We are looking at a new machine installation. The machine has a larger footprint than the machine it is replacing, creating a space issue. We are looking at installing a floor exit conveyor for the machine that sits 12" above the floor surface adjacent to the machine. The conveyor is 5-6 feet wide and will bump up again the drive side of the machine - in front of two electrical panels. The panels are raised up, so there is no issue with the panel doors opening 90 degrees and the conveyor is wide and deep enough to meet the clearance requirements under 110.26 Spaces About Electrical Equipment. My question is this: can the conveyor itself (if locked out), be considered "working space"? Also - since the conveyor is an exit conveyor with product passing it for a few seconds every few minutes be considered "dedicated equipment space"? The panel will be temporarily blocked when product passes by, but otherwise clear.
When service or troubleshooting is conducted, the exit conveyor will be cleared and the conveyor locked out, so it will be like standing on an elevated work platform with a non-moving plastic surface. There will be no gap between the panel and the conveyor, so the electrician will have room to work without a tripping or egress issue.
Any help appreciated. I am using the NEC 2008 handbook, but the additional notes did not add any clarification for a situation like this.
