Is there ever a time where a MAIN PANELBOARD for a Sinfgle Fam Dwelling would NOT have a #4 bare ground for cold water ground? copper piping.
here in Arkansas the GEC goes from the Ground rod to the METER BASE. In Kentucky it is from the Panelboard to the Ground Rod. If there is a copper water line, you need a COLD WATER BOND..usually a #6 for 100A and #4 for 200A this ALWAYS goes to the MAIN PANELBOARD..
i saw a house today that only had a gec from the main disc at the meter..no other ground in the panel..
this looked wrong to me..
the feed was a 4 conductor SER type cable..
thanks for any replies..
