I am a liscensed electrical contractor and have much to learn but common sense tells you when something just isn't right and I do have the sense to seek a higher source e.i. NEC or fellow electrician . I think to many handyman assume to much because it worked before and seem to rely on HD or Lowe's to answer their questions. I dread walking through the aisle overhearing them explain something to a handyman or even a homeowner. I also wish a homeowner would think it through when it comes to dollar signs. A true electrician might charge more per hour but almost gauranteed to get out their hair much faster and with a safer and better looking job. I will admit a handyman has his place but most don't know when to say, "you need to call a pro."
