I want to start connecting electronics (micro controllers) to run/manage power outlets, but everyone always states to leave it alone unless you have experience. Well, how does one get started without becoming an electrician?
A few ideas came to mind, but I don't know if they are applicable:
- Start small. Wire a small bulb to 9V battery and a power switch.
- Medium. Wire a car battery to an RC car? I'm making it up to give the idea.
An electrician fixed a few light switches in the house and he was boasting that he's able to change power outlets and light switches without ever turning the power off to the house. He told me to follow these steps and I should be safe when replacing light switches while leaving the power on in the house:
- remove the plate
- find ground wire identified by a greenish/copper screw and unscrew it.
- connect that to the new light switch
- find neutral (white cable coming from a metal case that has other cables coming from it) and connect that to the new light switch
- finally, remove the Hot wire (could be black, but color may be anything - use a non-contact tester) and connect that to the new light switch.
Even thought he performed these steps in front of me, I've not attempted to do them myself. Any guidance, sample projects, books one safe ways to get experience would be appreciated.
