Bill: Thank you very much for this reply. Mr. Wiles came to our town a few years ago to lecture to installers and building officials. I mean no disrespect to Mr. Wiles, but when he spoke he did not make a clear distinction between his opinion and the official language of the code. It took a few weeks to repair the damage done.
I appreciate that you understand that your public stature gives your words authority and that you must be careful what you say.

I believe the truth is that AC cable (aluminum clad) would have to be listed for dc. The NEC is specific about the grounding capabilities of the MC. I am unaware of any specific dc or ac requirements that MC has. There is a possibility that MC may be sold with an aluminum sheath. I'm not sure why aluminum sheathing would have anything to do with how it works, but since AC cable has that concern, this may be what John is referring to. Overall--it is bad form to say that anything is not allowed without specific references regardless of the source. I have made a few false statements in the past and I greatly regret those mistakes. I now try to back up my statements with as much information as possible so that the source of the information is clear. Sometimes (often) I have opinions and I try to make it clear when I am stating my opinions. John has been known to make mistakes. Unfortunately some of his recent articles in IAEI journal have several mistakes which is really bad since AHJs read his articles carefully. Hopefully we can get new articles in IAEI journal that set the record straight. Bill. _______________________________________________ List sponsored by Home Power magazine List Address: [email protected] Change email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
