Is it legal to make a custom slip ring?

It would be an interesting way to get around the 30A limitation! Not really convinced the GDC would think it legal, though.

R50 Branch circuits may include intermediate elements such as COTS connectors, splices, COTS flexible/rolling/sliding contacts, and COTS slip rings, as long as the entire electrical pathway is via appropriately gauged/rated elements.

Seems like it would be legal with 12 AWG elsewhere. The downside is there would be no contacts available for any kind of speed measurement for a motor on pivot swerve.

I spent sometime looking at these, and decided a coaxial swerve was a simpler approach from my viewpoint.
