Are you looking for mistakes I made or my helpers? As for myself, I was running the job. My first house wiring job without the boss. Everything was going well as we finished up the job, hanging lights and turning everything on. Except 1 string of lights. Somehow I forgot to hook up 15 recess lights in a large family room to the rest of the circuit. This house was a ranch! No attic. No Basement. Luckily by dropping down the recess cans and a little creative snaking, I was able to run a wire almost accross the ceiling dow to an ative circuit. The same circuit that I was going to hook into in the first place, except in a different spot about 50 feet away from where it was suppose to be. DUH! I always double checked my wiring from that day on.
