Sorry, VW-1 is about as weak a test as you'll find. If this cable is for use
outside your equipment in the US, the National Electrical Code NFPA-70
applies. I assume you are talking about low power signal cables, for example
NEC Class 2 circuits or ITE limited power circuits.
For lengths greate
It is normal and acceptable for an overload condition to exist on a power
circuit. Examples are motor starting currents and initial charging of power
supply capacitors. Some standards have tests specifically for this
situation. IEC 950 requires that the steady state current shall not exceed the
I worked out what looks like the standards requirements in IEC 950 for
telecom spacings. Do you see any obvious errors in what I did?
The result is spacings which seem excessive to me.

I would tend to discount some of the war stories about low voltage
electrocution. I suspect many are urban legends (invented or embelished
but passed around often and long enough to give some air of authority),
and others have not been given due investigation for such problems
as higher voltage

This is a rough compilation of responses and research on the net.
I do not intend to update or maintain this information.

A lawyer I know (not at Digital) is looking for a
fire investigator and expert witness
who specializes in electrical products.
This seems to be the logical place to inquire.
I would appreciate any inputs
and will collate and repost what I get.

If what you say is correct, you need to contact both Rival and the CPSC right
away. I would also suggest contacting UL (assuming they are UL listed). I find
it surprising that four out of four samples have lethal defects, but the way

You have received quite an assortment of advice and comments over the net. I
thought I would add my recommendation and reactions.
There are two tests you can do to assure the major electrical safety concerns
are met. An insulation test and a ground continuity test. In a service

Does CENELEC have a web presence?
Does anyone have their phone or fax numbers?
