How do you attach power to home items like the TV and Jukebox? The plain wire won't connect.

You don't. As long as there is a Power Relay that is receiving power, any item within a certain radius of it will get power automatically.

I had to make power conduits and place them on the outside of the house. Then, run a wire from the generator to the power conduit. Power relays may work in a similar fashion, I just haven't used one yet. You need 1 copper to make 1 wire. To make a wire, enter workshop mode and move your cursor over the generator. Down at the bottom, youll see which button you need to press to make a wire. Then attach the wire to the conduit/power relay/other item that requires electricity. On xbox, the wire button is Y. On PS4 im guessing its triangle. Couldn't say what it is on PC but it will say on the bottom of the screen after you hover over an electrical piece that can be wired up.

Once the generator is hooked up to a power conduit (or a relay im guessing, based on what the first reply said) the electricity will radiate out in a radius of 1 or 2 walls depending on the type of piece it is. All you have to do then is build a light nearby that power conduit/relay and it will turn on.

If a light (or other type of electrical item) has only an electrical symbol under its name, it will turn on as long as its nearby a powered conduit. if the electrical symbol has a number next to it, you have to run a power line directly to that kind of piece.

For items with no number next to its power requirement, you can think of electricity as working wirelessly like your WiFi would.

Hope this helps!

That's not quite correct. This isn't broadcast power; this is an electrical grid. Household items like the Jukebox and house lighting require that the house has a power line from it connected to a generator. You accomplish this by attaching a connector to the outside wall of the house, and thereafter, the entire house provides power to items inside the house. HOWEVER, that connector has a "zone of influence", outside of which items in a large structure such as the Large Shack may not be getting fed electricity. The solution is to place a second connector at the other end of the building and run a power line from the first connector to the second. (That may involve placing intermediate connectors if the line is required to go around a corner.) The same applies if you get ambitious and decide to build higher than two floors; you'll need additional connected connectors ever couple of floors.

I dont think that's always the case, I stuck a pylon on the 3rd floor roof and it powered the ground floor lights too.
