Romex (NM) is listed for its use and is accepted throughout the United States. It just happens that IL doesn't allow it in most of their State..
In respect to this, is Romex wiring legal in Illinois?
There are three types of modern wiring; romex, armored cable, and conduit. Most cities and suburbs now require conduit, but allow small sections of armored cable. Rural areas in McHenry, Kane, and Lake Counties still allow romex.
Similarly, is conduit safer than Romex? The NEC makes no claim that conduit is safer than ROMEX®.
People also ask, is Romex legal in Lake County Illinois?
Yes and no - after checking a bunch of regulations and professional blogs and such, it appears - but don't hold me to this, that the cities in Lake County prohibit Romex and require conduit for all wiring over 30 volts like the other Chicagoland counties - but that the unincorporated areas do not prohibit romex.
Can Romex be exposed?
Re: Exposed romex NM cable is permitted to be run exposed on the surface of the building finish. If subject to physical damage then it requires supplemental protection. The term subject to physical damage is not defined by the NEC so it becomes an interpretative issue.
