15 amp circuit VS. 20 amp Circuit

Have you measured power consumption of components????

Ratings are not helpful sometimes when it comes to how much Power usage there would be

Same leg of power? That's a multi branch circuit. The best have individual circuits if you can have room on your panel.

I hate multi branch circuit terribly sloppy

@joshziggie2021 AI also says if a shirt takes 3 hours to dry in the sun and pants take 4 hours, then 2 shirts and 2 pair of pants will take 14 hours to dry 

If you have a 200 Amp service in your house, each leg has a capacity of 100 Amps. as long as you don't overload that leg by wiring it for more than 100 amps total, you have no issues. If you have a 400 Amp service, same story, only 200 Amps per leg. if you do as the AI says, you stand a much larger chance of having a voltage differential between neutrals with resulting hum and noise issues. Conventional home wiring was never intended for applications that shared neutrals or grounds across different bus legs.

An AI only knows what it has been taught from it's model. AIs are incapable at this point of creating an original thought, like when to use a parallel process vs. serial process when solving our solar dryer question. Or inferring that minute voltage differentials when loads have different neutrals or grounds will create a differential noise level in a complex audio system.
