There is, which makes me think of something. Another one of my customers which is in an industrial park farther west,
lost a primary leg to the xfmr. The Power co was troubleshooting it. During the day while I was waiting for them to fix the hit pole, I hunted down the trouble man who I met with, and he said a cut out down the line was open. Maybe what happened was when the low voltage line pulled off it snapped into the primary, which opened the cutout and also fried my breakers inside this other building... Interesting, I didnt put the two together
