This discussion thread has reminded me of my old EE 101? class
some 40 years ago. The textbook was "Transformation Calculus and
Electrical Transients" published by Prentice-Hall in 1949 and last
edited in 1955. Chapter 3 describes the British engineer Oliver
Heaviside who developed the now famous "operational calculus".
When criticized by the mathematicians of his day for not providing
a rigorous proof of his methods, he responded "Shall I refuse my
dinner because I do not fully understand the process of digestion?"
I do not fully understand the vagaries of OSHA and local laws with
regard to ITE. However, I know that with UL approval on all models
we have experienced no difficulties marketing our products across
the U.S. This applies to both the consumer and business markets.

Subject: RE: Query: US safety required for ITE?
Ron, you can break down the requirements into two areas: the consumer market
and the business market. As you have already noted, OSHA regulations governs
the business market. So, all ITE in the work place must be Listed. There are
also some special additional requirements in the earthquake belt along the
west coast, mostly aimed at the physical securing of equipment. For the
consumer market, the state of Maryland has a law in place requiring safety
approvals as does LA, the county of LA, Orange county and San Fransisco. The
latter requires a fee to register your equipment with the local officials
who monitor the marketplace.
I have always heard rummors about New York (city or state?) and Chicago
having similar laws. Once you learn all about this, I suggest that you post
the results.
