What can I do about new Friedrich air conditioner's cord which is 2 feet too short looks ugly in reaching outlet does a 9' extension cord risk harming the unit violate the warranty?

I don't know about the warranty, but the unit will run fine using an extension cord IF you buy one that is heavy-duty. Look for a cord that is 12 gauge or even 10 gauge. If you use a 14, 16, or 18 gauge cord (these may be too small), the unit could be damaged.


A gauge 14 extension cord can safely carry 15 A What will happen if several appliances drawing a total current of 18 A will be connected to it?

A 14 gauge extension cord can safely carry 15 amps, but not very far. Number 14 gauge extension cords are only rated for about 13 amps according to the labels on the cord. This is because the insulation is not intended to withstand the heat of currents above this level. Running this cord over 50 feet or loading it to 18 amps would be unacceptable.The likelihood of the cord maintaining the 18 amps for any amount of time for the high current to do any damage to the insulation of the cord is not very great. Extension cords are only an extension of the 15 amp wall circuit that they are plugged into. On overloading the extension cord by that amount the overload will trip the 15 amp supply breaker. An example of this is jamming a circular handsaw when it is plugged into the end of a 50 foot extension cord. The next action that is taken is to reset the tripped breaker.


Who invented the first electrical extension cord?

The extension cord was invented in 1904 by S. W. Atherton, an American inventor and electrical engineer.


How do you make extension cord for generator with different plugs?

To make an extension cord for a generator with different plugs, first, ensure that the generator's output voltage and amperage match the requirements of your appliances. Use a heavy-duty outdoor extension cord with appropriate wire gauge for the load. Cut the cord to your desired length, and strip the ends to expose the wires. Attach a compatible plug for the generator on one end and the appropriate connector for your appliances on the other, ensuring proper wiring for hot, neutral, and ground connections. Always follow safety guidelines and local electrical codes.


Can I use a short extension cord if it is rated the same as the power cord?

Yes, you can use a short extension cord if it is rated for the same voltage and amperage as the power cord. However, ensure that the extension cord is also suitable for the intended use, particularly regarding its length and the load you plan to connect. Always check for any signs of wear or damage before use to ensure safety.

What is the recommended length and type of extension cord to use for a dryer plug extension cord?

The recommended length for a dryer plug extension cord is 25 feet or less, and it should be a heavy-duty, 10-gauge wire extension cord to handle the high power requirements of a dryer.


Why is the voltage at the end of a long extension lead used with an electric drill less than the mains supply voltage?

Resistance in the length of wire that makes up the extension cord causes voltage to drop. But it needn't be a problem with the right extension cord. For an electric drill, up to a 25 foot cord of 16 gauge wire will cause a voltage drop so small as to be negligible. For 50 feet, switch to a 14 gauge cord. For heavier power tools (circular saw in particular) you should use a 14 gauge extension from the get-go.


Does a long extension cord draw more power than a short extension cord?

No. However, a longer extension cord has higher resistance for a given wire gauge or size compared to a short extension cord and the voltage at the load device may drop so low that it doesn't work properly. This may also be accompanied by a noticeable rise in the temperature of the extension cord. As a rule, use the shortest extension cord that will get the job done. If the extension cord must be long, use one that has heavy gauge wire to minimize voltage drop at the load.


What is correct extension cord amp load for a 5500 volt generator?

For a 5500-watt generator, you should use an extension cord rated for at least 20 amps to safely handle the electrical load. Make sure the extension cord is in good condition and of the appropriate gauge to prevent overheating and ensure safe operation.


What amperage extension cord should be used for microwave?

It is recommended to use a heavy-duty extension cord rated for at least 15 amps for a microwave. Make sure the extension cord is of the appropriate length and gauge to avoid overheating and potential fire hazards. Always check the manufacturer's guidelines for the specific microwave model.


What is the recommended length and gauge of extension cord for a lawn mower to ensure safe and efficient operation?

For a lawn mower, it is recommended to use an extension cord that is at least 14 gauge and 50 feet long to ensure safe and efficient operation.


How long can you run an electric extension cord?

It depends on the gauge of the wire, the length and the total current draw of the appliances. You said "heavy duty outdoor extension cord" so I'll assume 12 gauge wire. You can run a MAXIMUM of 20 amps for a MAXIMUM of 100 Ft on that wire. If the current draw goes up, so should the wire size. If the distance goes up, so should the wire size. 10 Ga wire - 30 amps for 100 Ft.


What cords do you need to power a TV?

Any extension cord that has the capacity to carry the amperage that the TV draws. Any extension cord that the hardware store sell will be sufficient to do the job.


What gauge extension cord for sump pump?

For a sump pump, it's generally recommended to use a heavy-duty extension cord with a gauge of 12 or 14. A 12-gauge cord can handle higher wattages and longer distances, making it ideal for most sump pumps, which typically require a significant amount of power. Ensure that the extension cord is rated for outdoor use if it will be exposed to moisture. Always check the manufacturer's specifications for your specific sump pump to ensure compatibility.


What size extension cord should you use for your 120 volt 1725 watt iron?

#16 <<>> To load an extension cord to 1725 watts depending on the length of the cord, the bare minimum should be #14. A better size cord and my recommendation would be a #12 wire size extension cord.
