Room Addition Home Electrical Wiring

Sub-Panel Wiring Electrical Wiring for a Room Addition
Background: Jim, a Homeowner from Utica, NY USA
[ad#block]Question: What sort of cable is used for an interior run to a sub-panel and are there protection/mounting requirements? Here’s the details:

We are building an addition (new room over the garage). We only have 6 slots left in our panel so I was thinking it might be good to install a sub-panel. The obvious route would be from the basement, up through an interior wall one floor to the attic, and then across the attic and into the back wall of the addition, about 75 feet total. One feed to a sub seems easier than 5 or 6 runs of Romex (plus 6 runs completely fills the existing panel). There will be 2 20A wall circuits, a circuit for overhead lights, a 208/230 for a heat pump and a 20A circuit for a supplemental/backup resistive baseboard heater (120 or 240). I was thinking a 60 to 100A sub should be sufficient.

Thanks for your advice and comments.

Additional Comments: This is a very nice site. Although I’m an electrical engineer, I don’t know that much about wiring and codes (I do semiconductor circuit design).
