Are the various codes for constructing and remodeling houses public documents? Are they available for free onlnie?
For example, adherence to the NM electrical code (http://164.64.110.239/nmac/parts/tit...4.010.0004.htm ) presumably is required by various NM laws, but it appears to be a collection of references to a national electrical code, and I haven't found any online copy of a national code. (I have found offers to purchase it.)
At the moment, my particular question is whether receptacles marked AL/CO are acceptable for use with aluminum wire installed in a house (built in 1964). Various web pages say replacement receptacles should be marked CO/ALR or COLAR, which is a different designation than AL/CO or CO/AL. I understand the material on those websites, but I'm curious what the official electrical code requires.
