Running electrical to shed

I have a simple 12x12 shed on skids, to which I want to add electricity. I don't want a permanent, buried cable, as that means permits and my shed doesn't qualify. Here's what I was hoping to do:

I have about 70' from the breaker box to my crawl space door. I'd run a fresh line to an outlet in the crawlspace right next to that door.

From there, I have about 60' to the outside of the shed. I'd run an extension cord from the outlet in the crawlspace to a exterior grade inlet on the side of the shed.

From there, I'd have maybe 25' of cable to the furthest outlet.

How does that sound?

Okay, now let's step it up a level. I want lights and a window AC, along with a compressor or power tool (table saw, router, etc). I was thinking that I could do 240v to the shed, and split it into 2 circuits with a small breaker box in the shed. But can I do a 240v run like that? Or would it be better to do 2 separate 120v runs?

I'd suggest a 30 amp 120/240 receptacle at the house and a portable subpanel you could plug into it. You are going to spend a lot of extra money to avoid permits.

Your idea really isn't kosher from a code perspective.

I've done something similar for an ice fishing shanty on skids with a long extension cord to the dock, but we obviously didn't have AC, table saw or compressor to worry about. I think you'll spend a lot more buying heavy enough flexible cord to run those machines over 100' distance than you would to bury a circuit or small subpanel feeder out to the shed.

You could bury a feeder to a pedestal (4x6 treated post) right next to the shed, so the panel is on it's own "foundation", then run your short drop cords from outlets on the pedestal into the shed while it's in use. This would be very similar to an RV hookup.

Thanks for the input guys. I'll just run a couple of 20A circuits to a pair of exterior CGFI outlets on the side of the house, and make that work.

What does your local code call for as far as grounding rods go? You would not want a lightning strike running back to the house for example.
