Hi Group,
I'm looking for the voltage perimeters on Class 2 and Class 3 equipment
according to NFPA 70. We have some models that run at 24VAC input power.
Thank you in advance for your help.

If it's got electrical power (e.g. self contained with pumps) try
EN60335-2-40. Otherwise, if it's under 0.5bar gauge there's no

Pressure Equipment Directive may apply.

Thank you, Chris. You expressed my sentiments precisely. While I haven't

there have been many times when I have more than deserved one. Therefore, I
think I would pay my expected dues and feel lucky the outcome wasn't wors
Hello group -
I have another question about equipment for use in hazardous locations. I
find no requirements in any of the relevant standards regarding the proper
colors of indicators (LED's). For instance, a red LED on a standard-use
product could indicate something benign like "battery low" - b
Paul, thanks for the reply. Now, the real stickler for me is that we are
trying to leverage an existing non-I-safe design - the entire enclosure is
plastic. There are materials available with the correct properties but they
are prohibitively expensive, and because the shrink factor is different,

Maybe the only thing in need of calibration here is our collective
conscience and our speedometers.
I thought the purpose of laws, radar guns, speeding tickets ... was for the
public good, not so that we could invent the most clever way to avoid
getting caught. It may be an interesting intellect
Peter:
The best chance to win is through a technicality. Look for errors on the
officer's report; time, date, road conditions, traffic, license #. Also,
there's the possibility that the officer may not show up in court, and you
win by default.
If you search the web about "police radar", you will
Dick,
The standard ETS 300-683 is for Radio Equipment used in short range. Is the
unit described by Richard falls under this category?
