Yes... Yet another 'I need powa in my pole barn' thread. I've read all I can and I have some questions.
Typical setup (somewhat), running a 100amp supply to a pole barn. The pole barn is 50' from a typical old style barn which has the main 100 amp panel in it. Think of the old style barn as a house supplying the power to the sub panel in the pole barn... Ran a 2/2/2/4 mobile home feed to the pole barn from the barn. The 100 amp main panel has only been installed for 5-6 years and was inspected when it was installed.
Ok, the main panel has the bonding screw screwed in. The ground and the neutral are tied together in the meter base and all of the neutrals and grounds are intermingled within the bus bars (as I call them) in the main panel.
So, the bonding screw in the sub panel DOES NOT NEED TO BE SCREWED IN... Correct? All of the grounds need to be on there own bus bar and all of the neutrals on there own bus bar, correct? The ground bar should be grounded to the sub panel box, correct? This keeps stray current/volts from getting to the bare ground in the case of an issue, from what I understand.
Does the sub panel need its own grounding rod in the ground? Ive been thinking no, thats the reason you ran the #4 ground wire but were getting conflicting recommendations here.
