Re: BEWARE: Ground wires can fail

Max, I should have been more clear. The insulation on the ground wire of all four of my wrist straps failed, exposing the wire inside. On one of them, the insulation is turning into a kind of black goo. It got all over my hands. On the other three, it just loked like the insulation was stripped away, but I surely didn't do that.

I'll send a link when my article is posted.

@Max,

I just needed to use an ESD wrist strap to work on my wife's computer. The insulation in all four of them failed. I'll write up a piece about it (with photos) and post a link here.

@zeglen: A banana plug will fit directly into the outlet ground hole without needing an adapter.

Well, you have to "splay" the end out a bit, and even then it's not a perfect fit -- I think these adapters will do a better job (but they are WAY expensive for what they are)

A banana plug will fit directly into the outlet ground hole without needing an adapter.  It does help to remove the banana plug plastic insulator sheath, not needed in this application.

One possible problem with this approach is that if you cut the banana plug off the lead, you might lose the 1M Ohm resistor (these are sometimes mounted in the babana plug itself) -- that's another reason why Wnderer's solution is favorite.

This is what I was planning on doing (except using plugs that are designed for you to wire up yourself) until Wnderer suggested using the existing banana plugs on the wristbands/mats along with these $7 ground plug adapters.

@Wnderer: Get a powerstrip and one of these $7 ground plug adapters.

This is obviously the way to go -- I'm going to order the adapters right now -- Max

@David Ashton Great little gadget, much easier than my idea if you can get them easily.


Digikey has them.
