An existing home has a 10/3 with ground to an oven unit, no cooktop, that keeps burning out. A voltage check indicates 220 across the hot leads, 110 volts hot to ground, but 70 volts hot to neutral. Would this indicate that a staple has possibly penetrated a neutral and causing high resistance. The voltage is correct at the overcurrent device, but falls at the first junction box. Looking for ideas, thank you.

Re: unbalanced voltage

Sounds like extremely high resistance in the neutral circuit between the panel and oven. Look at the splices. If splices are OK then yes a staple could have penetrated.
