This is why it is best to use this default chart to determine the capacity of the wire sizes listed belowĬalculations for Wire Load Capacity are determined by using an 80% Load Factor. There are also instances where more than one type of wire is used on a circuit. Specific conductor insulation types are determined based on installation environmental factors such as free-air, dry or damp locations.Īlthough the preceding table is true and accurate, many times the wire type is not known. These specifications are determined after any correction factors for ambient temperature and number of conductors have been applied. Unless otherwise specifically permitted in the electrical code, the overcurrent protection for conductor types should not exceed the following:ġ5 amps for #14 AWG, 20 amps for #12 AWG and 30 amps for #10 AWGġ5 amps for #12 AWG and 25 amps for #10 AWG Using the properly sized wire will ensure safe circuit performance. This rating limits the current flow in amperage thereby preventing the home-electrical-wire from overheating and causing a fire. The insulated wiring conductors inside Type NM Cable are rated for temperature. Protection is provided by Safety Plates, as shown in the table below. To protect wiring which becomes vulnerable to damage which could occurĭuring the installation of sheet rock or other wall coverings. Maintains structural integrity for the home. The installation of the Type NM home electrical wire is accomplishedīy drilling holes using approved methods which protects the wire and Originates back at the Main Service Panel.
