How much is a gas generator?

The cost of a gas generator will vary depending upon the brand, type, size and capacity. Pricing can range from the low hundreds to the upper thousands. For more pricing information, feel free to reach out to a local United Rentals representative.

How big of a gas generator do I need?

Deciding on the right size gas generator for your needs depends on the amount of power you will need and how long you'll be using it. A smaller-sized gas generator can operate a few select appliances in an emergency situation or when there is a brief outage; larger units are capable of powering entire homes during longer outages due to storms or natural disasters. For more support in selecting a gas generator, take a look at this article on Portable Generator Sizes in Project Uptime.

Do gas generators need to be grounded?

Yes, gas generators must be grounded. This can be done with a grounding rod that is inserted into the earth and attached to the generator or by using an appropriate adapter plug.
