This morning parts of home electrics were not working. Total novice but know how to check voltage at breaker box. I have top leg at 119 to 122, bottom leg fluctuates from 30ish to about 95 or so. No burn or heat markings or temps and voltage reads the same on both sides of each two main breakers. Oddly also wireless meter which is sealed but usually shows numbers is showing nothing? I checked each individual breaker and every other one on each side shows lower voltage. No reset switches in home have clicked off. Thinking it could be a bad connect outside either at site or at service line which is above ground at street and goes underground the 300 or so feet to meter on home. Thanks for any advice or direction. I tried calling service provider but the office is closed til tomorrow morning.
