Currently I have a 10/3 wire running from the breaker box having a 50amp breaker running underneath the house. I was told this was a hazard. I want to run a 6/3 inside wire under the house but inside conduit pipe. My question is, will I be safe in disconnecting wire by wire in the panel once I turn off the breaker in the panel. Also I was told the 12/3 wire leading to the dryer with a 30 Amp breaker was wrong. The city inspector OK'd it back in 1990. Was he wrong or do I need a 10/3 for this?

 

6-3 copper minimum for a 50 amp 120/240 circuit. 10-3 minimum for a 30 amp 120/240 circuit. It is best to use individual conductors, THHN/THWN, in conduit. 6-3 would be a real chore to pull through conduit.

 

Why do you want to run conduit for this? Also, how much power does your range draw?

 

You could take the 10/3 from the incorrect range circuit and use it for the dryer circuit.
