I went through it a few months ago and for California, at least, the only restrictions were a 2-year limit to be on it, you have to check in weekly to attest to regularly searching/applying, and that you were ‘let go’ through no fault of your own. (i.e. quit or fired)
To add, they will generally set up an eligibility interview over the phone with a social worker before any decisions are made.
I would also suggest to apply for health insurance through the ACA’s website as it takes a bit of time and you don’t want to be stuck without and get injured or with a penalty. (if mandated by your state) It’s generally at no cost if you don’t have an income and can be canceled when you do.
They could actually get a bit warm with carbon steel being more resistive than copper. It would depend on the draw the engine uses to turn over though.
