Does 110.26(F) Apply To ATS?

[George Stolz]

I've got an existing gasfired heater barely hanging over a new ATS. Does 110.26(F) apply to an ATS?

Does 110.26(F) apply to an ATS?

What does the S in ATS stand for? (JMO)

All switchboards

I'll take that back, an ATS doesn't meet the 100 def for switchboard.

How about PV inverters? Also not a panelboard, switchboard, or motor control circuit?

There is a reason that that article only names four specific components. Once the ATS (or inverter) is installed, it is not likely you will need to come back later and add more conduits. So the room above the component does not need to be reserved for future conduits. IMHO, 110.26(F) does not apply to either component.

George, is this combo package unit with a switch and panel board with breakers?

 

[George Stolz]

No, just an ATS.

Whats the deal George, I "had" to install one above a back flow preventer today. Got inspection tomorrow. Charlie, if the inspector takes issue, may I quote you?

What if the ATS is service rated with a breaker in it?

 

[bluesmoke...oops]

What if the ATS is service rated with a breaker in it?

I would then say yes it does because of 110.26(A)

Working space is not the same as dedicated equipment space.

Is the bottom of the heater at a height at least 6 1/2 ft above the work platform (I'll assume it is higher than the ATS since OP said it is barely hanging over the ATS)?

 

[George Stolz]

Yes, it's at 6' 8" to the bottom of the heater. We detoured an existing conduit that was going to be behind the ATS, giving us the pinch we needed. There's still the exhaust pipe, but it's way up there.

Thanks all for the piece of mind!

Sure. Would you like me to email you my fee schedule?
