I've really spent a few hours searching and reading this site to find the answer to my specific situation and I'm sure it's here somewhere but I'm tired of searching.:happysad: Looking for some answers...
I purchased my place 15 years ago and back then it only had a double wide trailer and a 200 amp service. No problems.
Since then, I've built a water house which I fed with a 100 amp main.
Then, I built the shop. (with permission from my wife) with a 125 amp main.
Then a new 6000 square foot house with an extension of the 4 wire system at 200 amps from the 200 amp meter that has the bonded ground and neutral. This house is 190 feet away from the shop.
I moved the 200 amp meter base to the shop at the same time I built the house because it was on a broken down pole in the middle of the driveway.
Here I have a 200 amp meter with a ufer to the shop bonded to the neutral at the main panel A.
I have a water house with a 100 main on this panel. 4 wire, with a separate ground and neutral. Sub panel B, not bonded and is 130 feet from the main panel at the shop.
At the house location, Sub panel C, I have another ufer bonded to the gec from the main panel A.
During this last winter, I had a situation where I had 98 volts to ground on either phase but I had 124 VAC to neutral.
At this time, during the summer, I have 124 VAC to ground and neutral.
For the life of me, I can't seem to figure out why this would happen.
NEC states that I don't bond the neutral and ground at Sub panel C in this scenario with multiple buildings but I can't help but wonder, if I did, would this solve my problem?
Let the beatings begin!:slaphead:
Additionally, at the shop, Main panel A, I have a 7KW enphase solar system and that panel is not bonded.
Seriously, any info or feedback would be greatly appreciated.
Thank you,
Bruce
