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.
Can an extension cord handle 1500 watts?
Extension cords usually can’t handle high current
Medium-sized space heaters draw around 1,500 watts and 12.5 or more amps. That is what most extension cords can barely handle. The rating for your extension cord could be anything between 10-15A. It’s like you’re walking on the edge of a cliff.
How many watts can extension cord?
Matching Extension Cord to Load
| Extension Cord Wire Gauges, Amperage Rating, and Wattage | ||
|---|---|---|
| #18 | 5 Amps | 600 Watts |
| #16 | 7 Amps | 840 Watts |
| #14 | 12 Amps | 1,440 Watts |
| #12 | 16 Amps | 1,920 Watts |
What happens if you overload an extension cord?
Extension cords can overheat and cause fires when used improperly. Overheating is usually caused by overloading or connecting appliances that consume more watts than the cord can handle. Damaged extension cords can also cause fires.
How many amps can you run through an extension cord?
16-Gauge Cords: Any 16-gauge cord between 0 and 100 feet long will adequately handle tool loads up to 10 amps. 14-Gauge Cords: Any 14-gauge cord between 0 and 50 feet long will adequately handle loads between 10 and 15 amps.
Which is better 12 or 16 gauge extension cord?
Within 50 feet of your outlet, use a 16-gauge light-duty cord for blowers. For a higher Amp or a greater distance from the outlet, go with a 14-gauge medium-duty cord. Look for a “W” on the jacket if the cord is rated for outdoor use.
How many watts can an outlet handle?
As a rule of thumb, it’s safest to stick to a maximum load of 1,500 watts per outlet or circuit.
How many watts can a 16 gauge 100 ft extension cord handle?
1250 Watts
This cord is UL listed for safety and rated at 10 AMP/125 Volts, 1250 Watts. 16 gauge, 2 copper conductors.
How many watts will a 10 gauge extension cord handle?
10-Gauge How many Amps & Watts Can it Handle? A 10-gauge aluminum extension cord has a rating of 30 amps, or 3600 watts, at an ambient temperature of 167°F or 35 at 194°F. On the other hand, a copper wire of the same AWG has a rating of 30 at 140°F, 35 at 167°F, and 40 at 194°F.
How many watts can a 10amp extension cord handle?
You can run up to 2300 Watts with the 10 Amp extension and 3000 Watts with the 13 Amp extension.
What are three warning signs of an overloaded electrical circuit?
Signs of Overloaded Circuits
- Dimming lights, especially if lights dim when you turn on appliances or more lights.
- Buzzing outlets or switches.
- Outlet or switch covers that are warm to the touch.
- Burning odors from outlets or switches.
- Scorched plugs or outlets.
Does the length of an extension cord affect the power?
Extension cord lengths determine the cord’s power capacity. Every extra foot of cord increases the electrical resistance. This decreases the power the cord can deliver to connected devices. For best results, use the shortest extension cord possible.
What should not be plugged into an extension cord?
Rule two: never plug high power capacity appliances, like space heaters, refrigerators, or microwave and toaster ovens into power strips or extension cords. These appliances have higher power capacity and need to be plugged into a wall outlet directly.
How many watts can a 15 amp extension cord handle?
1800 watts
Most breakers are at 15 amps supplying 120 volts, or approximately 1800 watts.
Do extension cords reduce power?
Long extension cords can cause significant drops in voltage to appliances. Anything that resists the flow of electricity causes voltage to drop.Whether an extension cord causes a noticeable or significant voltage drop depends on the length and gauge of the wire and the appliance plugged into it.
Is a 13 amp extension cord enough?
Look for cords that can handle 15 amps
We recommend skipping indoor/outdoor extension cords rated for 10 A or 13 A. Instead, get one rated for at least 15 A. (If the cord doesn’t list a maximum amperage, you should skip it entirely.)
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.
What is the longest extension cord you can buy?

What is the heaviest gauge extension cord?
10 gauge
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.
Is 1500 watts a lot for an outlet?
Know the amount of power you’re placing on an outlet or circuit. Some recommend each outlet or circuit should not exceed 1,500 watts. Major appliances (refrigerators, dryers, washers, stoves, air conditioners, etc.) should be plugged directly into their own wall outlet since they are heavy power users.
How many watts can a 240 volt outlet handle?
How Many Watts Can A 240V Outlet Handle? A 240v outlet can handle 3,600 watts on a 15A circuit and 4,800 watts on a 20A circuit. With the 80 percent rule, you have 2,880 watts for the 15A circuit and 3,840 watts for the 20A circuit.
