How to install water heater at home.

This page shows you how I install a hot shower at my condominium. However, you need to have basic knowledge about electronics and you will be fine. First step: You need to cut off the circuit breaker before doing this works. Second step: Find the right wire color and meaning of the color. As you can see in the above picture, the ground wire always green in color, and the hot wire is black. Unlike DC current load AC current use black color as a hot wire but DC current use black as a ground. Third step: Check resistance between neutral and ground, it should be 0 ohms or no more than 1 ohms. The resistance above 1 ohm means that the ground wire has a problem and elb, elcb may not work. Last step: Connect three wires to a hot shower and everything will be finished. See the video below for the complete project.
