If grounding should be done in a low impedance fashion why do I always see
the service entrance ground on homes to be nothing more than a AWG#4 wire
about 5ft long from the service box to the ground rod embedded in the
basement slab?
The cable company ground to the same ground is just a length of bare #12.
I'm asking because I'm getting ready to properly route two antenna coax runs
to the service entrance area where I'll mount the bulkhead plate. I wonder
if I should do something fancy for grounding the bulkhead like a 2" wide
solid copper strap or just run a #4 wire to the same ground rod with the
same sort of clamps.
Or should I embellish the grounds from the existing power and cable
entrances in some fashion?
FWIW I'm in Baltimore County MD if that makes a difference in applicable
codes.
thanks
