Ac which wire is hot

So, with hot and neutral already being used to make a circuit, what role is left? The answer is safety of course! Ground wire acts as defense against unstable electrical currents. But when an electrical accident such as a short circuit occurs, the ground wire takes the unstable current away from your electrical system and sends it toward the ground.

Ground wire is easily identified by its green casing. But not all homes may have it. To tell if your home has ground wire, check your outlets.

If your outlets have three prongs, then your home has ground wire. If there are only two prongs, then ground wire may not be utilized. If the latter is the case, we recommend consulting with Roman Electric to help determine if your home can be retrofitted with new ground wire.

The black wire is always going to be the hot wire, holding electricity. The black wire will never be used for neutral or grounding purposes. A red wire is another wire considered hot.

Always proceed with caution. The bare wire, green or green with yellow tape wires are the grounding wires. Green grounding wires should always connect to only other green grounding wires. Grounding wires are used to protect people and appliances from shock, in the event, it contacts any conductive part of the frame. Treat it as it is a hot wire.
