Hi Guys, referring to section 110.26 and working space. When the voltage is only 120v/208 what is the clearance required. Is it only the 36" or does the door swing plus 24" need to be accounted for. to allow for egrees to/ from working space.
Thanks
 
Junction boxes do not require working space. For a control panel the 36" distance would be from the door front when closed. The door would need to open a minimum of 90°.

Under the 2023 code that does need to be accounted for, no matter what size the equipment is. In the 2020 code this only applied for large equipment as covered in 110.26(C)(2). In the 2023 code the language about open doors not impede the egress path was moved to the parent text of 110.26 so it applies anywhere that an open door could restrict the egress path to less than 24" wide.

Don does this apply to the door of the control panel or a door in the egress path?

The door of the control panel cannot impact the depth of the egress path.
How many panels have you worked on where you had to close the door before you could move away?
