Blowing Circuit Breaker

I've recently installed a new porch light outside. The problem is everytime I turn the switch, the circuit breaker turns itself off. Now let me tell you how I did it and please review and give all advice you can because I'm confused.

I stalled the new light by pig-tailing off an existing receptacle. I pigtail black to black, white to white ground to ground (@ receptacle); than, I pigtail the same @ the switch than connect from the switch to the light fixture. All this using existing 20 amp circuit & 12 gage wire. note: the existing circuit has 8 existing receptacles attached.

No matter what I've tried, I keep blowing the circuit. If I take the switch off the new lights, all the receptacles works just fine. I've checked for loose wire connections and there were none. I don't think I am over-loading the circuit since the township resident electrical inspector said " you allowed up to 12 receptacles (using 20 amp)"

Can anyone shed some light to this dilemma? Do I need to rerun a new circuit just for this "1" outside lighting lamp?.

It sounds like you have the switch wired across the line instead of in series with the load.

Try this:

At the switch you do only switch the hot (black) wire. You run the white wire straight through unswitched.

Jughead's picture is correct, but unless you hyave a fabcy switch you only need one wire nut at the switch, to conect the two white wires. The black wires should connect directly to the screw terminals on the switch.
