Yes it is a violation unless it is shown to be impracticable to mount it vertically.
OK it looks like you got me again, how about a code reference 'cause I can't find one.

Impracticable.
That pretty much rules out sideways.
240.33 Vertical Position. Enclosures for overcurrent devices
shall be mounted in a vertical position unless that is
shown to be impracticable. Circuit breaker enclosures shall be
permitted to be installed horizontally where the circuit breaker
is installed in accordance with 240.81. Listed busway plug-in
units shall be permitted to be mounted in or
edit: BTW I am not trying to GET you... I just thought it should be pointed out that the NEC DOES prefer vertical mount... it is not just either or.
IMO there would have to be a VERY good reason to do it... not just convenience.
I think this is not refering to sideways as shown in the picture although the handles still need to be up when in the on position which is covered by different section. What this section is referring to is a panel mounted on non vertical surfaces like a floor or ceiling or facing up on top of equipment.

Although it is understandable that this absurd view point may be supported by someone who did not even know about 240.33 and is trying to save face................![]()

7. Can a load center be mounted in a horizontal position?
Article 8, page 71 of the 1925 NEC
The term “horizontal” can be interpreted two ways:
1) Rotated on the wall 90 degrees
2) Mounted on the ceiling or on or under the floor
Code Reference: 240.33 and 240.81
The issue over horizontal mounting goes back to the 1925 NEC. The specific issue was to prohibit fused switches from being mounted on the ceiling (under a floor) where the constant vibration from the floor traffic could cause the fuse to dislodge from a fuse clip and drop against the enclosure creating a ground fault.
The language in 240.33 was changed in the 2002 NEC with a substantiation that revolved around rotating the enclosure 90 degrees not from wall to ceiling or floor.
240.33 Vertical Position.
Enclosures for overcurrent devices shall be mounted in a vertical position unless that is shown to be impracticable. Circuit breaker enclosures shall be permitted to be installed horizontally where the circuit breaker is installed in accordance with 240.81. Listed busway plug-in units shall be permitted to be mounted in orientations corresponding to the busway mounting position.
240.81 Indicating.
Circuit breakers shall clearly indicate whether they are in the open “off” or closed “on” position.
Where circuit breaker handles are operated vertically rather than rotationally or horizontally, the “up” position of the handle shall be the “on” position.
Actually I said it was absurd. And let's be honest, it is certainly no more egregious than comments others (including you) have said. Please don't take exception. Everyone on here pokes fun with sometimes lewd comments. I truly had no idea you would be so sensitive to it.Well thanks, I took exception to calling kwireds and my thoughts ridiculous.
Sorry ! I should have been more specific. I meant horizontal in a wall as in the picture the op posted.Is a horizontal installed panel a NEC violation?:-?
I often see panels without doors mounted face-up in laundromat islands, between the back-to-back machines.
