Wiring Diagram Validation and Questions

[Pavlichenk0]

Hi everybody,
I'm working my way through the education and design portion of the stilling experience, thanks to all of you!

I have a control box partially built, but I wanted to run my design by the group so I can be more sure that it won't light on fire when I plug it in. I don't have any real electrical experience, especially not with 240v mains power.

The controller will plug into a NEMA 10-30R (3-prong) outlet that is protected by a 30amp GFCI breaker in my house's main panel.
The plan is to drive a 5500W ultra-low density heating element with the MoonshineDistiller.com kit: a 30-amp SSR (labeled ZG1NC-240C) and a 500K potentiometer. I want to incorporate a panel-mounted 30A 2-pole circuit breaker, a digital multifunction ammeter, and a hardwired case fan. I have gone through a bunch of threads on here and haven't seen a wiring diagram for this exact setup.

I'm interested to know whether the components and diagram I have drawn (attached) look kosher. I'm also not sure exactly where/how to wire in the fan.

Any advice? Glad to supply more info.

Thanks!
