As soon as you reach the town of Temperance, you’ll notice that all of the houses are not powered.
To power them, you need to connect the wires between houses and the generator.
Here’s how you can connect the electrical cables in Temperance in Raft.
You’ll notice that the power supplies all require an electrical cable connection.
Look for electrical cables first
You will need to find towers with a speaker on it. They will have 2 electrical cables each (image below).
Gather as many as you can from the towers around the island. There’s most likely more than enough electrical cables available.
From the main settlement, you can go north, east or west and you’ll find about 2 – 3 towers with electrical cables in each direction.
Just get as many as you can. The goal is to power all of the relevant houses until you reach the main building in the middle, which is the biggest dome.
Connect all of the electrical cables
After getting electrical cables, you can start connecting them between houses. There’s a big generator near the electrical tower in the settlement.
You need to start connecting from the generator to the nearest power supply.
Do the same for the rest as shown in the images below. You will find items to take in each building, especially vending machine coins.
You’ll eventually reach the biggest dome in the area and there are two floors inside.
There’s probably a blowtorch inside which is needed for a future puzzle.
You will also find vending machines in the biggest dome and you can exchange the coins you found for items.
