If you check the chart below, you will see that 12 AWG extension cord can handle **up to 18 amps (25-feet and 50-feet cord)**, up to 15 amps (100-feet cord), and up to 10 amps (150-cord).

## How many amps is a 12 3 extension cord?

50-ft 12/3 Heavy Duty Lighted SJTW Indoor / Outdoor Yellow Extension Cord by Watt’s Wire – 50′ 12-Gauge Grounded **15-Amp** Power-Cord (50 Foot 12-Awg Yellow)

## How many amps can a 50 foot 12 gauge extension cord handle?

For instance, for a length of 25 – 50 feet, a 14 gauge cord will be great for 14-15 Amps, whereas the 12 gauge will work for **16-20 Amps**.

## What does 12 AWG on an extension cord mean?

16 gauge=light duty. 14 gauge=medium duty. 12 gauge=heavy duty. 10 gauge=very heavy duty.

## 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.

## What does AWG mean on a cord?

**American Wire Gauge** (AWG) is the standard way to denote wire size in North America. In AWG, the larger the number, the smaller the wire diameter and thickness. The largest standard size is 0000 AWG, and 40 AWG is the smallest standard size.

## How many amps is a AWG?

## 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.

## Is it OK to mix 12 and 14 gauge wire?

**Certainly, but you shouldn’t exceed the current capacity of the smaller conductor**. In this case, the 14 gauge wire, which in the US at 120V is typically rated at 15 Amps. (12 AWG is rated at 20 Amps.)

## 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**.
