Follow along as I explain how I electrically wired my teardrop trailer. With a 30A converter and separate 110 volt line I have more than enough power for my rig.

College Final Year Project.
Year of Recording: 2010
There are three 100W bulbs in the video, and the setting in the breaker is such that only one bulb can be operated. If more than one bulb is operated then the breaker operates. The breaker is touch operated, the touch switch has been designed entirely for the breaker, the breaker can also be controlled remotely. A 433MHz RC module was used for the purpose, the video shows the demonstration of the remote control while switching on the bulbs.
The main project consisted of four parts:
1. Micro-controller and power supply board.
2. Remote controlled touch enabled Circuit Breaker.
3. Process Control Demonstration
4. Inverter Circuit
