i want to wire 3 outlets for the outside for the house. but i need some help on it. all three outlets are going to be on the same circit breaker. i already have a switch, so that is what i am wirring to. so my real question is how to wire 3 outlets in a row. one box is going to have to two outlets, so a tottal of four plugs, then about 15' down i am going to have another box.
so any help would be great.

switch?? You need a GFI (Ground fault interrupter ) outlet for outdoor plugs. This is the first outlet. All the other outlets are wired downstrem of the GFI plug.
number #12 wire
romex 12/2 (two wires plus a ground)
20 amp breaker

Paul,
I suggest that you go to Home Depot and buy one of the many books on home wiring. They explain it all very nicely with diagrams etc.

Like David said, any outdoor outlet must be protected by a GFI device. You can either replace the breaker that feeds the circuit with a GFI breaker (that would be my choice) or put a GFI outlet in the first box and it will protect the others downstream of it.
