Copper Sleeve over IEC

Sabai, so what is the probability of success? And who is most likely to have it?

So, I just inserted a thin piece of carbon fiber inside the copper sleeve...

Though I had high hopes for the carbon fiber insert, to me, it was not an improvement.

I suppose I'm the only one using 3M AB5100S.

What do we think is being done with the copper around the IEC? I bought a leakage meter, and found that I had none before and after I installed copper around this connection. I heard nothing either.
