It won’t be on Amazon, but I found a ton of older generation Mac minis available on Craigslist in my area. I picked one up for $50 and installed Ubuntu server. Thing’s been running like a champ for 2 years.

Edit: should have fully read your post. No idea about installing truenas on it. I’d assume most would be single ssd machines.

Ok, cool. So if the romex is rated at 15A then I’m going to assume that’s the rated safety limit before things start to get sketchy.

This panel is going to provide 1200w at (I’m assuming) 120v which is 10A.

At that point I plug in something that pulls 1500w (120v for 12.5A total) like a hairdryer.

You’re saying the load on the circuit breaker will be 1500w-1200w for a total of 300w (2.5A), correct? The load on the romex in the walls after the breaker will still be 1500w (12.5A), correct?

What happens if I then plug in a space heater on that same circuit which consumes 1500w (12.5A). The breaker load should then be 15A (the net 2.5A + 12.5A) as it’s rated for and shouldn’t trip, but the load on the romex after the breaker would be 25A (12.5A + 12.5A), 167% its rated capacity.

Am I misunderstanding something? I’m honestly not trying to argue. I’m trying to understand.

Yes, I was conceding that point. I was then worried about the actual romex in the walls entirely contained after the breaker. Are you able to pump as much power as you want at 15A on a 15A rated wire? There’s got to be some limit, right?

Idk man. It’s probably over my head but I still don’t think the wires themselves could take it. In my thought process you’ve got more electricity flowing around on the circuit and even if it gets used before getting to the breaker things are going to be heating up pretty quick.

To me it sounds like trying to hook up a power plant to a data center via an indoor extension cord. It’s gonna melt.

His point was that if you’ve got 1200w incoming from the panel then you only have 300w of overhead on that circuit before the circuit breaker blows.

Sure, it’s within the limit on its own, but without a dedicated circuit for it you’ll be blowing a fuse pretty frequently when trying to use nearby plugs and lights.
