![]() Hence, always check an appliance’s gauge wire amp requirements before using it. The maximum safe capacity each wire gauge can carry is measured in ampacity. The different sizes indicate how much current can safely pass through the wire without burning it with electrical heat. The wire diameter increases as the wire gauge number decrease. Numerous wire types and sizes are available made by the American Wire Gauge (AWG).Įach wire type and size are intended for specific applications. Hence, it is critical to understand the conductor material and insulation rating. For example, a 6-gauge copper circuit rated at 90☌ has a capacity of 75 amps, whereas a 6-gauge aluminum conductor rated at 60☌ only has a capacity of 40 amps. It means that an aluminum wire must be larger than the same size of a copper wire to handle the same load. Depending on how your conductor is constructed, you may have more scope in determining whether a 10-gauge wire can handle 40 amps.Īluminum wire has less ampacity than copper wire. Aluminum is more resistant than copper, which is why it is becoming more popular. The conductor material is a critical factor in energy load.Ĭopper cables were commonly used in electrical work, but aluminum has taken its place as the price of copper has risen. So, if you’re going to run them 100 feet, you should consider using 8-gauge wire instead. Moreover, a 10 AWG copper wire is common for short 30 amp runs only. Also, people living in RVs frequently use 30 amp systems to power all vehicle appliances. It is used for household items in residential homes that require a 30 amp circuit, such as the window A/C units, dryer units, heaters, and stoves. Thus, using 10 gauge wire for anything more than thirty amps is dangerous.Ī 10-gauge wire has a sheathing of orange. Using 10-gauge wire for an extended period of time could be hazardous as the wire would overheat and burn through the insulation. Well, it is possible but for a short time only. However, this is not always the case, as people occasionally use applications that draw more than 30 amps. So, any appliances you use on it should not exceed 30 amps as it is the natural consensus, which is true for many residential properties. Understanding 10 Gauge Wire and Its AmperageĪs a rule of thumb, 10 gauge wire isn’t designed to carry 40 amps and is rated for 30 amps only.
