To introduce my situation, I'd like to preface by saying I built a 12x20 cabin on some family owned land for me. When trying to get electricity out here, the electric company said either A. They would have to set a new pole by the dirt road (100 ft. away), which would cost 1800$, or B. I could do underground burial to a pole in an opposite direction (behind me) that is about 160-180ish ft. away. They said if I go with option B, all they'd step in to do is put a meter on that pole, I'd be responsible for everything else.
Given those options, I'm under the impression option B with underground burial is the money saver route for sure. I can't imagine them setting a new pole 100 ft. away for 1800$ (plus w/e other costs) is going to be cheaper.
Now to fill you guys in on electrical expectations/usage. My demands will be very low. I won't list every single appliance, but in summary I'll most often be using a computer, 2 monitors, digital piano, speakers, microwave, hotplate, 2 LED bulbs, 6000 BTU AC in summer etc. (Usually, not all of this stuff will be plugged in at one time), and even if it was, I'm going to say this will only draw 2500-3000W combined. There is no 240V outlets in this cabin, and no demanding appliances like washers, dryers, electric stove tops, water heaters, shop tools, etc.
With the backstory and power expectations/draws out of the way, I'd to know what wire I should be on the lookout for? I'm a total noob, but was recommended by someone else that Aluminum 2-2-2-4 MHF wire is what I should get. I was using the Southwire's voltage drop calculator and assuming I input everything correctly, this is what I got "Voltage drop will be limited to 2.64% or less with a 2 AWG aluminum conductor delivering a total of 30 amps on a 120 volt single phase system for a distance of 180 feet"
(As stated before it's unlikely I'll ever draw 30 amps, but I put it in the calculator just to see) I put in 40 amps just for the hell of it, and it said voltage drop would be 3.52% which to my understanding is still healthy?? I was reading NEC recommends 3-5% ? ? ?
I'll be more than happy to provide any other requested information I might have forgotten that would help you guys assess and determine my needs.
