Starting a project without a complete plan is very risky. Let's hope you get really lucky and are able to utilize the work you've already done.

Exactly what kind of cable did you bury and how deep did you bury it? Does the barn have any electrical service currently?

You need a double-pole 30-amp breaker in your main panel. Let's hope that 30-amps is enough to run the 240-volt tools you want to run. It's enough for some of them, but not all of them.

You'll need a subpanel and a grounding rod at your barn. Almost any kind of subpanel will do, but you may need to buy a add-on grounding kit for it. If you need more than six circuits, get a panel with a main breaker.

There's a few hundred other things you need to know, but let's take it one step at a time.
