No not that I have heard of.
Each venue has different supplies available.
I have no idea what size stage show you mean.
Large stages I have worked on had multiple 200, 400, 600 amp fused disconnects to provide show power.
For smaller stages a 200 amp disconect for sound power and a 400 amp disconect for lighting power can handle a fair range of shows. An additional 100 amp disconnect for video and / or rigging motors is a plus.
The only common receptacles I ran into where cam locs and occasionally 4 wire 50 amp outlets.
