First, I know this is my first post, so please be gentle. I've done some searching and have found a lot of posts about adding a panel for external buildings (garages, sheds, etc), but either my queries are wrong or I am just skipping over the ones I need. I realize this is a large job, likely best placed in the hands of a professional. That said, I'd still like to tackle it with proper guidance because I'm a relatively hands on person.
Cliff Notes Version:
200 AMP service panel in attached garage. Want to add 100AMP subpanel in basement, to provide service for finished basement and potentially add a hot tub in rear of house, outside the basement door. I currently only have 3 spots left open in my main panel.
Location: Delaware
About me: Homeowner, and have done some home electrical changes myself. (Re-wired switches to control a ceiling fan instead of 1/2 an outlet, installed the boxes necessary for those jobs, etc.) This will be my largest electrical task to date.
I originally thought about putting in a 50AMP subpanel using 6/3 wire, but figured if I'm going to go through the trouble of installing a panel I mind as well plan for the future just in case.
My research so far is pointing me in the direction of using 2-2-2-4 SER wire to provide a feed to the subpanel. Can someone confirm if this is the correct wire? The main panel will use 2 of the 3 available slots and will have a 100AMP breaker installed there, as well as a 100AMP breaker in the subpanel in the basement. I'm also aware that the I'll need a separate neutral bar and grounding bar in the subpanel.
The main questions I have surround how to get the (2-2-2-4) wire from the main panel to the basement. I've added a diagram (which is unfortunately small(er) than I'd like, but hopefully helps. The main panel is located in my attached garage, front left corner of the house. The subpanel can, at this point, be placed anywhere in the basement as I'm still in the process of framing.
I have a two floor home, with un-used space above the garage. I could go through the attic, and climb down, above the garage, and run the cable through the wall, across the attic, and down another wall to the basement. Alternatively, I was hoping to run the cable through conduit, either along the wall into the basement, or across the basement ceiling and down another wall. (Either works, really.)
I've tried my best to mark the attached diagram to where the main box is located, and the proposed ways to get the cable into the basement. Any and all advice is welcome. (Good or bad, I'm a big boy, I can take it.)
Some notes on the Diagram:
All Sub Locations are in the basement.
Sub A location will be in an unfinished area of the basement.
Sub B location will be in finished section of the basement. That section is an office, and the location of the panel would be in the closet of that office.
Sub C location is underneath the steps, inside a finished closet.
Thanks in advance for either helping, or taking the time to read this rather lengthy post. If I can answer any questions that will help you form a better opinion, please let me know!
