Hi All,
I recall Kent Chesley (he can see EMC) saying that controlling emissions is
like squeezing a balloon - you may stop it here, but it may pop out over
there.

hazardous concentrations are expected, then special enclosures must be used.
Look at the typical gas/petrol station - most equipment there is
ordinary-use. Outdoor equipment may require weather-resistant enclosures.
I hope this helps.

Hi Gary,
UL uses a system which I believe is called a Weatherometer, but I do not
know who makes it. As I recall it applies UV and moisture to accellerate
aging due to outdoor exposure.

Hi Barry,
One of my clients makes a charger with primary loop in the base and the
charged unit has a secondary loop to form a transformer, though less
efficient than close-coupled versions there are no contacts to corrode or
offer the possibility of shock .

Hi Ted,
If I recall correctly, another code concern might be that pluggable items are
intended to be accessible so they can be unplugged in the event of fire or
shock. If the outlet is under a floor it cannot be seen, and cannot be accessed
easily for disconnection.

Hello all,
In addition to all of the already mentioned reasons not to use a trace as a
fuse, is that the fiberglass resin becomes conductive once it is molten, and a
"China" syndrome meltdown can occur if the circuit energy is sufficient to
maintain the molten state.

Hi Richard,
First thing to mind is powder coating, where the metal is heated, dipped
into coating particles, and baked, for a very durable finish.
Next thing is Paralyne (sp?) which is a vacuum oven process. I don't know
how durable it is, but it might be worth checking out.

Hi Peter,
We use a Fluke 8010A to measure current directly, instead of voltage. We
have correlated with UL's meters very closely & have had no disagreement
with UL, CSA, or TUV engineers.

Hello all,
Yes, the holes are for retention, and UL498 specifies the holes must be
chamfered to prevent them from cutting off the mating bumps in the outlet.
The holes are optional, but plugs have to pass retention tests either way.
