66', it's cool....
the bonding a both ends was an angle about GEC's as applied to your scenario 250-64(e),if you had been allowed to pass it in one piece thru to the meterbase, our local utility allows this!
250-142 allows you to connect the GEC anywhere up to the service head! It does not directly come out and say this, God forbid any clarity that simple should exist in the NEC! It implies this by way of allowing a dual-usage conductor, which in itself could be run thru the GRC and used to bond it on the way to the panel. At least the way i read this.
Current will follow a parrallel path thru the bonding jumper in the MDP,thru the panel enclosure, thru your GRC, to the trans as well as thru the noodle.
So how does the intent of 250-6 NOT get violated in every service installation?
Of the GEC, EGC , and bonds, i'm not as sure about what item does what job anymore, i don't mean code wise, i mean the hardcore theory.
Case in point;
The Utility here, as many do, tie all the X-formers noodles to a pole ground AND the high side noodle, one big happy ground throughout the line extension covering miles...
I'm not clear as this is an asset or liability in terms of outside influences.
Except when they get to a dairy farm, then there is no pole ground, and a isolated noodle at the trans!!!nothing on it but one line to the farm!
The theory being that only ONE point reference (noodle to earth)is, and works best.....hell we gotta keep them cows happy!
So why can't the same hold true for any other installation????It seems the NEC is bent on having us install parallel noodles!
other threads with individuals well versed in this area have me questioning all the heavy 2-sylable programming out trade seems to be let loose with
OH!, i remember those 3 night-in-a-row gigs!I don't miss em', but i'd still like a crack at that 6-string of yours, what make is it??
