<p>I DIY electrical work only with the following: replacing old components like cgfi, outlets, installing ceiling fans to prebuilt outlets,… I think electrical codes are confusing and stupid and don’t DIY on new wiring. I understand the difference between an electrical engineer and an elecfrician. I only know the red and black wires in my lab.</p>
<p>I fixed my car air conditioner in less than 5 minutes without buying anything. The car repair shop wanted $1200 from me. And this was electrical and mechanical work: the little screw inside the control knob needed to be tightened. :)</p>
<p>I fixed my car two years ago for three dollars and a repair shop would have charged over a thousand. This was when a flying object hit it, dented it and ripped off the entire bumper.</p>
<p>We just installed a ceiling fan here a few months ago and new motion censored lights outside</p>
<p>I had an additional loss of $8 when I replaced my outdoor lamp. It worked at the time I installed. Sometimes later my wife said it did not work. I went out and checked again and found nothing wrong with the circuit connection and decided to buy a replacement bulb. After I put the new bulb in, it still did not work when turning the switch on. Later I figured that light would turn on only at night. I almost blamed on the cheap Home Depot defective lamp. Ouch!</p>
<p>Very clever test method, although not completely accurately described by the leviton product manager…I was about to say that he couldn’t be right about it, but he is right that you can test it in an ungrounded situation…it just doesn’t happen precisely in the way that he describes (he leaves something out).</p>
<p>If UL is ok with that test method, I guess its OK. And it confirms that they contemplate that the GFCI outlets might be used in ungrounded boxes.</p>
