What size of conduit you use for 6 AWG wire?

For 6 AWG wire, you typically use a conduit size of 3/4 inch for one or two conductors. However, if you're using multiple conductors or have specific installation requirements, you may need to refer to the National Electrical Code (NEC) or local codes to determine the appropriate conduit size based on fill capacity. Always ensure to follow guidelines to maintain safety and compliance.
