Know what I mean sport?

A plug with no live or neutral connections but a solid connection to the earth pin.

I can find plugs that have a high resistance earth outlet for static control but nothing with a solid earth.

The only one I found was this one from Groundology:

Silly money -- because the market it's designed for can withstand it! -- but it is well made.

[Sam Spoons]

My inclination would be to make one from a standard plug top. Maybe encapsulate the live and neutral pins internally in epoxy so there is no risk of the earth wire becoming detached and making contact with the live?

I do have slight reservations WRT safety so what does the 'hive mind' think?

Yeah, 'I' could do that but I want the information for a very 'newb' person on another forum and a US (I think) mains supply.

[Sam Spoons]

Definitely a 'point him at the Groundology website' situation (assuming they do US plugs).

But, are US mains installations routinely 'grounded'? Outside my experience but if not ...

I did make one for exploratory use, although I consider myself an experienced user. That idea about epoxy is probably a sensible one for general purpose safety though.

I just followed Hugh's tip and used a couple of rounds of heatshrink.

[Sam Spoons]

Good idea, though TBH you could probably cut the L and N pins off at the end of the insulated part...

[MOF]

You could use a child safe ‘dummy plug’ and replace the plastic earth pin with a brass one.

[Dan LB]

Have someone 3D print some dummy live and neutral pins in plastic for the specific plug type and roll your own.

[MOF]

Most plugs, if not all, have removable live and neutral pins, so do that then the earth pin will locate the plug securely. I don’t know why I didn’t think of that first.
You could use the plastic pins from the dummy plug I mentioned first to glue into the holes left by the brass live and neutral pins.

[zenguitar]

I came here to point out exactly the same thing. It will plug in with just the earth pin. No live or neutral to worry about.

[Sam Spoons]

Ingenious, and obvious when you say it out loud :clap: :clap: :clap:

Now, the guy Dave is trying to help may be in the US which would change things a little. However I will probably make myself one using that method. I like the extra rigidity having plastic L&N pins would give though they are probably unnecessary.

Just a thought, those flat fronted socket blanks would work but the pins would be a little short.

[ef37a]

Yeah, hmm, see I don't really want to suggest the guy MAKES anything because he has no electrical knowledge AFAICT and I am after all suggesting he sticks something in a POWER socket!

Thank you all for your interest and suggestions though.

Dave.

CPC sell the yellow plastic grounding plugs in different versions, 0 ohm or including 1M Ohm resistor, Stud or binding post.

Somewhat !

CPC are Farnell and might have a USA option in their USA store.
I got "Access Denied" when I tried to look.
