I sent a request in to the SQ.D company to see if they could tell me what the 20 amp QO breaker was actually rated at. Haven't got a response yet, but obviously whatever it is rated at, on the job in question, it has been holding for 2 years at 19 amps. Of course the 5 emergency ballast that are bad in the facility right now might bump it up a little more, when they are replaced ,( of course I realize the amperage, if any, will very minimal). I've sent my information in, to my customer, and am waiting on their reponse as to what they want me to do.
I've also sent "South Wire" (one of the manufacturers) an email to see if they could actually tell me what #12 thhn is good for, before the insulation actually breaks down in real life, in their test labortories. Still looking for their response also. Thanks again for all the response.
