Mike, regardless of what the NEC says, and it is not very clear in this
regard, it is the state, county and city electrical codes and other local
regulations that apply. Many jurisdictions have deviations from the NEC
and/or have other regulations that require electrical equipment sold to the
general public be Listed. I know of the following locations: Virginia, North
Carolina, Los Angeles, Counties of Los Angeles and Orange, and San
Francisco. I have also heard but cannot confirm that other locations include
Oregon, Washington, New York city and Chicago.

Subject: NEC Question



Can someone point me to a section in the NEC that says a piece of
RESIDENTIAL computer equipment must be "listed" (NEC definition).  Article
645  which requires a "listed" piece of equipment appears to apply to a
computer room and not a residence.

Basically I've been asked where its says a piece of computer equipment must
listed/approved by a NRTL.  I'm ignoring the obvious liability implications
should someone get injured for the purposes of this question..

Any help is appreciated.
