Limit on length is when used as the service entrance conductors. This limit is for all wiring methods presuming they are allowed to be used for service conductors, a few are not, NM cable would be one of them. NM however could be used for your particular garage feeder if it remains indoors the entire length. I'm guessing you maybe want an SE type cable because it should cost less if it has aluminum conductors, if copper is what you want either is fine.Making sure I can use SER cable from the house panel through the drop ceiling to the subpanel in garage. If I remember there isn't a limit inside the house for ser but wasn't sure. Thank you.
isn't that length limitation on USER cable?Limit on length is when used as the service entrance conductors.
