So the main is in the garage?
That had me puzzled a bit also. I have 100 AMP subs that are the size of your main, so now I know the smaller panel is the sub, and "power center". How about a close up of that unit? It all looks very professional!
Of course the usual admonition by a member who is no longer with us would be near the top of the thread.... get a licensed electrician, woodworkers are not electricians. Well, some are some aren't, or at least some are qualified/skilled enough to do the work. The other difference is that you are not seeking advice, just showing your skills.
The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)
