Blk , red , white = 4/0 ,.. bare = 2/0 What is the purpose of such a large bare conductor ? Am I not seeing something here??
.. Main disconnect is a pole mount 200 amp meter/main combo .. Main feeder to the single family dwelling = pipe underground with 3- 4/0 dual rated USE/ RHW and 1 copper #6 thhn to a big ol'e PVC J-box then changes over to the above mentioned SER cable . The grounding electrode is 3 5/8 x 8' ground rods at the pole.. # 6 thhn loops the 3 of them.
???? was the # 6 equipment grounding conductor sized correctly for the feeder?
???? when does it make sense to have a 2/0 bare conductor ? three phase service I guess , and the bare as a grounded?
