    No....I've seen quite a few with breakers at the outside compressor. Newer builds generally have the disconnects - but for a while, they were doing breakers there, too.

    In that case you would still have a breaker in the panel. The wire needs to be protected from the source.

    Yup - which is why it made more sense when they went from localized breakers to disconnects.

    Looks like this guy fixed his fuse problem. Line 1 is kinda toasty too. I think his original problem will be rearing its ugly head soon.

    All of the a/c units I have worked on have an actual breaker in the external box, not just a disconnect. But again, perhaps some installations are different.

    I do see quite a few fused AC disconnects, the rationale being the circuit breaker in the main panel protects the wiring, while fuses can be selected to give better protection response for the load (motor/condenser).

    I've seen breakers, fuses, and disconnects---but always a breaker in the main house to cut power to the A/C system. I've also seen electricians do the unexpected regularly, from leaving twisted wires sticking up in the attic to wiring an electric stove off a 20a breaker, and a hot water tank off twin 50s. The rule is test everything and don't trust anything without testing it. 220 will get your undivided attention...and 110 kills more people.

    Unless your a/c man's tried and trusted, I'd back up what he says by calling your electrician to check the supply. Your home/family's worth the trouble.
