15 amp bath fan?

I am wiring my kitchen and I did not pay attetnion to the location of the wires prior to removing them from the ols outlets. Can anyone help?? I have three wires (white, copper, black) coming form the FUSE box. I have the white and copper hooked up to the ground. That part I think I got right. The first box it goes into has a total of three sets of wires coming into it. I need to put an outlet in this box. One set of wires goes on to other outlets that I havent "messed" with. The other goes to a single outlet that flows on to one other outlet. The second box also has three sets of wires total in it. One goes onto another Non-Messed run. Can anyone tell me, or better yet diagram, how the wires should be pigtailed and hooked up?? When I hooked it up today I can tell something aint right! I heard it buzzin. YIKES! Feel free to contact me on MSN (Eagle56755@hotmail.com) messanger.

Next in the saga of wiring a pump control box: The metal control box chassis has TWO green screws which must be for the EGC. Question is, should I pigtail a EGC wire via a wire nut joining the line and load EGCs so there's a continuous EGC connection between line side and load side with the pigtail grounding the box via ONE of the green screws...OR...is fastening the EGC coming from the pump to one green screw, and the EGC to the pressure switch to the other green screw sufficient? In the pressure switch, seems like it's designed to be done the second way (no pigtail), since there's very little room in the pressure switch housing for a pigtail, and TWO green screws are provided there as well. I've only ever wired recepticles and switches with plastic boxes, where I always provide continuous EGC and also pigtail to the green screws on the outlet or switch. So the general question is, are metal boxes considered a sufficient EGC path?
