Current subpanel was installed in the early 70s. We think we need to replace it as lights are not working (very dim, flickering/fading in/out) - we suspect an open neutral.
How do we wire in a new panel? We have a 3-wire feeder. Ground/neutral is the same bus on the subpanel currently. Do we need grounding rods? Bonded ground & neutral?
Subpanel is probably 200 feet away, separate building (barn), no other metallic items connecting it to main building.
Other results from here/around the web are confusing me.
Edit: It is a 3-wire feeder with a bare stranded neutral. There is no ground, but we plan to place a grounding rod. I know, or think I know, that not to bond if it was a 4-wire feeder. We will measure voltage when we get a chance, sorry.
