Can a panelboard be installed on its back in the face up position? The NEC does not seem to address this orientation. Any guidance would be very appreciated.
Hi Thomas, Thanks for the question.
Prior to the 2020 NEC, the Code was not specific with this prohibition. Many jurisdictions would not approve such panelboard installations in the face up orientation. The 2020 NEC now directly prohibits this orientation. See Section 408.43.
