I'm dealing with some crazy voltage swings in my house's electrical so I am hoping PM has some insight.
The house is a '56 vintage with high-leg delta service, although the 208v is unused. When the A/C is off X/Z voltage is ~245v split evenly. When the A/C turns on there is a shift where one half of the split drops to ~108v, and the other increases to ~136v. This voltage swing is playing hell with our lights/fans/etc. What's even more odd is that the A/C unit is on It's own panel that is directly fed from the meter base, ergo it's draw shouldn't affect panel voltages.
The panel is probably original (pic attached) and obviously less than ideal, but I've only recently inherited this problem so it's all new to me.
Does anyone have some insight to this before I call an electrician?
Thanks, Cole
