  1. Max "Generator" Stanford says:

    What kind of power do fans usually draw? It doesn’t seem like it would be that much. I was thinking about someone living in a rural area where the electrical system can be a bit touchy. If there was a natural problem or failure how much could a generator pick up comfortably? Would it be worth it to disconnect non-essentials like a fan?

  2. Dave Rongey says:

    Hi Max,
    The electrical load of the fan would depend on the size of the fan as there are so many different types of fans and exhaust fans. This article is about bathroom exhaust fans which are relatively small, the motors is fractional HP, and require a low amount of power so they would not significantly affect the load of a generator.
    Hope this helps.
