@jnrollins: Thank you for your thoughts!
Lol. My soulmate. 
Any of my projects that stay attached to power are attached to smart plugs for the same reason.
No. I do not, but you never know, when some stray bit is going to toggle a smart switch or outlet. I went with reset-able fuses and I definitely plan on checking their trigger point as well as my clamp ampere meter.
I found the specs and they recommend no more than 5A per panel, which is about 40%. I had them way up to test, and they literally almost boil. I quit at 200 F.
I had to take a little break because I got some total crap wire from Amazon, and have to replace it.
Any way, this is what I decided on, but I’ still like to hear some ideas…
Edit 1: I haven’t added (or even tried yet) the display and encoder switch that @blazoncek suggested here.
