House Wiring Common Wire: All You Need to Know

Home wiring is an important aspect of the modern home. With the advances in technology, more and more devices rely on electricity for their operation. As a result, it is important that the wiring in your home is done properly to ensure that the safety and functionality of your home are not compromised. Common wire is one type of wiring used to connect electrical devices in your home.

Common wire, also known as Romex, is the most common type of wiring used in residential homes today. It is made up of insulated, color-coded plastic-sheathed cables that are available in various gauges, depending on the amount of current required. Common wire can be used for both 120-volt and 240-volt circuits and is relatively easy to install with basic knowledge and tools.

What is Common Wire Used For?

Common wire is used for nearly all applications in a residential setting. This includes outlets, light switches, and lighting fixtures. It is also used for dedicated circuit applications such as air conditioners, dishwashers, garbage disposals, and garage door openers. It is also used for many other dedicated circuits such as doorbell circuits and remote controls.

Common Wire Sizes

Common wire is available in several different sizes or gauges. The most commonly used sizes include 14-gauge, 12-gauge, 10-gauge, and 8-gauge. Generally speaking, the lower the gauge, the thicker the wire, which means the higher the current capacity of the wire. The following table provides a quick reference guide to common wire gauges:

Gauge	Current Capacity
14 Gauge	15 Amps
12 Gauge	20 Amps
10 Gauge	30 Amps
8 Gauge	40 Amps

Common Wire Installation

Installing common wire is relatively simple and straightforward. The first step is to run the wire from the power supply to the destination. This can be done through walls, ceilings, or floors, depending on the application. Once the wire is in place, it must be connected to the proper terminal using suitable connectors. Finally, the wiring should be tested for continuity and any necessary loads.

When installing common wire, it is important to follow all local codes and regulations. This will ensure that the wiring is installed safely and meets all safety standards. Additionally, it is important to exercise caution when working with electricity. Working with electricity can be potentially hazardous and should only be done by qualified electricians.

Conclusion

Common wire is a versatile and widely used type of wiring in residential homes. It is available in various gauges and is easy to install with basic knowledge and tools. When installing common wire, it is important to follow all local codes and regulations and to exercise caution when working with electricity.
