50 amp stove line question
I'm in the middle of a kitchen remodel. Where the old kitchen had a cooktop we're installing a freestanding 30 " electric stove. We want to Use the existing wiring from the cooktop (50 amp - 4 wire ) to power the stove. The box is mounted about 24" off the floor where it will be behind the stove. The stove calls for electrical box mounted on wall between the floor and 8" off the floor. The wiring comes from the ceiling so I can't move the box down and running a new line back to the breaker box seems like too much work.
Can I tap the wires in the current box and install a new box at the floor? If so this would require joining 4each pairs #8 stranded wires. What size wire nuts for those? I was thinking maybe install a disconnect box where the current box is as this would make connecting these wire sizes easier.
