Code Question of the Daytextbook

    CQD 4/9/2021

    Good Day Code Fans,

    One the electricians on this project said that panelboards no longer are limited to 42 circuits. I told them it was a Code rule, but the manufacturer of our electrical panels shipped one that has 60 single pole breakers in it. Has this rule been changed?
