[Elecraft] I need some grounding-strap guidance, if'n you please

[Bill Maddock]

David,

   As a correction, all conduits are to have a green grounding
conductor included per NEC. This was changed many years back in
thee NEC because it was found that conduit may not always
have a good ground all the way back to panel due to loose screws
corrosion etc.
