Answer

3. 2/0 AWG through 4/0 AWG Explanation 1. Identify NEC Code Requirements According to the National Electrical Code (NEC), copper conductors must be supported twice as often as aluminum conductors starting from a specific size. 2. Determine Size Range for Support Frequency Copper conductors require more frequent support than aluminum starting at 4/0 AWG. This is based on NEC guidelines for vertical raceways.
