My comment about insurance omitted the word "fire," and it is well known 
by those in the industry. UL and other NRTLs test for electrical safety 
and fire safety, as required by NEC. NEC is a guideline code, written 
and maintained by highly qualified engineers in multiple disciplines, 
and is adopted by nearly all AHJs (Authorities Having Jurisdiction) in 
each city or county. A few cities (New York, Chicago, Pittsburgh, Los 
Angeles) have historically had their own Codes, which are quite similar 
to NEC. In some cases, they are strongly influenced by Electrical trade 
unions to make more work for electricians. For example, Chicago, where I 
lived and worked at the time, required all wiring in steel conduit.

Read the NEC. It's there. In my professional life, I designed and 
specified sound systems for public buildings, and non-listed devices 
that plugged into the power line got the project red-tagged at inspection.
