Essential Operation Guidelines
Using your whole-house generator safely means following specific steps when you start and stop it. Control how much power you use and avoid putting too much strain on the system.
Safe Startup and Shutdown Protocols
Before starting your generator, turn off the main power to your home. This step helps prevent backfeeding, which can cause serious electrical hazards.
Start the generator outside, away from windows and vents, to avoid carbon monoxide poisoning. Let it run for a few minutes to stabilize before turning on any appliances.
When shutting down, turn off all connected devices first. Then, switch off the generator and wait for it to cool down before refueling or servicing.
Always follow manufacturer instructions for the safest process.
Managing Electrical Loads
Not all appliances can run at once on your generator. Prioritize essential devices like refrigerators, lights, and medical equipment.
Use a transfer switch to control which circuits get power. This switch safely connects the generator to your home’s wiring and prevents backfeeding.
Keep a list of appliances and their wattage. This helps you plan which devices you can run at the same time without overloading your generator.
Avoiding Overloading
Overloading your generator can cause damage and safety risks. Watch the generator’s load meter or display to see how much power you use.
If you notice flickering lights or a sudden shutdown, your generator might be overloaded. Turn off some devices to reduce the load.
Never add appliances that exceed your generator’s rated power. If you need more power, upgrade to a larger unit or run fewer devices at once.
Carbon Monoxide Safety Measures
Protecting your home and family from carbon monoxide (CO) is crucial when you use a whole house generator. You need to understand the dangers CO poses, place your generator in the right spot, and have the right detectors installed.
Risks of Carbon Monoxide Poisoning
Carbon monoxide is a colorless, odorless gas that can build up quickly if your generator isn’t vented properly. It can cause headaches, dizziness, nausea, and in serious cases, loss of consciousness or death.
Because you can't see or smell it, CO poisoning can happen without warning. Generators produce CO while running, so placing your generator indoors or too close to the house increases the risk.
Never use your generator in enclosed spaces like garages or basements where CO could collect.
Ventilation Requirements
Place your generator outside, away from windows, doors, and air intakes. This placement keeps fresh air flowing and prevents CO from entering your home.
Local building codes often require specific distances. For example, you might need to keep your generator at least 5 feet from any openings in your house.
Choose a flat, stable surface with good airflow around the generator. Avoid vents or exhaust settling near areas where people spend time, like patios or playgrounds.
Installing CO Detectors
CO detectors warn you about dangerous gas levels. Place detectors on every floor of your home and near all sleeping areas.
Choose detectors that meet safety standards and have battery backups. Test your detectors monthly and replace batteries at least once a year.
Some models connect to your home’s security system and send alerts to your phone. This feature gives you extra peace of mind, especially when you are away.
