Faunsdale, AL
They're available is many sizes, what is your load (amps) and how are they going to be installed. "off the pole" sounds like power co territory. We usually are only dealing with after the meter, and then a breaker panel with a main breaker may be your best bet. Whatever you use needs to be rated to interrupt the amps it may see during a fault. The power co should be able to give you that information for your location.
