Any one know about wiring...

I am trying to set up my old grain shed with power. Any one know about wiring, more than just a switch and a light. A switch that controls 3 lights with 2 constantly hot sets of outlets...

You will need 3 conductor cable between the switch and the second outlet. Start at the breaker box with 12-2 w/ground
and wire first outlet as usual, bringing another 12-2 out to run to switch. At switch, black hot goes a pigtail with a
short wire to one side of switch. White will get connected through. From switch to next outlet, use 12-3 w/g. Switched
hot can be either black or red. The other will be always hot, and will also be pigtailed into the hot that came into
the switch. It would be easier to draw it!
 
TOUGH ONE!

So, you have power comming into the grainery., and, a light switch to turn on/off a couple of lights.

What it the "goal" to expand from your drawing? Maybe a motor activated devise, or more lights?

Years ago in our barn, we had a single light bulb and hand shoveled the graingery into "granny bags" wheat, barley, etc.

The grain shed is a detached building. Most places require a sub-panel installed for this application. If that is all you think you will need you might just put in a small breaker box and run 10 gauge underground feeder wire to the box. You might as well put a 30 amp breaker in your main breaker box and run 220v to the sub-panel. You will also need to install an earth ground rod and run a #6 or 8 solid copper wire to the rod. On a sub-panel you keep the neutral (white) wire separate from the ground (bare or green)wire. Then for the outlets you might use a 20 amp breaker and 12 gauge wire wiring both outlets to the one breaker. Then for the lights you could use a 15 amp breaker and use 14 gauge wire or you could use a 20 amp breaker for it as well and 12 gauge wire. Run the wire to the switch and attach the black wire to one pole on the switch and run another wire from the other pole on the switch to the lights From the switch the white wire should be wired directly to the white wire going out to the lights. Just run out to the nearest light and from there run another wire to the next and then to the other. The black wire is the wire with the power. The white wire is the neutral and the bare wire is the earth ground. Bond the boxes if using metal boxes and the body of the light fixtures all to the earth ground wire.
 
Using 2 wire with ground @12 romex wire, for the outlets, run the electricity from inside the box as follows. Put a
romex connector (strain relief in the knockout at the box near the circuit breaker you want to use. Attach the white
wire to the neutral bus screw. Attach the black white to the circuit breaker (probably 20 amp). Attach the green wire
to the ground strip. Leave 6 inches of slack in the wire inside the box. Use wire staples, drilled holes, or support
clips to hold the wire in place along the wall at the height of the outlets above the floor. Attach the wires in the
duplex outlet (20 amp rated) with black on the bronz screw, and white on the silver screw and the ground to a wire nut
that will have a short connection the the outlet ground and continuing to the next outlet. Attach the second outlet box
to the first one using the second set of screws in the first outlet. Wire it the same. Run the wire over the door not
under it. For the lights, follow the wires from the outlet from a second breaker (15 amp) with connector at the box.
At the light switch connect the white from the input wire to the white to the first light. (use a wire nut) the black
wire should be connected to the switch terminal. The black wire to the lights is connected to the other screw terminal
on the switch. Grounds are connected to each other and with a pig tail to the switch ground. Run the light wires from
one light to the next following the fixture makers directions (I recommend LED fixtures that look like flourescent
lights). Make sure all are grounded to the fixture with a pigtail. Jim
 
What is available at the breaker box, 220 at 60 amp, or what?

You can wire 120 across to the receptacle, the switch, and the other recepticale, but if you plug in big loads the lights will flicker.

Would be nice to have the lights on one circuit, and the receptacles on another. Or even have the 2 receptacles on 2 different breakers, so you
can run a good load on each.

What all is your use here, what is the plan?

Not knowing your experience with electrical, there is a lot of good advise here, but unless you "speak the language", there is a lot to digest.

My suggestion would be to purchase a "how to" book with illustrations and glossary terms.

That way you will get the big picture before you start. Then make a detailed material list using the correct names for each component.

Knowing what you want when you go to buy supplies makes a big difference in the help you will receive from the supplier.
 
HD, Lowes and Amazon have "how to" books You want to do it right so when an electrician looks at it, it will make sense. What you are
doing is basic home wiring, but you should have some idea of how many amps your are going to be using. If you are going to want 220, I would
recommend a sub box in the grainery. You said "shed", If it is going to be exposed to weather you will need to use something other than
romex, conduit or UF. I would put UF cable in plastic conduit to protect it from bumps and moisture.
