Safety Considerations
Portable generators can be dangerous if used improperly. Always follow safety guidelines to protect yourself and others.
- Proper Usage
Never run a generator indoors or in enclosed spaces. Place it outdoors at least 20 feet away from windows and doors. Use heavy-duty extension cords rated for outdoor use.
Don’t overload the generator. Check its wattage rating and stay within limits. Plug appliances directly into the generator or use a properly rated transfer switch.
Turn off the generator and let it cool before refueling. Use fresh gasoline and store fuel in approved containers away from living areas.
- Maintenance Tips
Generators need regular maintenance. Check oil levels before each use and change oil regularly. Clean or replace air filters as needed. Inspect fuel lines for cracks or leaks.
Keep the generator dry and protected from rain and snow. Use a canopy or shelter designed for generators if needed.
Test your generator monthly and run it for 30 minutes. This keeps parts lubricated and battery charged. Have a pro service it yearly.
- Carbon Monoxide Concerns
Carbon monoxide (CO) from generators can kill in minutes. It’s invisible and odorless.
Install CO alarms on every level of your home and test them often.
Know the symptoms of CO poisoning: headache, dizziness, weakness, nausea, vomiting, chest pain, and confusion.
Never use a generator in a garage, even with the door open. CO can build up quickly in enclosed spaces.
Frequently Asked Questions
How long can a portable generator run?
Run times vary, but many can operate for 8-12 hours on a full tank of fuel. Larger fuel tanks allow for longer run times.
Can I use a portable generator with my home’s electrical panel?
You should never connect a portable generator directly to your home’s wiring. Use a transfer switch installed by a licensed electrician instead.
How do I decide the generator size I need to run my house?
To size your generator, add up the wattage of appliances you want to power. Start with essentials like fridge, lights, and heating.
A 5000-7500 watt generator can run most critical home systems. For full house power, you might need 10000-12000 watts. Make a list of your must-have items to get a clearer picture.
