My recent home inspection had an ac unit disconnect under a crawl space with a lock on it …( the lock was removed for inspection) is this a proper placement??

The disconnect is required to be accessible and in line-of-sight from the appliance. Being located in the crawlspace, it doesn’t sound like it would meet either of those requirements.

Why wouldn’t a disconnect switch in a crawl space be accessible?

Why is’t a GFCI outlet on a ceiling for a garage door opener not accessible?

Because there two separate requirements defined in Article 100, Accessible and Accessible , *Readily *. The GFCI is required to be readily accessible. Accessible by definition has a lesser requirement so the GFCI in the ceiling would be accessible but not readily accessible.

Great info.
Article 440 requires you to locate the disconnecting means within sight of, and readily accessible from, the air-conditioning or refrigerating equipment (Figure 440-2). “Within sight” means visible from, and not more than 50 ft from, each other [Article 100] (Figure 440-4). You can install the disconnecting means on or within the air-conditioning or refrigerating equipment-but not on the access panels (Figure 440-3).
This requirement has two exceptions:
You can lock the switch open if the equipment is essential to an industrial process and the installation meets certain requirements.
So do I read this wrong or has it changed.

That’s not the issue. As Jeff stated, "in line-of-sight from the appliance, is the issue.

I guess it would depend on the crawlspace, but in SoCal, most crawlspaces would not qualify as “accessible” locations…
and CERTAINLY wouldn’t qualify as “readily accessible”
The NEC’s definition of readily accessible states: “capable of being reached quickly for operation , renewal, or inspections without requiring those to whom ready access is requisite to actions such as to use tools, to climb over or remove obstacles, or to resort to portable ladders and so forth.”
