I have a switch box with 2 - 3 gang toggle switches (for a total of 6 switches controlling 4 seperate bathroom lights, an exhaust fan and ceiling heater. I am replacing them with 2 new 3 gang rocker switches. The old 3 gangs switches have a brass screw on each individual switch for L1 and L2 wires (total of 6 screws). The new 3 gang rocker (Leviton Combination 3 switches) have 3 brass screws for L2 (or out wire to the light source), but only one black screw on the other side marker "Common" for the Live wire. It also has a green screw for a ground wire (which the old switches didn't have. The set up was with the old: blue and white wire into the box. White wire in joining 3 white going out, twisted with a wire nut and pushed in the back (which I won't need to touch). The In Blue wire comes in, wraps around each of the 3 screws (wire stripped only at each screw) of the first 3 gang and into a wire nut. From the wire nut a new blue wire continues to the 2nd 3 gang, wrapping around each of the 3 brass screws (again, wire stripped only at the screw point) before continuing out and up into the wall. All light sources worked perfect... Until I switched the old for the new. I followed the same set-up with the new, only covering all but 2 areas of the blue wire with electrical tape, connecting the blue wire at a the stripped point with Common Screw of each of the 2 new Gang Switches. I also added 2 green pigtails wires to ground each switch to the METAL box. This didn't work. Hit the power at the electrical box and something caused the switch at the main box to trip (a short somewhere). I consulted an electrician friend and he said to replace the old blue wire a few inches from where it comes IN (removing the section of the blue wire that had been stripped to accommodate the 6 screws on each of teh 2 - 3 gangs. I did this and still the switch at the main box tripped as I pushed it back to ON. BOTTOM LINE: Each switch as a wire leading out to the light source/fan or heater. Each has a ground wire from the switch to the box and each of the two gang switches has a live wire connected from the Blue wire IN and continuing out.
Any help, advise, suggestion would GREATLY be appreciated.
