txsparky: You are very correct regarding no ryme or reason items. Some excerpts from court decisions on the NFPA 70 are: "....no factual data to support this contention." "....no substantiation has been submitted." "....no knowledge of fire loss data to support rule." This one was testimony by a NFPA committee member. So, are some of the sections inserted in the code without anything in support? Yes! Could we do without the NEC? NO! Rowdy
