Is it ok to use a 220V feeder to a breaker box and then feed out through independent breakers from there? That may get around the problem, but I can not say for sure. I have a breaker box in my shed that is fed from the house.

Otherwise, you can just run 2 feeds in the same conduit for just the cost some copper and a 2nd breaker.

Off the topic, in a magazine article that I read last year, there was a comparison about best heat sources for workshops.
The answer made a lot of sense to me.
They said a high capacity propane heater is a good solution because it can heat everything up very quickly (if you size it correctly).
This makes a lot of sense in a location where you are there less than 50 percent of the time. You can turn it on, and it will be heated up and ready to go in 30 minutes (so you don't have to wait or work in the cold), and you don't have to waste all that money keeping it heated for all this extra time when you aren't out there.

I have a breaker box in my shed that is fed from the house. The total load in your sub-panel (the breaker box in your shed, for example) will determine the size of the breaker in your main panel and the size of the wire that feeds the sub-panel. You can not, say, use 10ga wire coming from a double 30amp circuit breaker in your main panel to a sub-panel, and then use more then one double 30amp breaker to supply multiple circuits. Because of that, there is no point in having a sub-panel in that case. You must use the right size wire and circuit breakers to support your total loads. Codes may vary from state to state. Best to ask a local qualified electric contractor.

You may do so, but be advised that burning propane creates A LOT of moisture.

obviously the wires must be the right size.
You can still trip the main breaker in your house without trooping any others.
As for moisture, it does create some, but around here if it is cold enough to fire it up, it is usually pretty dry anyway.
