# Do I need 12 or 14 gauge extension cord?

For 100 feet, the 14 gauge cord works for 11-13 Amps, while the 12 gauge cord is best suited for 14-15 amps. If your cord is 150 feet long, the 14 gauge is best suited for 1-7 Amps, whereas the 12 gauge will support 8-10 Amps. This shows that the extension cord’s length also plays a part in the power it helps safely.

## Which is better 12 or 16 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.

## What can a 14 gauge extension cord run?

A 14-gauge cord is for medium or frequent duty applications (lawnmowers, power drills, table saws, television sets, etc.). These cords are also great for things like power tools, electric chainsaws, leaf or snow blowers, etc. They can handle larger tools and equipment and heavier use.

Do I need 12 or 14 gauge extension cord? – Related Questions

## How many amps can a 14 gauge extension cord hold?

14 Gauge for 11-13 Amps. 12 Gauge for 14-15 Amps. 10 Gauge for 16-20 Amps.

## Can an extension cord be too strong?

The general rule is the more amperage, the better. For example, if you have a 30 Amp extension cord, it can handle two devices that require 14 amps each to work. You should never overload the power cord because it may lead to fires, and it is a huge safety risk.

## How much power can a 14 gauge wire handle?

Example: A 14 AWG copper wire can carry 3,520 watts at 220V. At a much smaller 12V voltage (batteries, for example), the same 14 AWG wire can handle only 192 watts of electrical power. In the wattage charts below, we calculated wattages at 12V, 24V, 110V, 120V, 220V, and 240V for all wires.

## Will 14 gauge extension cord run a camper?

The Camco RV/Standard Home Extension Cord – 15-Amp, 50-Foot, 14-Gauge is designed for you to be able to power your RV or your household appliances from distant power outlets.

## Can I use a 14 gauge extension cord for microwave?

We strongly recommend that an extension cord not be used with a microwave due to potential safety hazards under certain conditions. Your microwave should be plugged into its own properly grounded, dedicated electrical outlet to prevent the flickering of the lights, blowing of a fuse or tripping of a circuit breaker.

## What happens if I use the wrong gauge extension cord?

Using an extension cord with too small a gauge of wire for the current draw will cause the wire and cord to heat up! This can lead to melting of receptacles, damage to your electrical device (and could potentially cause an electrical fire).

## What kind of extension cord is safe for a heater?

Using an extension cord with high wattage appliances can start a fire. If you must use an extension cord, it must be marked 14 or #12 AWG, this tells the thickness or gauge of the wire in the cord.

20 amps

## 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.

## Can an extension cord gauge be too big?

The wire can never be too big, but it can be too small. Also, keep in mind that if you attach a multi-outlet device to an extension cord, allowing several tools to draw power at the same time, the current demand may exceed the amperage rating of the cord and create an unsafe condition.

## What should not be plugged into an extension cord?

They are NOT allowed to be used for high-power loads such as microwaves, coffee pots, refrigerators, toasters/toaster ovens, or space heaters. Doing so creates a serious fire hazard. Below is an example of a hard-wired power strip you may see in some rooms. These usually have 4-24 outlets.

## How do I choose an extension cord?

How to Pick the Best Extension Cord at the Hardware Store
1. Buy longer than you think you’ll need.
2. Thicker cords can carry more power.
3. Look for cords that can handle 15 amps.
4. Cords designed for cold weather are generally more flexible.
5. Skip indoor/outdoor cords with multi-outlet ends.
6. Different guidelines for indoor-only cords.

## How do I know if my extension cord is overloaded?

Extension Cord Safety
1. If any part of the extension cord is hot while in use, it is a warning sign that it may be overloaded. Check if the extension cord is properly rated for the products that are plugged into it.
2. Do not overload your extension cord by using it to power appliances beyond its capacity.

## What happens if you plug too many things into an extension cord?

Plugging in more appliances than the circuit can handle causes it to overheat and leads to damaged wiring. The heat combined with a damaged electrical system is dangerous because it significantly increases the risk of an electrical fire.
