How Do I Choose An Extension Cord?

Which is better 12 gauge or 14 gauge extension cord?

14-Gauge Cords: Any 14-gauge cord between 0 and 50 feet long will adequately handle loads between 10 and 15 amps.

12-Gauge Cords: If your tool load is between 10 and 15 amps and the length of the cord is 50 to 100 feet, you need a 12-gauge cord to safely power any tool.

This is a great extension cord for many purposes..

Can I plug my fridge into a surge protector?

We do not recommend connecting a refrigerator or freezer to a surge protector. The compressor is sensitive to temperature and current overloads, and will shut itself down with a surge. … A surge protector will override this system, and if there is a power surge, your refrigerator may not restart.

Do long extension cords lose 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.

How far can you run a 30 amp extension cord?

The actual answer is: “there is no maximum, as long as it is rated for 30 amps”. The question should be not how many feet, but how many cords. A 100 ft extension cord rated for 30 amps is not the same, at all, as two 50 foot 30 amp extension cords.

How do you size an extension cord?

Medium-Duty Extension CordsUses: televisions, computers, and other devices that draw up to 10 amps of power.Cord length up to 25 feet: use 16 AWG wire.Cord length up to 50 feet: use 14 AWG wire.Cord length up to 100 feet: use 12 AWG wire.

What gauge extension cord do I need for a refrigerator?

Extension cords with a lower gauge number—like 10 or 12 gauges—are considered heavy-duty cords because they have a higher capacity to deliver power. Since the 10-gauge cord is an extra heavy-duty extension, it makes the best choice for big power loads like a refrigerator.

What is the most heavy duty extension cord?

US Wire 65050 50-Foot Heavy Duty Extension Cord If you simply want one of the best extension cords on the market, the US Wire 65050 is a great choice. Not only does this heavy duty cord support up to 15 amps of current, each strand is individually double insulated 12 gauge wire.

What does 12/3 mean on an extension cord?

Typically, outdoor extension cords will have a number on the packaging or in the listing that looks like this: 12/3. The “12” represents the gauge wire rating (or wire diameter), and the “3” means it has three wires (or conductors) inside.

How far can you run 12 gauge wire on a 20 amp circuit?

The total circuit would be about 60 -70 feet in length. It would only be supplying about 5 outlets and one light. It would be a light load, running small things, no heaters or med/large equipment. #12 provides reasonable performance up to about 100′ with general loads like you describe.

How long can you run 12 gauge wire?

The following are the maximum lengths of cable you can use while still maintaining a 3 percent voltage drop for the given wire size (AWG) and circuit voltage….For 120-volt circuits:14 AWG50 feet12 AWG60 feet10 AWG64 feet8 AWG76 feet6 AWG94 feetOct 20, 2019

Can 12 gauge wire handle 30 amps?

No. 12 gauge wire is rated for a maximum of 20 amps. You need a minimum of 10AWG wire for 30 amps.

Can I use 14 gauge wire on a 20 amp breaker?

NEC 240.4(D)(3) states that 14 AWG must be protected at 15A. You can not use 14 AWG anywhere on a circuit that has a 20A breaker. If you are putting 15 amp receptacles on a 20 amp circuit with 12 gauge wire, then you MUST use the screw terminals, not the back stab terminals. … Just use the side terminals.

Does an extension cord use power if nothing is plugged into it?

The answer to most people who would ask this question or read the answer is “No.” To use up electricity, it has to flow and it cannot flow in an extension cord that nothing is plugged into.

Is it OK to mix 12 and 14 gauge wire?

Anyway, the first subject is a bit touchy because it makes it difficult to perform an inspection when all of the wires coming into the panel are 12 but many of the circuits have 14 in them too. There is nothing against code mixing wire size for these circuits as long as the OCPD matches the smallest wire.

How do you run an extension cord in a window?

The easy way: Cut a notch in the bottom rail of one window and in the stool. Put this extension-cord-sized notch in the corner and you won’t see it. Make it so that you can put the cord through this notch and almost close the window but so that it’s sealed when the window is all the way closed. Nobody will see it.

How many watts can a 14 gauge extension cord handle?

Which is better 14 or 16 gauge extension cord?

For blowers will 12 amps or less, use a 16-gauge light-duty cord within 50 feet of your outlet. Go with a 14-gauge medium-duty cord for a higher amp or a greater distance from the outlet. Make sure the cord is rated for outdoor use—look for a “W” on the jacket.

Can you use an extension cord permanently?

If you need to permanently connect an electrical device, you should use approved wires and/or cable assemblies installed in an approved manner. As Tester101 says, extension cords are not meant for permanent wiring.

How many amps does a refrigerator use?

A typical refrigerator draws 725 watts, according to the United States Department of Energy. Divide that number by 120 volts, which is the voltage of your power supply, to get the current that the refrigerator draws in amperes. A 725-watt refrigerator draws 725/120 = 6 amps.
