you cut that pin off to seporate your gear from the electrical system

have a tie to the electrical ground you have two different potentials
meeting at your gear. Besides the ovious dangers, you could have
several volts difference being created on your ground potentially
causing other fun problems.
Tom, are you asking--SHOULD you cut off the 3rd pin on your AC plug?
No, you do not. From a safety standpoint, a big no. I can explain
further if you like.
As far as building tops, I put quality surge arrestors on ALL
wires/cables leading in or out of the cabinet, and mount the arrestors
on a separate single-point ground plate or bar. Ground the plate to
building structural steel with one or more heavy >6AWG cables, and
bond the equipment cabinet to the plate. That's the simple version...
Happy New Year!
