Power outages are an unfortunate reality, and having a reliable generator can be a lifesaver during emergencies or when enjoying outdoor activities. However, using a generator safely and effectively requires careful planning and execution. This comprehensive guide will walk you through everything you need to know, from choosing the right generator to operating it safely and maintaining it for years to come.

Understanding the Basics: Types of Generators

Before we delve into the how-to, let’s familiarize ourselves with the common types of generators:

• Portable Generators: These are the most common type, designed for temporary power needs. They’re typically powered by gasoline or propane and are relatively easy to move. Ideal for home backup, camping, and job sites.
• Inverter Generators: These are a more advanced type of portable generator. They produce cleaner power (consistent voltage and frequency) suitable for sensitive electronics and are typically quieter and more fuel-efficient than traditional portable generators. They’re often smaller and lighter as well.
• Standby Generators: These are permanently installed and connected directly to your home’s electrical system. They automatically turn on when a power outage occurs, providing seamless backup power. These are the most expensive option, but they’re ideal for homes that experience frequent or lengthy outages.
• Industrial Generators: These are large, powerful generators designed for commercial or industrial use. They come in various fuel options, including diesel and natural gas, and are typically used for powering entire buildings or large-scale operations.

This guide will primarily focus on using portable and inverter generators, as they are the most common for home and recreational use.

Step-by-Step Guide: Setting Up and Operating a Portable or Inverter Generator

Regardless of the specific model, the following steps are essential for safe and efficient generator operation:

Step 1: Choosing the Right Generator for Your Needs

The first step is determining your power requirements. Calculate the wattage of all the appliances and devices you plan to power simultaneously. The wattage of devices can usually be found on their labels. Add these up to determine the total wattage. Always choose a generator that exceeds your total running wattage by at least 20% to account for startup surges, particularly from appliances that utilize motors (like refrigerators, air conditioners, etc.). You need to consider both running wattage (the power they consume continuously) and starting wattage (the extra power needed when they initially start). Generators have these two wattage ratings; make sure your intended devices’ starting and running wattage is considered when choosing the right generator for your needs.

Consider the following factors when selecting a generator:

• Wattage: Ensure it meets your power requirements.
• Fuel Type: Decide between gasoline, propane, or dual-fuel models. Gasoline is the most common but might not store as long. Propane is more readily stored for long periods but requires tanks and a regulator. Dual fuel gives you both options.
• Runtime: Check how long the generator can run on a full tank of fuel.
• Noise Level: Consider the noise output, especially if you’re in a residential area. Inverter generators are quieter.
• Portability: If you need to move it frequently, choose a lightweight model with wheels.
• Features: Look for features like automatic shut-off, low oil indicators, and multiple outlets.

Step 2: Preparing for Generator Use

Before using your generator, make sure you have all the necessary supplies and safety equipment:

• Fuel: Enough fresh fuel (gasoline or propane) for the duration you expect to use it. Store fuel in approved, sealed containers and keep them away from living areas and heat sources. Always fill the generator in an open, well-ventilated space while the engine is cool. Never attempt to fill a generator while it is hot or running.
• Extension Cords: Heavy-duty, outdoor-rated extension cords with the correct amperage rating for your appliances. Never use indoor cords outdoors. Use the shortest cord practical for each application to reduce voltage drop.
• Surge Protector: To protect sensitive electronics from voltage spikes.
• Carbon Monoxide Detector: Absolutely essential! A carbon monoxide detector should be placed near the area where you are running the generator, as well as inside your home to help alert you to any leaks into your living space. Do not ever run a generator indoors or in a garage attached to a home.
• Fire Extinguisher: A Class ABC fire extinguisher.
• Safety Gloves and Eye Protection: For refueling and maintenance.
• Owner’s Manual: Keep the manual readily accessible for reference.

