Advice on a power supply umbilical needed.
 

True, but if the connector is *within* an enclosure that needs a tool to
open it then the 50V limit does not apply, even in domestic use.

David.

thanks David - that's worth knowing!

Anyone can poke a bare wire into a mains outlet and get fried.

You're posting to a civilised country where mains outlets have shutters to
prevent this.

For least noise you need to be carrying your grounds to a single star point,
which then connects to the chassis at a single point. That makes sure
that ground currents can't generate any voltages in the signal path.
Careful ground design allows you to use a single chassis quite
happily.


Exactly as you describe!


Brilliant, then just bolt them together and hard wire the connection.

Never mind all the useless technowanking, Andy - I gave you a couple of real
world, useful suggestions. Have you spoken to Phil at Bluebell yet? If
anyone knows how to daisy-chain 500VDC boat-anchors in the UK, he will.

While Cliff UK will almost certainly know who's got 500VDC 'touchproof'
connectors available - if, indeed, anyone has at less than *industrial*
prices....

So, jump about a bit Andy and let us (me) know how you get on - in all the
crap that's flying about in the group atm, this is something real that might
just be handy for someone else in the future!

:-)

** Fraid you have got the whole DAMN ISSUE WRONG !!!

It is **NOT** a simple connector choice issue.

The clueless ****ing OP is asking the wrong question.

Try reading my post on the matter.

OK Phil, I just did and I think I see where you're coming from - the 'live
chassis' possibility is where it hangs, ain't it? And the difference is my
250VDC* 'umbilicals' are going to *PCBs* as per:

(I really have gotta start reading posts if I'm going to respond to
them....)

Andy, still speak to Phil at Bluebell - he's still the guy who'll know if
what you want to do can be done at all safely!


*still not an inconsiderable tug on yer bell end if you let it touch! :-)
