Re: wire guage

I would hesitate to call some of the suggestions 'good'.
The best suggestion was to consult an electrician. <g>
Obvious advice would be to run a 220V feed. This lessens the current draw.
Give it its' own breaker at the main box.
Divide the 220V at a subpanel in the observatory. Insure that it's balanced.
Although there are differing thoughts about separate ground rods, many codes require one ground rod which means that the common white/neutral buss bar in the subpanel needs to be separated. Not all subpanel boxes have this capability.
If you're at all confused by this advice, 'consult an electrician'.
Electrical matters aren't trivial and many people mess them up.

I am a retired home builder and do know the codes. I just

research before starting my project.
