Basically there's 3 wires running from a 125 amp breaker on the main service. A red(125v) A black(125v) and a white wire(neutral on ground/neutral bar) in main, all running to an older building with a 125 amp subpanel.
At the subpanel the bar that connects the neutral and ground has been removed. All the grounds are on one bar, all the neutrals are on another. The 2 hots are hooked correctly with awg #2. The neutral bar is connected to the neutral wire also #2 running back to the main.
The ground bar is connected to a AWG #2 wire to a grounding rod. So in this particular case wouldn't the bar that runs from neutral to ground in the subpanel need to be connected or something else?
The 3 wires are all #2 and are buried in pvc. not an electrician. but I do understand the basics. Don't need code talk, just regular speak please. Thanks in advance for your help. p.s. There's no water, gas or anything else metal underground near the shop.
