# How do I know what wattage my extension cord is?

Typically, you can find a cord’s gauge rating printed on the cord jacket. If you’re replacing an old cord, look for the AWG number printed on the jacket, and select a new cord with the same gauge. To determine the cord’s capacity, consider the cord length along with the wire gauge.

As the cord gets longer, the current carrying capacity of the cord gets lower. For example, a 16 gauge extension cord less than 50 feet in length can power a 1625 watt (W) appliance. A 16 gauge cord that is longer than 50 feet in length can only power an appliance up to 1250W.

how many watts can a 14 gauge extension cord handle? 1800 watts

Simply so, how many watts can a 18 gauge extension cord handle?

#16 7 Amps 840 Watts
#14 12 Amps 1,440 Watts

How many watts can a 13 amp extension cord handle?

Buckingham Fire and Rescue Service recommends that extension leads and sockets should never have more than 3,000 watts of energy or 13 amps plugged into them. Some extension cords can not even safely handle 13 amps – these should have the maximum amps permitted printed on their cover.

### Does the length of an extension cord affect the power?

There are two factors: cord length and thickness. The thicker the copper wire, the more electricity it can carry. However, because transmitted power diminishes over distance, longer extension cords require heavier wire to deliver the full current rating required by an appliance.

### Can 12 gauge wire handle 30 amps?

A 30-amp breaker does not operate safely with a 12-gauge wire. The minimum wire size that is allowable for use with a 30-amp breaker is 10 gauge. A smaller gauge of wire indicates a larger diameter and the ability to carry more current safely. Twelve-gauge wire is acceptable with 20-amp or smaller circuit breakers.

1,800 watts

### How long can a 240v extension lead be?

Re: How long can an extension cord be? For a 10amp lead the “proper” answer is about 30 metres will be the limit for that 2200W jack hammer. In practice though you’d get away with double that as long as the mains voltage at the power point is at or above 240V.

### What is considered a heavy duty extension cord?

Heavy-duty extension cords are suitable for drawing 10 to 15 amps of power. These are always grounded extension cords that include a third wire and plug prong for grounding and have plugs with three slots for accepting grounded appliance cords.

### How many amps is 1000 watts?

Watts is watts = Amps mutiplied by Volts. 1000 Watts at 240 volts indicates an energy burn of 4.17 amps. 1000 watts at 12 volts indicates an energy burn of 83 amps.

### What is a 10 gauge extension cord?

Heavy-duty 10 gauge extension cords When you’re going to be running an outdoor cable that needs the highest amperage possible, you need one of our ten gauge cables. Each cable handles up to 30 amps, which means that you can use it to power up to two 15-amp power tools or appliances.

100 feet

### Does the length of an extension cord matter?

Extension cord length is an incredibly important factor. The longer the extension cord is, the more resistance. Extension cords come in various lengths, from a few feet to 100 feet. Although copper wire is a very good conductor, it does have an amount of resistance that generates heat.

### How many amps can 6 gauge wire handle?

### What is the best gauge for extension cords?

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.
