There was a change in the 2020 NEC 240.33 that no longer allows OCPD enclosures to be mounted horizontally under some circumstances.
It was changed from: Enclosures for overcurrent devices shall be mounted in a vertical position unless that is shown to be impracticable.
To: Enclosures for overcurrent devices shall be mounted in a vertical position.
It seems to me that this would apply to AC and DC fused combiners and to string inverters with fused inputs. What's everyone's take on this?
