i am in washington and two ground rods are required by WAC (washington administative code) unless you pay to get an engineering report testing the ohms to PROVE you have 25ohms or less and even then the AHJ's dont like it and you have to go to their supervisor to get a blessing...not worth the hastle.
george the garage will have little load on it lights (some flourescent mostly incandescent) few plugs for power tools 120 volt(drill,saw ect...)garage door opener.
and a small office in it more plugs a 2000 Watt heater and a computer in it. maybe a future rv plug down the road. are harmonics going to come into play here?
the gec will goto the ground bar(floating neut) in the panel with the rods and building bond, is this what they mean single point grounding?
if buss is rated at 75 degrees then its ok,
how/where is that listing?
thanks again guys,
