nearly every gas station. However, gasoline degrades over time, especially in storage. After three to six months, untreated gasoline begins breaking down, forming gum and varnish that clog your generator's fuel system. If you store gasoline for emergencies, you must add fuel stabilizer and rotate your supply regularly. Gasoline also presents fire risks; you must store it in approved containers, away from your home, in a cool location away from ignition sources. Most areas limit how much gasoline you can store at home—typically 25 gallons in approved cans.

Propane generators solve the fuel degradation problem. Propane doesn't break down in storage, so it remains ready for years. You can store a propane tank beside your home (following setback distances). Propane is less toxic than gasoline and produces cleaner emissions. The drawback is that propane costs more than gasoline and requires a supplier relationship for refills. You can't simply buy propane at a gas station; you must schedule deliveries or drive to a propane distributor.

Natural gas generators connect directly to your home's existing natural gas line, eliminating fuel storage entirely. If your home already uses natural gas for heating or cooking, adding a generator is straightforward—the gas company runs a line to your generator. The fuel is always available and never degrades. However, not all neighborhoods have natural gas service, and natural gas is generally more expensive than propane per unit of energy. During large regional outages, natural gas pressure sometimes drops, reducing your generator's output.

The guide provides information about generator fuel consumption rates. A typical portable gasoline generator burns through a tank (5-7 gallons) in 8-12 hours of operation, depending on load. A standby propane generator might consume 2-3 gallons per hour under full load. Knowing these rates helps you plan fuel storage and budget for long outages.

Practical takeaway: Choose your fuel source based on what's available in your area and your ability to manage fuel storage or supplier relationships. Natural gas
