Hi,

I have designed 2-section panels suppose to be installed in electrical closet.
Because of the constraint space, we don't have enough room to install panel sections side by side. Electrical contractor suggest to stack the panels, one on top of other, the total two panel height is around 91" and there is about 20" space above panel top to ceiling Will this still comply with NEC? Thanks!

Take a look at 240.24(A).

That would be my concern too.

I have one now that has the same problem. I had them move all of the breakers to the bottom of the panel so that they comply. Of course there is no way for me to prevent them from putting some in later, but since everyone here will tell you, you can't inspect for the future, I have passed it.

I agree, I don't inspect for what may happen in the future, if the installation meets the code, it passes.

You can stack a pair of typical 42 circuit panels but the bottom one pretty much has to sit on the floor.

One of the customers we serve orders switchgear with two 42" circuit panels in each section, the bottom breakers are about 8" to 10" off the floor.

The NEC does not have a minimum breaker height, only a maximum height of 6'-7".

Agreed, no minimum height and the highest operating handle of any overcurrent device can't be higher than 6'7".
