I'm completely frustrated by the re-classification of voltage ratings
in the EU. XLR plugs previously rated for hundreds of volts in
manufacturers instructions are now down-rated to 50v for "domestic
applications". Now I see amphenol AP and EP series are quoted, for the
4 pin, as service voltage 660v, but 50v for "domestic applications".
So is it legal to sell equipment where a 4 pin AP plug carries over
50v but under the service voltage of 660v? Thinking of umbilicals for
valve equipment

Help, please. Andy

If they're to be used domestically, it would seem not. Or can you
read any other meaning into the new ratings?

** Been the rule for a very long time already.

Even the Neutrik " PowerCon " connector (similar to a Speakon but intended
for mains power) is not approved for domestic use.

** You have got a big problem with that use.

The shock risk is with " hot plugging" when the umbilical cable or plug is
defective or the earth pin does not make connection first.

This is not to do with voltage rating but that it locks in place - not
allowed for domestic use.

** Shame about permanently attached power leads then.

Or the locking mechanisms use with IEC plugs.



Now for the reality:


The PowerCon fails basic safety in two ways:

1. It will come apart without the use of a tool and exposes live parts.

2. It is intermatable ( with some force and ordinary wear) with its
ibling - the Speakon.


Total disaster.

Different regs.

Those too would be against regs for UK domestic use.

Now for the reality:

1. It will come apart without the use of a tool and exposes live parts.

Yes - if you unscrew the cord grip and manage to pull out the flex a very
small finger pushed inside the body could touch live parts.


2. It is intermatable ( with some force and ordinary wear) with its
ibling - the Speakon.

Since it's not allowable for domestic use this isn't a problem. Even
although it would take an idiot to force one into the other.

Have I missed something. What the **** does it matter of whether
something is approved for domestic use or not, how in heaven's name
can it ever be policed?

It doesn't much matter if you choose to use them in your own home, but
stops them being fitted to things to be sold commercially - which was the
point of the original post from Andy.

You never know where your home brews will finish up - once they exist
they could go anywhere. I had a word with Iain and it seems hard to
figure if there's ANYTHING the regs will pass for connecting 300vDC.
What a situation!

** OK - produce the reg that makes a latching supply connector illegal in
domestic use.

Yes -


** Lets leave it at that.

Your asinine opinions are not of any value.

** LOL !!

Massive example of begging the question.

What an utter moron.
