I am having a new heating system installed which is going to include a new AC system that was not present before. I am also buying a new range which requires 220v. I only have space in the breaker box for 1 220v-30amp breaker. When I run the wiring for the emergency disconnect for the AC compressor, can I also piggy back off of that wiring and continue to the plug for the range? If so, what guage and type of wire would you recommend?
