[Elecraft] KPA500 - ground wire between the AC earth and RF output socket

[Mark Bayern]

>>"then the required "green wire" in the AC line should be tied to the
power supply, not the radio.

I think we have missed the point. Any line powered device that has a
conductive enclosure should have that enclosure bonded to the 'green wire'.
It is a personnel safety issue. The KPA500 is line powered and has a metal
enclosure.

I see Jim's white paper does a good job of explaining this <
http://audiosystemsgroup.com/SurgeXPowerGround.pdf>. The grounding
discussion starts on page 10. The bottom of page 11 directly addresses this
issue, but the complete discussion is very good.
