Sub-Panel Wiring Electrical Wiring for a Room Addition
Background: Jim, a Homeowner from Utica, NY USA
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).
Thanks for your electrical question Jim.

The Safest Way to Test Electrical Devices and Identify Electric Wires!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
The Quickest Way to Check for Faulty Electrical Wiring!The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.
Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..
The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
