Question: isn't it true that in Chicago all single family residential wiring has to be in EMT? No romex, and limited use of FMC is the norm, as I have heard/read. Are they 'safer' because of it? Frankly, this seems an over-design for a residential installation, and no doubt is more costly to install. Still, it undoubtedly provides better physical protection than just romex. Do electricians in Chicago object to this as an overly burdensome requirement of bureaucracy?
