A 12AWG has less resistance than a 14AWG one which means less energy is wasted, and an eco-friendly circuit is created. This is due to a limit of 8.4 receptacles on a 14AWG circuit and a 10 receptacle limit on a 12 AWG circuit. Moreover, there has been a recent shift in demand from 14AWG to a 12AWG wire in residential projects. Most electricians prefer a combination of 12AWG and 14AWG in light fixtures and lighting circuits. It is rated for 20A and 25A at 60 degrees Celcius and 75 degrees celsius. For a visual, it has roughly the same thickness as a dime. 14 GaugeĪ 14 AWG wire is 0.0641 inches in diameter and is commonly found in lighting circuits due to its high flexibility and very thin size. It is also commonly found in refrigerators in 12-2 Romex form. Even though they might cost you more than a 14AWG size, they’re better. Apart from this, it can also be used in an air conditioner of 120V.įor outlets and lights, it’s the best option on a 15A or 20A circuit. This type can be found in kitchen and bathroom projects. While in aluminum 12AWG, only an ampacity of 15A is supported at any given temperature rating. At 90 degrees Celsius, it’s rated at 30A. It is rated at an ampacity of 20A at 60 degrees and 25A at 75 degrees. 12 GaugeĪ 12 AWG has a size of 0.0808 inches in diameter. It redirects any extra current to the ground in case of fluctuations. This process is connected to a grounding rod. This wire is bare copper in non-insulated form and can also be used for grounding and bonding purposes. It can also be found in 240V window air conditioners. Some common uses of a 10 AWG wire are in the electrical clothes dryer and electric water heaters rated 30A. The ampacity remains a fixed 25 A in the aluminum form at 60 degrees and 75 degrees Celcius. While at 90 degrees Celsius, the ampacity is 40 A. In copper form, the ampacity at 60 degrees celsius is 30 A and 35 A at 75 degrees celsius. It is why this product also goes by “building wire.” 10 Gaugeġ0 AWG is sized at approximately 0.102 inches in diameter. The nylon jacket protects against damage and shock and prevents the metal conductor from receiving any abrasion.Ī common use is carrying current to and from indoor light switches and appliances in homes and offices. This size is generally used for indoor projects. It is usually covered in a nylon sheath, Thermoplastic high heat resistant nylon (THHN). This type has several names and is known as: The ampacity is 30 A at 60 degrees in the aluminum form and 40A at 75 degrees. While at 90 degrees celsius, the ampacity is approximately 55 A. The copper conductor form is rated 40A at 60 degrees Celcius and 50 A at 75 degrees Celcius. The 8 AWG is sized at 0.129 inches in diameter. It can also be used in heat pumps and wiring of on-demand electrical water heaters. It is generally used in electrical cooking ranges and cooktops. While in aluminum types, the amp rating is 40 A and 50 A for 60 and 75 degrees Celsius. While at 75 degrees and 90 degrees, it is rated at 65 A and 75 A. It is rated for 55A at a temperature rating of 60 degrees. The 6 AWG size is approximately 0.1620 inches in diameter. If you need a 2 gauge wire, here’s our recommendation. Celsius refers to the temperature rating of the conductors. This cable is rated 75 A at 60 degrees and 90 A in the aluminum form at 75 degrees. Its diameter is approximately 0.2576.” This size is ideal for installing circuits where high flame retardation is required.Ī 2 gauge copper insulated wire can carry the rated amperage is 95A at 60degree. 2 gaugeĪ 2 AWG copper wire is commonly used for Central electrical heating systems. Let’s look at the most common options used in the industry and what they are used for. Fining out ampacities is no longer hard for your power cable! You’ll easily see the values and load the different options can handle, including ambient temperatures. Here is the THHN wire size chart you need. You no longer need calculators, resources, or tables scattered around the internet. The products which withstood our standard checklist are presented below. We have measured the output based on two factors i.e. You can trust us as we have worked closely with industry experts to test out different gauge wires.
