In my experience, with commercial door operators like these, are are not typically cord and plug connected. That makes the GFCI question moot.

they have no factory cord.we will probably hard wire them with a switch for a disconnect.

Good point. And now that I think of it, I've even seen 3 phase operators on large doors.

From my understanding, the gfi requirement came from homeowners plugging extension cords into the receptacles to run outdoors or other things than run the garage door opener.

Than they step out of the truck pull the manual door release, lift the door and be on their way.

Not in VA, if the barn is on fire the ole boys in the VFDs would probably just drive/plow through the door.

I have never seen that on a large commercial door.

Not a simple release in the middle like on small door but on large doors it is usually a chain connected to the motor operator so you have to actually keep pulling the chain to raise the large doors. I can't think of a door I have wired that did not have a way to raise it manually.

Depends on the design of the operator. Drawbar types, which is about all I ever see have a release mechanism similar to what is seen on residential operators. They only have about 2 feet of release cord so if it is a 12 foot or higher door even NBA players are not going to reach it without assistance of a ladder or something.
Yup, you can do that with a simple residential garage door with no problem as compared to an industrial garage door that is many times larger than that.
When you're intent is on getting the guys to grab their gear and put it out, get on the truck and get out of the barn every second counts. Then to be surprised by a door that doesn't open and then come to your senses to figure out that the door opener isn't going to work then wasting time over-riding the door opener so that the door can be opened manually waists precious time that you need in getting to the fire.

Trucks don't start, garage doors openers fail, if they don't have a plan in place for such things shame on them.

And the very first part of that plan would be to notify dispatch so another company could be assigned to the call. The next step would be the manual operation of the door.

And just driving through the door is probably not the recommended thing to do if they have good contingency plans. Those doors are pretty heavy - who knows what breaks or falls where, better they show up to the scene half a minute later than not at all.
And all of this over a simple GFCI that tripped because of a motor that is above the door and far out of reach of the fireman. But, there must be an exception someone can come up with where the operating motor can be located where the operator can come into contact with the motor that may have become defective in some manor and cause an electric shock to occur. Is the PB station control 120vac or 24vac?
How does one establish the purpose of a GFCI in a firestation garage door application? Is this realy a practical application for a GFCI?
