Hello Guys. First I would like to say thank you for all the help I’m getting in this forum. My question is that I have a 60 amp sub panel with a number 6 wire, it is connected from the main panel on a 60 amp breaker. And going into subpanel feeding both legs a neutral and a ground. If I want to change it to a 100 amp can I still use the number 6 wite that is currently there?
