Use #4 AWG ground wire for non EMI/RFI protected systems, installed in the United
States. Use Alpha #1239, 1-3/8” flat braid or equivalent for EMI/RFI protected and
CE marked systems. The total length of grounding cable must not exceed 10 feet (3
meters).
After grounding the overall resistance must be measured. The resistance for the
equipment ground to the grounding electrode must not exceed one ohm (1
Ω
). Check
the effectiveness of grounding by attaching a wire to the nearest grounding electrode
and connect an ohmmeter in between the reference ground wire and the enclosure.