Step 3: Finding a Safe Location

Generator placement is crucial for safety. Always operate your generator in a well-ventilated area, away from windows, doors, and vents. Carbon monoxide is odorless and deadly, and it accumulates quickly in enclosed spaces. Here’s a detailed guide:

• Outdoors Only: Never run a generator indoors, in a garage, a basement, a crawlspace, or any partially enclosed space. Even with a door or window open, carbon monoxide can build up to lethal levels.
• At Least 20 Feet Away From Your House: Position the generator at least 20 feet away from any windows, doors, or vents to prevent carbon monoxide from entering the building.
• Flat and Stable Surface: Place the generator on a flat, stable surface to prevent it from tipping over or vibrating excessively. Make sure it is on solid ground and not on grass or other surfaces that might block airflow. A concrete slab or well-packed dirt is best.
• Away From Rain and Moisture: Although many generators are designed for some outdoor use, avoid placing the generator directly in the rain or where puddles may form. Provide some form of shelter or cover (a simple tarp supported with adequate airflow underneath) if needed to keep it out of the worst weather. Never operate a generator in standing water or touch it when wet.
• Away From Flammable Materials: Keep the generator away from flammable materials, such as dry grass, brush, or combustible debris.
• Away From Traffic: Make sure the generator is placed where it won’t pose a safety hazard for foot or vehicle traffic.

Step 4: Connecting Appliances and Devices

Once the generator is in place, you can begin connecting your appliances and devices. This is critical to safe operation. Follow these steps carefully:

• Avoid Overloading the Generator: Start by connecting only the most essential appliances and devices first to avoid overloading the generator. Calculate the combined wattage before plugging anything in. Never plug in devices that exceed the generator’s rated wattage. Overloading can damage the generator and the devices connected to it.
• Use Appropriate Extension Cords: Use heavy-duty, outdoor-rated extension cords with the correct amperage rating for your appliances. Make sure the cords are in good condition, with no frays or damage. Never use indoor-rated cords outdoors. Use the shortest cords that will get you from point A to point B.
• Use a Surge Protector: Use a surge protector, especially when connecting sensitive electronics like computers, TVs, and gaming consoles, to protect them from voltage fluctuations.
• Plug In Appliances Directly: Ideally, plug appliances directly into the generator’s outlets rather than using long extension cords when possible to minimize voltage drop.
• Never Backfeed: Never backfeed power into your home’s electrical system by plugging the generator directly into a wall outlet. Backfeeding is extremely dangerous and illegal. It can energize power lines, potentially endangering utility workers and neighbors. This should only be done if you have a properly installed transfer switch.
• Start Appliances One at a Time: Start high-demand appliances (like refrigerators, freezers, and air conditioners) one at a time to prevent overloading the generator on startup.
• Review the Owner’s Manual: Consult your generator’s owner’s manual for specific information regarding appliance connections.

Step 5: Starting and Running the Generator

Now that everything is connected, it’s time to start the generator:

• Check Fuel Levels: Before starting, double-check that the fuel tank is filled appropriately, making sure to not overfill the tank.
• Turn the Fuel Valve On: Locate the fuel valve or switch (typically located near the fuel tank) and turn it to the ‘on’ or ‘open’ position.
• Turn on the Choke: If your generator has a choke lever, move it to the ‘start’ or ‘choke’ position, which helps start the engine when cold.
• Start the Generator: Most portable generators use either a pull-cord recoil start or an electric start. Follow the steps provided in your generator’s owner’s manual for your specific start type.
• Recoil Start: If using a recoil starter, grasp the starter grip firmly and pull briskly. It may take several pulls to start the engine. Do not yank with excessive force.
• Electric Start: If using electric start, turn the key or push the button to start.
• Adjust the Choke: After the engine starts, gradually move the choke lever back to the ‘run’ position. If the generator engine is warm, the choke will not be needed.
• Let it Warm Up: Allow the generator to run for a few minutes to warm up before placing any significant electrical load on it.
• Monitor Performance: Keep an eye on the generator while running, looking for any unusual sounds or smells. Also, periodically check that it is still a safe distance from buildings and there is proper ventilation.
• Refuel with Care: When refueling, always shut off the generator and let it cool down before adding more fuel.

Step 6: Shutting Down the Generator

When you’re finished using the generator, it’s essential to shut it down properly:

• Disconnect Loads: Disconnect all appliances and devices before shutting down the generator. This will prevent sudden surges that might damage the equipment when it starts again.
• Turn the Engine Switch Off: Turn the engine switch to the ‘off’ position or the designated ‘stop’ position.
• Turn the Fuel Valve Off: Turn the fuel valve to the ‘off’ or ‘closed’ position to prevent fuel leakage and allow the fuel in the carburetor to be used up if storing the generator long term.
• Let it Cool Down: Allow the generator to cool completely before storing or transporting it.
• Store it Properly: Store the generator in a clean, dry location, away from moisture and extreme temperatures.
