I have an overhead door with the disconnect locate 20 ft off the ground. I have scanned both the NEC and NFPA 79 for direction but everything seems interpretable. I requested it to be lowered to within the 6'7" zone. I was told all that I needed was to tie on a rope with a red handle suspended in the zone. I question the practicality of locking it out that way or above. The circuit breaker is located across the plant. I included the photos. What do you all think?

There is no code reason to move the switch and it does not need s rope.

404.8(A)Exception No. 2: Switches and circuit breakers installed
adjacent to motors, appliances, or other equipment that
they supply shall be permitted to be located higher than 2.0
m (6 ft 7 in.) and to be accessible by portable means.

That disconnecting means is for servicing the motor, it is not an emergency power off switch.

That is a code section everyone should have taped to the inside lid of their toolbox.
 
As then others have noted it is Code compliant as installed. Its a matter of the switch being readily accessible for someone working on the door or being readily accessible as a 'emergency stop' as indicated by Iwire.
Nothing prevents you from installing the rope if desired or installing two switches if desired,

Thats just it, there is no emergency cut-off.

The NEC does not require an emergency switch.

If another code does requires an emergency switch for this application the disconnecting means is not it and lowering it to the ground would not change that.

I agree either of those or a mushroom-head E-stop down low but any of those would be beyond what the NEC requires. :)

I do not know enough about other safety codes to comment about them other to say that picture looks like a typical installation we have done 100s of times so I do not believe an E-Stop is required.

Off topic but do those type doors have all the sensors and safetys that home garage doors have?
