Any electricians?

[akunochi]

So I would like some input.

I need to run power to my shed and am looming at running a 40A remote subpanel. However the distance of teh run is ~150-200 feet depending on the path I take and wire prices are killing me. All wire will be placed in conduit and ran 18" underground.

After speaking to my grandpa who was an electrician for 35 years (But just confuses me) I know that 8/3 UFB wire or thhn wire can be used if it is copper. Problem this is almost 1k$$$

What about AL wire? I am assuming i would just need to run 6 AWG?

Also If I use THHN individual runner can I run just the 2 hot legs and neutral from the main panel and then run the ground to its own grounding rod at the shed side? This would save me about 200 feet of copper wiring.

Suggestions?

You don't need UFB wire If you run it in conduit. Wire Size Calculator

You have to check local codes about that ground, I think they require you to run it back to the main panel, not to say that won't work, it will.
