I’m in Illinois for the weekend helping my dad install a new electric range in his house. Previously the stove was gas. Ran a new 50 amp circuit from the GE panel to the range and hooked everything up. Nothing happens. I check the breaker and there is no voltage across the two terminals or to neutral. The breaker looks different than the other breakers in the box, but it appears to fit. The box is about 15 years old, does anyone know if GE has changed their box or breaker design in the last 15 years that would cause a new breaker to not work in an old box? I’m headed home early Monday and won’t be able to get to any store other than the big box due to the holiday.
