I?m new here and haven?t been a journeyman for all that long. The company I work for took on some fairly large projects and I finished one shop and office building. I am now in a situation where I have had to go take over a half finished job from another journeyman who is causing problems with the other crews. He is highly skilled at talking and overcomplicating things.
Now I went and listened a bit to long and he has my head turned around on a few things.
Wye system
I?m installing a outdoor transformer + ground rod/ utility voltage to 480v 600a
Outdoor Auto transfer switch with a main disconnect and a bonding jumper setup + ground rod
Outdoor distribution panel 1 400a breaker for the offices and 1 200a + ground rod for a whole bunch of pole lights
Inside is a 480/277 lighting panel
75kv transformer Will be bonding in the transformer.
2 208/120 panels for general power.
I was going to parallel grounds, hots and neutrals from the ATS where the bonding jumper is and then bond the cold water, gas and building steel to the panel inside.
He?s telling me I ?have" to use the cold water pipe ( copper ) as a grounding electrode and building steel as well. I was planning on running my ground back to the ATS and hooking to the lugs were the bonding jumper is and the ground rod there.
Any help will be appreciated. I think I?m going to have to get the grounding and bonding series.
