Frequently Asked Questions (FAQs)

1. What size generator do you need to run an average size house?

How Big of a Generator Do I Need to Run a House? With a generator rated at 5,000 to 7,500 watts, you can run even the most critical household equipment, including things such as refrigerator, freezer, well pump, and lighting circuits. A 7500-running watt generator can run all these appliances at once.

2. What size generator do you need to run a small house?

The typical house will need about 25 to 40 kilowatts, so a 20kw generator is too small. An average American home needs around 30 to 50 kilowatts of power for its basic electrical needs. In order to ensure that your home has enough electricity when the grid goes down, you'll want at least a 30 kW generator.

3. Can a generator stay outside in the rain?

Never run it in a garage, even if the doors are open. Instructions for a portable generator warn you not to run it in the rain. To protect it from moisture, the Consumer Product Safety Commission recommends operating it on a dry surface under an open, canopy-like structure.

4. Can a generator be placed outside?

Because outdoors is the only safe place to operate a portable generator, taking it outside is absolutely mandatory to keep your family safe from carbon monoxide.
