What gauge extension cord for 30 amps?

30 Amp RV Extension Cord Gauge

For the 3,600 watts that a 30-amp cord can handle, you’ll want a 10 AWG extension cord.

What AWG is an extension cord?

Recommended wire gauge for extension cords

A cord measuring 14 AWG is the thinnest we recommend—and at lengths of only 25 feet or shorter—and the much thicker 10 AWG is likely the thickest gauge you’ll find in an extension cord.

Which is stronger 10 or 12 gauge extension cord?

Common household extension cords are available in 16 gauge (smallest), 14 gauge, 12 gauge, and 10 gauge (biggest). The lower the number, the bigger the gauge and the greater the amperage and wattage is.

Which is better 10 or 12 gauge extension cord?

Most devices will do fine with 12 gauge extension cords. Power hungry devices such as lawnmowers, heavy machines, require a lower gauge such as 10AWG. Keep in mind, the lower the gauge means the thicker the cord.

How big is 12 gauge wire?

12-Gauge Wire Dimensions/Thickness

Typically, a 12-gauge wire measures about 2.05 mm (0.08 inches) in diameter and has a cross-sectional area of around 3.31 mm2 (0.005 inches2). Note, though, that these dimensions are for solid AWG copper wires.

How do I know if my wire is 12 or 14-gauge?

How do you tell if your old wiring is 12-gauge or 14-gauge? Here’s a simple visual. Twelve gauge is about the thickness of a nickel, and 14-gauge is about the thickness of a dime. Also, look at the breaker for the circuit in question to see if it’s a 15-amp or a 20-amp breaker.

Is it OK to use 12 gauge wire on a 15 amp circuit?

However, 12-gauge wire is acceptable on both 15- and 20-amp circuits, so some electricians use it exclusively when wiring a house. This avoids the potential for mixing wire gauges in future repairs or additions, which is prohibited by the National Electric Code because it’s a fire hazard.

Is all 12 gauge wire yellow?

These can be house wiring colors identified as follows: 14-gauge conductors: White. 12-gauge conductors: Yellow. 10-gauge conductors: Orange.

How many outlets can you run on 12 to wire?

12-gauge wire can be used for both 15 and 20-amp circuits. A 20-amp circuit wired with 12-gauge wire can power up to 10 outlets. Outlets wired with 12-gauge wire on a 20-amp circuit can power most large appliances and power tools.

How far can you run 12-gauge wire without a voltage drop?

NEC (in the US) recommends no more than 3% voltage drop. For 12-gauge wire, operated at 20 amps, that would 51 feet.
