Mark, my house is 100 amp service.
My machines are wired for 120, although I have one 220 line out there.(I run the TS off it with the DC)
Forgetting about the costs, filing for a 200 amp service upgrade for me, was not a can of worms I cared to open.(my village frowns upon people working in their garage, so I decided no inspectors for me)
My house was built in 1948, finished in 49 or 50, and from what my local electrician told me when he put in the other lines, they don't permit homes in my village to upgrade, unless its a commercial business.
whatever, my point is that Ive been operating like this with full equipment since nov 2008, and yes, I blow fuses now and then, mostly in the summer with AC's running, but if I keep as much off in the house as possible, I have little problems.
Id love to put in a larger jointer and planer, but I don't have the juice.
you can run your shop on 120 power.
