a/c disconect min height

[Dave_B]

I cant find a minimum height requirement for mounting an air conditioning disconnect on a building in 440.14 or in 430. But I thought there was something some where about minimum height for out door equipment. I have an existing disconnect 6" above grade and really don't want to move it.

 

[480sparky]

There is none.

I didn't rough this in, and I was royally POd when I was tasked to trim it out, but it passes.

Thanks 480Sparky don't know why I thought there was a minimum though I think there should be.

 

[480sparky]

.......... though I think there should be.

I do to, considering I had to lay down on the frozen solid-as-a-rock ground to wire that thing up.

Not trying to hijack the thread but what about a max. height? 440.14 says it should be readily accessible, which by the definitions says you cannot use portable means. But 240.24 A 4 states that if it is by the utilization equipment it may be accessed by portable means.

Guys,

Obviously, this is ADA compliant!

And I live in a shoebox with my 47 brothers and sisters in a culvert that floods every time it rains, and we have one bean to eat between us every day, and the front door and the back door share a hinge..........

The problem with a minimum height is that at some point the layout will require something lower than what the code requires.

Not trying to hijack the thread but what about a max. height?

6'-7" to the operating handle in the highest position.

6'-7" to the operating handle in the highest position.

240.24 A 4 states that if it is by the utilization equipment it may be accessed by portable means.

Can you clarifie ?

 

[iwire]

Take your pick, 240.24(A) or 404.8(A), one or both will apply.

..... and I would not call a disconnect located above a dropped ceiling 'adjacent to' an air handler in a nearby closet.

I'm not going in the closet:grin: My question was more directed to a air handler suspended from the ceiling on rod and strut with the disconnect being next to the elect. access panel on the air handler. Both would need portable means to reach.

Yeah I mixed this up with another ongoing thread about a closet and an AHU.

That would be fine and something I do all the time ........... of course I see no exception to do so in 110.26.

Some of the AC disconnects that have receptacles in them do have a 2' minimum height in their install instructions. The brand I'm thinking of is the "Midwest" brand non fused, 60A single phase disconnect.
