High temperatures can cause the wire to lose conductivity, while low temperatures can cause the wire to become brittle. Higher altitudes also affect a wire's current-carrying capacity.Temperature
The temperature rating of a wire is the maximum temperature at which the wire can operate without being damaged. If the temperature exceeds this rating, the wire will become damaged and may fail. When derating a wire, it is important to consider the highest expected operating temperature, including any hot spots or areas with poor ventilation.Ambient Temperature
The ambient temperature is the temperature of the environment in which the wire is installed. High ambient temperatures can cause the wire to overheat, while low ambient temperatures can cause the wire to become brittle. It is important to consider the expected ambient temperature when calculating the derating for a wire.Altitude
Higher altitudes can cause wires to overheat because the air at higher altitudes is thinner, which reduces the amount of heat dissipation. When calculating the derating for a wire, it is important to consider the altitude at which the wire will be operating.Conductor Material
The material used to make the conductor can also affect the wire's current-carrying capacity. Copper conductors have a higher current-carrying capacity than aluminum conductors, but copper conductors are more expensive than aluminum conductors.How to Use Derate Wire Calculator
Derating a wire involves applying a reduction factor to the wire's current-carrying capacity. The reduction factor is determined using the environmental and application factors discussed above. To use the derate wire calculator, follow these steps:Step 1: Choose the Wire

The perfect cable size doesn't allow excessive voltage drops or system loss that hampers its efficiency. Derate wire calculators are an excellent tool to properly size conductors making electrical work more accurate and secure.
A derate wire calculator is a web-based tool or software that helps you calculate safe amperage for wires concerning different types of conduit materials, ambient temperatures, and wire insulations. Simplify your work by using a derate wire calculator that handles tedious calculations and ensures systems run optimally with maximum capability. It guides users as to how to achieve their required capacity without compromising safety or, more importantly risking personnel injury.
The National Electrical Code (NEC) also has specifications for applying correction factors when the temperature exceeding 20° C or about 68°F. When cables get hot functioning inside walls, it causes damage to the insulation system. As such, larger wires are preferred in such circumstances, at least two sizes up from what the wire table recommends. A wire rated for 15 amps installed inside a wall with a temperature of over 86°F would need to increase to a 20 or 25-amp conductor.
In addition to NEC guidelines, the derate wire calculators consider the tolerances defined by UL and CSA. Even though they don't replace NEC standards completely, UL and CSA add another degree of security to help you make wise choices. These three standards are convenient benchmarks for the electrical conductors used throughout building wiring systems.
The Derating factor depends on the following parameters:
- The ambient temperature of the location
- The number of conductors that will be installed inside the piping or conduit
- The size of the wire
- Type of insulation and material of the conduit used
Most electricians and electrical engineers would never short-cut to this degree. They usually use a derate wire calculator to maintain assurances of safety. When determining the needed response curve with reliability, you have to appreciate the message the calculator tools offer. The wire calculator provides guidance for long-term cable performance and the safety of those who use it.
Derate wire calculators are accessible online and free of charge, making it easier to calculate the correct wire size regardless of location. That said, there is no verified way to check the outcome of results provided by these online calculators. As such, they should not be taken as an authoritative source of information but only as a general indication. A professional electrician or engineer should always be consulted with to verify the suggested calculations.
Another important thing to note is that a derate wire calculator should be an aid, not a replacement of your calculations. Doing so implies taking the necessary details into account, such as the maximum and minimum temperatures within the wires, conduit fill volumes, continuous or undulated load amperage, and emergency overload currents. These calculations ensure that any wires you choose have sufficient space to dissipate heat and reduce unnecessary resistance that can degrade its performance.
Closing Message:
Remember, when selecting conductors, safety should be your first priority. Proper sizing will ensure you choose the right wires for your application, considering high functionalities and performance from your system. If ever in doubt, consult a professional electrician or engineer to guide you through Derating factors, minimum and maximum temperature parameters and other specifications based on your needs.
Use the power of derate wire calculators to confirm your calculations with a broad perspective, but never underestimate the expertise of professionals in this field. Finally, note that every selection has an impact on your system for an extended period, so taking time and effort to choose the right wire size over shortcuts is always worth it.
