I don't know about an industry standard, but I start at the service discount (SD 1). Then if you have a breaker stack, it would be B1, B2. They would say "Fed From SD 1". Then if it hit a panelboard, PB 1 Fed From B1, sometimes you may only have one panelboard. Then the lighting panels get the "LP1 Fed From PB 1. Every location is unique.
