Electrical codes (laws) vary a bit from one place to another, but nearly
all are either based on the National Electrical Code or are quite
similar to it. Some with strong unions require that all wiring either in
steel conduit or an armored cable called BX that can be fished through
walls. Here in California, and in most of the rest of the US, Romex
(three conductors in plastic sheath) is nearly universally used. There's
even a hardened version for direct burial!
Years ago, My daughter bought an old house in Chicago, and I hooked her
up with an electrician who was able to rewire it by running conduit on
exterior walls and through the basement. In an old building (built just
after the Great Chicago Fire) I bought there, I had it rewired from the
attic over the second floor and the basement under the first floor. In
both cases, two-conductor wire and outlets were replaced by three wires
and three-wire outlets. In the process of doing a minor remodel, my
contractor pulled out most of the original gas lighting pipes (although
on the first floor, they had been used as conduit to carry wiring for
those new-fangled electric lights).
