If you absolutely need to use a gas generator in your home, take the following safety precautions:
1. Ensure adequate ventilation. Open windows and doors to create cross-ventilation and allow fresh air to circulate.
2. Place the generator outside. If possible, place the generator at least 20 feet away from your home and any windows or doors.
3. Never use a generator in an enclosed space. This includes garages, basements, and crawl spaces.
4. Install a carbon monoxide detector. Place a carbon monoxide detector in your home near the bedrooms and living areas. Test the detector regularly to ensure it's working properly.
As for the size of the generator you need, it depends on the total wattage of the appliances and devices you plan to power. Add up the wattage of all the devices you'll be using and select a generator that can handle that load. It's also a good idea to get a generator that has a little extra capacity, in case you need to add additional devices later.
Here are some general guidelines for generator sizing:
* Small appliances and devices (up to 1,000 watts): 2,000-watt generator
* Medium-sized appliances and devices (up to 3,000 watts): 3,500-watt generator
* Large appliances and devices (up to 5,000 watts): 5,500-watt generator
It's important to note that these are just guidelines, and the actual size of the generator you need may vary depending on your specific needs. If you're not sure what size generator you need, consult with a qualified electrician.
