[Elecraft] Grounding negative side of power supply?

[Don Wilhelm]

Guy,

That is the reason I put a perimeter wire around my house with a ground 
stake every place the wire makes an abrupt turn.  That wire provides any 
lightning surge with a lower impedance path than that which it might 
find by blowing a hole through the foundation wall.

In my opinion, definitive information on lightning protection and 
station grounding was written by Ron Block, and can be found on the 
PolyPhaser website - it was also published in a 2 part series in QST 
some years back - it should be available to ARRL members on the ARRL 
website.  Those articles convinced me that the perimeter wire was the 
best thing I could do.

73,
