Electrician on board ?
Going to run a subpanel from my house toa new garage for my truck hobby workshop.
Pulling permit myself. 1st thing Im a little stuck on. Original thought was .... 240 - 50A. 6/3 NMB wire for 75ft through crawlspace. Then 2224 mhf wire in conduit to subpanel underground with schedule 40 UL 175ft away. Spliced with port multitap connector. But - I cant quite work out if 6/3 combination with 2224 is ok over this distance - seems ok on some voltage drop calcs to remain under 3% and not ok barely on others. Big step up in $$ 2x to 4/3. Can you use 2224 all the way ? or some other aluminum cable like SER of higher amperage/capacity. I dont see many people do that in threads though. thx

Re: Electrician on board ?
Perhaps a real electrician will come in but using the 6/3 at the beginning cuts your amp load carry to 60 right off while the 2224 is 90. Not to mention the junction is another place for a failure later.
Not sure on running the 2224 through your crawl space but I don’t think that’s recommended. Wired my shop from my outside house panel with a 60 amp breaker and similar wire for about 140 feet to the shop panel.
