Duct within structural joist

[hhsting]

I know I had precious post about the duct above panelboard however it got closed before i can post pictures


Please see below duct within structure joist. The bottom of structure joist will have ceiling attached (not shown because not their het) so that their is no suspended ceiling.

See the gap in between like doorway that going to have panelboard right under the ceiling.

Would the panelboard install be non compliant to NEC 2017 section 110.26(E)(1)(a) or does the panelboard need to be relocated?

In my opinion, the drywall ceiling will define the top of the space, so the duct will not impose.

I dont understand? Would dedicated space go up to ceiling your saying and panelboard does not need relocation or your saying panelboard has to be relocated duct would be within dedicated space?

The former. Compliant as is.

I'm discussing code, not practicality.

The duct is above the structural ceiling so that's where the dedicated space ends.

Any ceiling that cannot be removed without damage ends the dedicated space.

Agree with above post, no need to move the panel.
You will have difficulty wiring it, but I don’t see an issue why you won’t install a panel there if you wanted to.
