I kept mine rated for 20Amps and out where I can see the wire. I use external fixtures (4-plex) and write on each plug what the amp rating is. Be sure to get plugs and switches rated for the type wire you use, there are different fixtures for aluminum and copper, don’t mix them up. And remember all junction boxes need to be exposed, you can’t hide them under drywall. Huge fire hazard.
