BX was banned from NYC, also in the 70's - it was widely used for that
reason, but NY Electricians couldn't cut the armor without nicking the inner
jackets and shorting it out.
Same few years as aluminum to copper wiring....Homes and buildings  built in
the 70's in the US, NY especially - is often aggravating to RE agents
because inspections reveal these two problems - usually just before closing.
OK, who's gonna pay for the re-wiring job?

>is code in New York...because of rats nibbling on the insulation...
