Is there enough space when the door to the room is open?

I would think it would be a supplemental disconnect and would fall under 240.10.

Do we have a room and an enclosure?

110.26 does not apply. You are not working the disconnect 'hot'. Treat it like you would for a disconnect for a furnace.

240.10 Supplementary Overcurrent Protection.

Is this a fusible disconnect? Is there ready access to the overcurrent device to shut down power?
