Disconnecting means .

The rule for the disconnect being within sight and within 50 feet, very seldom , if ever, works out when your talking about a breaker serving as a disconnect means in relationship to equipment being served.

Why is that . I am understanding what your saying but according to the code section it's within code . and 440 . 14 says if you have a disconnecting means on or within it meets code

Yes that part of it does.

I'm talking about if the unit did not have it's own disconnecting means.

Take your scenario for instance.

Even though the electrical panel may be within 50 feet, by the letter of the law, it is not within sight of the unit, and therefore, the breaker in the panel could not be used as the disconnecting means.

And, as I was saying earlier, it hardly ever is, unless the equipment just so happens to be located in the same room as the electrical panel.

Even when 3r Panels are located on a roof to service roof top units. The panel may be just within a few feet of a unit, but, the "Within Sight Of" thing never actually seems to work out at all.

Will those SQ D QOU breakers at the top of the unit suffice as a disco?

Yes, because they're readily accessible by virtue of being accessible without having to open or remove anything.

My Q is, does a locking panel door meet 110.25?

Please review 110.25. The answer is no.

is this a point of controversy?
:?
110.25 Lockable Disconnecting Means. If a disconnecting
means is required to be lockable open elsewhere in this Code, it
shall be capable of being locked in the open position. The
provisions for locking shall remain in place with or without the
lock installed.
Exception: Locking provisions for a cord-and-plug connection shall not
be required to remain in place without the lock installed.

there are multiple ref's in art 430 Part IX. Disconnecting Means, as well as art 450, etc

yet we have....

Doesn't that semi-transparent cover (top center of the unit) have circuit breakers behind it? That is a local disconnecting means.

Sorry I stepped on others toes, should have read all the replies first.

The requirement is that the disconnecting mean be "located within sight from" so from the unit can you see the panel?

Art 440 doesn't apply unless this unit contains a hermetic compressor. 422 does apply and has similar rule though, but if it is 1/8 HP or 300 VA or less may not need a local disconnect.

A picky inspector could argue that the corner next to the panel impedes sight of the panel, but I'd allow it.

And the picky inspector would be correct.

Remember, the rule is not referring to what you can see if you take a few steps back.

It refers to the equipment.

If your the furnace unit in the closet you can't see the panel, and, if your the panel, you can't see the furnace unit around the corner in the closet.

some may want to say the furnace in the closet is not within sight simply because the closet is "another room". Don't know that I fully agree with that in all cases though.
