Do Not Forget About the Electric Ground

"I'm glad I read about this electric ground!"

An electric ground is the normally green wire that is meant to protect electrocutions from occurring. This is a similar concept to wearing rubber soled shoes. Because of the poor conductivity of rubber, you are not able to complete the electrical circuit. Therefore, the electricity will go out of you rather than shocking you over and over. However, if you’re touching metal or some other type of good conductor in two different places, you are at an extreme risk of being shocked and possibly killed.

Obviously this is just a brief overview, and simply knowing this will not save your life. You need to be extremely careful at all times when you’re working with anything electrical. With that said, you won’t find a how to guide here. You cannot expect to learn how to wire a circuit to anything by reading a guide online. It’s really not that easy. Would you feel prepared to perform a surgery by reading an instruction manual? Hopefully you would not be so bold! Instead, you can just learn about different aspects here to feel more familiar with the terminology and concepts.

Typically, you’ll see different types of romex wire being used in residential applications. These are specially jacketed types that are usually referred to by their gauge or size. For example, common sizes are 14/2, 14/3, 12/2, 12/3, 10/2, 10/3, 8/2, and 8/3. They usually all come with a ground unless otherwise noted, though it can be confusing because sometimes the ground wire itself is not counted. For example, 14/2 with a ground has the same amount of wires as the 14/3. Confused yet? That’s why it should be left to the professionals. Typically, all have nm b following, such as “12/2 nm b”.

There are also ground rods, which are either made from copper or galvanized steel. They can come in 8’ to 10’ tall segments. They act as a way to check and test and hold electrical systems together. So you’ll see that a lot more goes into any type of wiring job, no matter what kind of load is at stake.
