Had an Inspector today wanting 'thumb screws' to hold the tops of the

exhaust fans on. Reason: readily accessible, I kind of smiled and said ok.

There are only four of them, and that was the only gig. I really don't think

I could fight it, what do you think?
 
I wouldn't fight it, but I'd be giggling up my sleeve as I modified the listed fans to meet the fellow's whim.

I'd point to the definition of "readily accessible" as a start, if I were inclined to fight it.
 
If a guy goes up on a roof to service a roof fan, and doesn't at least have a couple nutdrivers with him, he doesn't need to be monkeying around with it in the first place.
 
George,

The definition is : capable of being reached quickly for operation, renewal,

or INSPECTIONS without yada yada yada-- this is where I think he's got it

in his court.

Beside that, I agree with you and Trevor and Marc. I'm going to print the

replys and throw them in his truck tomorrow.
 
Frank,
What about 430.107 ?

I can't believe that the only disconnect for the circuit is inside the fan. Only one disconnect for the circuit is required to be readily accessible. I would expect that to be the branch circuit OCPD.
430.107 Readily Accessible
At least one of the disconnecting means shall be readily accessible.

Don,

True enough, but, then 430.102(B) ex. comes into play, and quite frankly

the thumb screws will be less expensive and easier to install than c.b. locks.
 
By official count there are 8.75 bazillion of these fans installed throughout the USA without 'thumb screws' I think this guy is mistaken.

I don't see how that applies to this case, there is a disconnect within sight of the motor...you can only see the disconnect and the motor after you remove the fan top.

On another note....

440.14 allows the diconnect for Air conditioning and Refrigerating equipment to be "installed on or within" the equipment.

It also requires for it to be "readily accessible".

Is this referring to a breaker mounted (as usually seen) with the handle accessible from outside the unit?

Or does "within" mean that you have to open a cover to access the disconnect?
If so, is this still "readily accessible"?

I've never put a disconnect "within" a cabinet so that opening a cover to access it was required.
The wording of 440.14 seems a little un-clear to me and I'm looking for clarification.

Any thoughts?
thanks

Article 440 does not apply to this installation.
As far as the Article 440 disconnect within the equipment being "readily accessible", it only has to be readily accessible from the equipment...a disconnect inside the same enclosure as the equipment to be disconnected would be readily accessible "from the equipment".

Thanks guys, on this forum you never know what kind of feedback that

you will get. In this case I'm happy to be with the ' he's not right' group.

Just so you know, there will be no thumb screws.
