How do wiring

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.

Hot Wire Hot wire is used as the initial power feed to a circuit. Neutral Wire Once hot wire has initialized the beginning of a circuit, there must be another wire to complete the circuit.

The amount of current which can effectively flow through the electrical cable will be determined by a combination of factors:. The effect of resistance to current flow is the heating of the conductor and the surrounding insulation layers. Over-heating has the potential to cause failure of the insulation material resulting in current short circuiting, electric shock, or fire. Return to FAQs.

How do electrical cables work? Other questions What is inductance? Have the proper tools. Familiarize yourself with the different wires. Make sure you know which colored wire goes where and their purpose to avoid electrical shock and to safely wire your home.

Have more wire than you need. Make sure it stretches at least three inches outside of the electrical box. Patch drywall with big plates. Did you make the hole in the drywall too big?

Fix it with an oversized electrical plate. Pay for quality. Check the voltage before you touch wires and circuits. Do your research. Watch YouTube video tutorials. Electrical wiring mistakes to avoid. Remember the three-inch minimum on wire length. IF you do, add six-inch extensions. Never leave sheathing unprotected between frames, as in a ceiling installation.

Avoid loose switches or loosely connected outlets. Never install a three-slot receptacle without a ground wire. Instead, add a wall extension. Common household electrical problems.
