Nut neighbor wants to run 400' of 3/4 conduit for a 120v outlet to plug in a very occasional skil saw or battery charger on a campsite.

Looks like 12 ga gives him 106 volts. Maybe a 15 watt porch light also. Does'nt want to pay for 10 ga. Would that be viable?

I suppose we must assume he would be also using a 50' cheap cord at the end of that 400 foot run.

Its a straight easy run, so I suppose the next guy could easily replace that wire.
