I recently installed five new receptacles and a new single pole light switch in my spare bed-room. However, everytime I attempt to turn on the light switch, the breaker kicks. The switch is wired to one receptacle in which the feed is coming from the 12/2 black wire. I tested to see if the old electrician used the neutral as the feed (he did not). Any help would be great. I am lost at this point. I have tried everything including a new switch.
