Hi all:
I've undertaken the task of building control panels for the water/sewer utility at which I work. These are not UL panels, but do contain power supplies, PLCs, I/O, level controllers, HMIs, etc.
I'm wondering if there is some list of rules as to things like location of components and spacings between DIN rails and gutters, or if it is more of an art where the designer/builder makes these decisions on a case by case basis. I'm somewhat familiar with NFPA 79, UL508A and UL698A but these don't dictate these thing except for access and heat dissipation.
Do people just build a particular way because that's what they were taught? Does AutoCAD make certain assumptions/decisions?
I'd like to know I'm building the best panel that I can, as most of these will be nearly exact duplicates.
Thanks in advance for your wisdom and insight.
