Completing an electical circuit

I am wiring a circuit in my new garage that consists of several outlets. The hot cable comes into a outlet in the middle of the circuit and then outlets extend in both directions around the room. I have connected the three cables to the outlet to which the power comes and can only get live outlets in one direction at a time. How do I hook this thing up so that I can get all of the outlets to be live at once? Do I need a special outlet to do this or will a conventional "plug work?

 

We'll presume you are installing receptacles outlets and are using 2-wire cable between the receptacle outlet boxes. If my understanding is correct, you have a 2-wire "feed-in" and two 2-wire "feed-outs" at the "middle" outlet-box. At EACH outlet-box, using "side-cutting" pliers, twist the ends of the Black wires together and then twist the ends of the White wires together. Energize the circuit and test for voltage, Black-to-White, across the Black/White connections at each outlet box.If each box indicates voltage, then using stranded Black and White wire for flexibility, connect 6" leads to the receptacle terminals,wrap electrical tape around the receptacle terminals to insulate them, andwire-nut the receptacle leads to the wires in the boxes.-----GFI protection is required for garage receptacles,so you will have to connect a GFI receptacle at the box with the "feed-in" cable. Make this connection ONLY after you have completed all the other receptacle connections and have tested each receptacle for voltage.The 2-wire "feed-in" cable connects to the "Line" terminals of the GFI receptacle, and the two 2-wire "feed-out" cables connect to the "Load" terminals.----Good Luck!!!

 

I don't know how you were able to connect 3 black and 3 white to the first recepticle. You should connect the 3 black and a pigtail with a wire nut. Do the same for the whites. Connect the black pigtail to the brass screw and the white pigtail to the silver screw. Connect all the grounds with a green nut and to the ground screw. At the other outlets connect one black under each brass screw and one white under each silver screw.
