Problem with low voltage in garage ???

i would like to know if this is correct i plan to wire my shed it is about 100 feet from my house i plan to use a 30amp 2 pole breaker in the house and run 10/3 with ground out to a 70 amp max (got this for free) box this box holds two breaker slots i plan to use both . i want to put 2 - 20 amp breakers in the box to establish 2 circuts one for lights and one for four recepticles is i plan to run a ground from the box to the ground i dont plan on using anything big just some simple power tools and a couple small saws is this right

Hello, I maintain a 3 unit bldg. There are 4 electric meters (3 for the apts and 1 for the bldg). The last guy wired it all wrong -- 2 apts on 1 meter, 1 apt and the bldg on another, and 2 meters not connected to anything. He installed a nice new clean shiny breaker box that only allows for 2 feeds -- that is, there are only sections of breakers, hence a wire from meter 1 goes to half the panel's breakers and a wire from meter 2 goes to the other half. My question is: Can I find a box that has 4 breaker sections or should I add a second box with 2 breaker sections, leaving the first one intact? I suspect a 2 section box will be less expensive, but then I'll have the difficulty of running the feeds from the meters to 2 separate boxes. And, can someone point me to a place online that sells this stuff? Thank you, Joseph R. Skoler [email]joseph@compuhelp.com[/email]
