If you do the job yourself, you're probably looking at somewhere in the ballpark of $500-1000 in materials. But there are a lot of variables involved in this, so it's hard to really say with any...

Steve, a couple clarifications:

1) standard receptacles can ONLY be fed from 20A or 15A breakers. You cannot directly feed a receptacle from a 30A or larger breaker. I only said "30A cable"...

Ah, OK- you only really need a single 20A circuit going out there, which fortunately for you, GREATLY simplies thing, and were likely recommended to use 60A (#6 cable) for voltage drop. That's OK,...

The outlet will come with directions- it should be pretty straightforward; you'll probably also need to add a pigtail to the whire wire, so see if you can scrape up about 6" of #12 from someone. The...

What all do you intend to put in this hobby shop? Is it just going to be some lights, some receptacles and a couple light woodworking tools? Or is this going to be some full-up workshop with...

The service is independant of the breaker panel. You could very well have a 200A service with a 150A main breaker. But it will at least give you a good idea!

If you can plug that freezer into a wall socket, it's only 15A. 20A appliances have special plugs that don't fit standard receptacles. A 15A circuit with #14 wire is fine for this. That said, if...

How fast is the breaker tripping? Is it INSTANT, or is it a few second pause? If the former, it's a short circuit- your pump is toast. If the latter, it could just be a locked rotor; see if you...

Good point about the surge suppressor! I'd forgotten about TVSSs- they most definitely do not work on ungrounded GFCI outlets.

I agree with you in principle, but in practice, the case floats close to ground and 100BaseTX and other residential communication lines work just fine. More sensitive serial connections just aren't...

There's no real requirement, but 48" is usually a pretty good height. (ADA allows a max of 48" for handicapped accessibility, IIRC)
