Building a 750 sq foot detached garage and looking for some guidance and confirmation of research for the subpanel. Home service is 200amps. I want the detached garage to be 100 amp subpanel. The run is about 110' in total; 30' under the house in crawl space followed by 75' of 2" conduit buried 2' down. There a few bends approximately 300 degrees. The crawl space gets very narrow (belly crawling) I would like to use UF aluminium #2-2-4-6. Transition to a junction box using insulated splice ($13) a pop. Would like to use individual aluminum wire #2-2-4 with #6 stranded copper for the conduit section. I have unbounded the neutral and ground bars on the Subpanel, which was a main 100 amp 20 space panel. Have a ufer ground or rebar stick from my foundation to attach #6 copper to. My understanding is to tie 3 knots with the rope with an good amount of electrical tape and lube. I pull while a friend pushes. Is no-Ox on connections. Questions would be: does that all sound right? Does any of it sound crazy? Is the wire size appropriate? Anything that I am not thinking of? Thank you in advance for your input and time. Scott

I have a 14/2 line coming off my service panel in the basement which serves 3 pull chain incandescent bulbs and a 5 outlets in the basement I would like to put up 4 shop lights controlled by a switch. I am thinking of tapping off this line before the first light and going to a new switch followed by the wiring for the 4 shop lights. does this seem reasonable and/or appropriate? Is there a better way of doing this?
