Ok, guys, are dealing with 2 different service types, 120/208V 4w WYE connection, and 120/240V 4w DELTA. A 120/208 service the voltages are 120 degrees for the phase angle on each phase (example of phase angles A-120 phase, B-204 phase, and C-360 phase). in a 120/240 delta the single phase load...

Also look at the NESC book for their guide lines, this is where the utilities get their standards for everything[morning]

an easy phone call can solve this, to me

is this a 200 amp service, that makes a differences in meter types. we'll start with this question first to get the right answer

As a distribution lineman for many years, we have always used, or installed a pole ground and bonded at the neutral, than installed a ground wire on the under side of the cross arm for the ground side of the arresters. this allowed for a short jumper wire from the line to the top of arresters...

once again some one does not understand the voltages of a 120/208 3 phase system, and has them mixed up as a 120/240 single phase system, the same people that believe you can have 120/240 equipment work on a 120/208 and than ask the utility why the voltage is low and not 240 but at best 216...
