Hello Group,
I would like to know if there is a list of equipment that falls under the
RTTE Directive.
This is in a non-accessible area at the rear of a 19 rack-mount power
supply. Only service or maintenance people can access. Also, the knock out
cannot be pushed inward on the chassis, only outward when the top cover is
removed.

Hello Group,
I have yet another question. Does anyone know what R2D certification is? I
was asked if our equipment has Bulgarian certification for R2D. I am not
familiar with the term.

I've refrained from responding to the ferrite question because of being away
but I would confirm what Amand states. I use powdered iron FT240-43 from

Hello group,
I have a product that uses optional 1/2 half-shear electrical knock outs
for conduit connections. Can anyone direct me to specific requirements on
how much or how little force is required to remove these knock outs? Is a
tool required or not if it only pushes outward?
thanks,

Check out the National Electric Code (NFPA 70) Article 500-7(a) and 500-7(b)

To my best recollection, the essential difference is that Div. 2 is an
environment subject to occasional presence (leaks) of flammable/explosive
gases, while Div. 1 is where this stuff is always present or potentially
present. I suppose this is a simplification, but I think it expresses

Hi Paul,
For wire: CSA/UR Source: type of wire, gauge, rated voltage, max
temperature, flammability rating,
For shrinkable tubing: CSA/UR Source: material, rated voltage, flammability
rating, max temperature, thickness
You should get also a Declaration of Conformity from the cable harnesses'
I would state the requirements (UL Recognized) for the wire, heat shrink,
etc. on the print somewhere. You may want to also set up some sort of
