How To Convert House Wiring to 12 Volt

When it comes to talk about electrical wiring in the house, most homeowners would say it’s something that they can get someone else to do. They would rather hire someone who’s a professional to do the work and that’s understandable. But, in reality, it’s really very easy to learn and do it yourself, if you’re one who has the time to do such household chores.

Converting house wiring to 12 volt is one such activity. If you are able to learn this simple task, you will be able to do simple conversions yourself in no time. If you would want to learn how to do this, read the following:

1. First, prepare the following:

  • a 12-volt transformer
  • a screwdriver
  • a digital voltage tester
  • wire nuts

2. The next thing to do is to find out if what you need is an AC or a DC 12-volt transformer. This is important so that you will know which between the two you would need to get your appliance to work. Doing so also lets you test the line correctly after wiring it.

3. Once you’ve determined what kind of 12-volt transformer you will be needing, you will have to look for the two thin wires that you will find on the transformer. These wires will be used to connect the transformer to the appliance or whatever it is that you are powering. Also, locate the two terminal screws in the transformer’s body. These two screws will be where you will be making circuit connections.

4. Some transformers may tell you what should be connected to each terminal and some, unfortunately, don’t. If this is the case, simply just connect the black house wire to one terminal and the white house wire to another. If you’re lucky and the transformer you laid your hands on have wiring preferences, then make sure that you have properly connected them so that it works fine. It is important to remember that all wires have to be secure and fixed and in their correct places before turning the breaker on.

5. Before turning the breaker on, attach wire nuts on both of the transformer’s wires. Once they are securely in place, that’s when you can turn the circuit on. After this, you can remove the nuts, at the same time ensuring that both wires don’t touch. You can already test the voltage that’s supplied by the transformer. Depending on the transformer, the tester should either display 12 volts AC or 12 volts DC. Just make sure that your digital voltage tester is set to read within that voltage range.

6. You can already turn the breaker off and then connect the transformer to the appliance that you need it for. Once all connections are in place, that’s when you can turn the breaker back on.

Converting your household wiring to 12 volts helps promote lower energy use. This is a particularly attractive concept for green-minded individuals and families, and will pave the way for a future in which households can use renewable energy sources like solar power to service their electrical needs.
