Knockout On Main Breaker Panel


I am installing a new 200amp main breaker box, the old box has knockouts with up to 7 wires coming in through one knockout (with a connector). On the new box what is the max amount of wires that can come through a single knockout?

Thanks

You can not push conductors thru a knock out with out protecting the conductors. You will need some type of connector. The connector will determine how many conductors you can install. It will have the number such as 2 #12 and 2 #10 ect

Unless you have a surface mounted panel and several other conditions, you will need to use multiple knockouts for the cables. Check the cable size combinations on the package for the connectors to see how many cables are allowed in each connector.
