I have a hunting camp that has both electrical and dc lights as well as a few ac outlets. The AC system is all tied into a 10 guage extension cord going to generator 15 amp. Theres no breakers or anything so basically its a makeshift extension cord running through camp.

I want to split it into two lines both 120 15 amp. As if i use inverter gen it doesnt support 30 or 50 amp.

Id like to put two male plug boxes where gen goes and hardwire romex circuits from those. The thing is it will still have zero breaker protection. Any ideas?

One set of outlets would have a microwave tv dvd player and speaker bar

Other line would have a couple nox fans. Each line would have a few led lights.

I can get a two breaker panel for 21 bucks

Get a breaker panel, simple solution. Wire in an "inlet" on the outside to feed breaker panel, then wire in your circuits off panel, all fuse protected. Its actually a low cost deal.

Do the split at the breaker panel. As Brett said, dirt cheap, especially if panel is inside and its not outdoor rated. Get a common brand, ie Square D or GE Homeline series. (Home Depot etc)

Wire it to code, ie wire sized for breakers etc.

I like lighting separate, I use 14AWG and 15A breakers, outlets can be 15 or 20 depending on locations. 20's nice in kitchen or any outdoor outlets, use 20AWG or yellow Romex. Feed the panel from inlet with 10 AWG (orange wire) and lighting, white romex (14AWG)

As Brett, and Toyota said, Use a small breaker panel/load center.

We used THIS $30 one, a Square-D, both in our cabin and in the shop. Hard wire to it from the generator- I just wired a male plug on the other end that is plugged into the generator. The box is of course installed inside. Keep in mind when supplying only 120v to a load center, a jumper will need to be installed across the input lugs to energize the other side of the box/breakers.

From here, wire your cabin as would normally be done. We ground our generator, most have a ground lug on the front, this will keep the ground from "floating".

Your gen most likely has integral cb protection for its face panel outlets.
Note that if it has a duplex receptacle that is 15a both both, not each.
The beginning question comes down to what are you intending to power? Have you done a power audit?

How is it wired currently? In the cabin I mean? Romex in the walls or extension cords?

A small subpanel box and a couple of breakers should be under $40 (US). I just used a marine shore power connector on the outside wall to connect the 2000w generator with an extension cord. (The picture may look a bit odd as I am off the electric grid, but I have a fibre internet connection in the cabin.)
