Do you need to plug in a generator but don’t have an appropriate extension cord?
With just a few basic supplies, you can easily make your own 220-volt extension cord for the generator.
This project is ideal for keeping you prepared for power outages and emergencies. So, how to make a 220 volt extension cord for the generator? Let’s See!
How To Make A 220 Volt Extension Cord For Generator
If you need to plug in a generator but don’t have an appropriate extension cord.
It’s simple to make a 220-volt extension cord for the generator if you have the necessary equipment.
You’ll just need a few basic supplies. Now, to make your own 220-volt extension cord for the generator, follow the below steps:
What You’ll Need:
- Electrician’s screwdriver
- Male and female extension cord plugs
- Heavy-duty outdoor extension cord
Generators use fossil fuels such as gas or diesel to generate electricity.
They’re usually noisy and produce deadly carbon monoxide fumes when used in emergencies or areas without a connected supply.
For safety reasons, the generator is frequently kept at a safe distance from the appliances it supplies.
Step 1: Determine The Load
Determine the maximum amount of load your appliances will put on the generator.
Every instrument draws electricity from the generator, so add together loads of all the connected appliances.
A plate should be attached to each appliance, indicating the number of watts it can carry.
For example, if a 5-kW heater is powered by a 2-kW drill and a 100-watt light bulb, the total load will be 7100 watts.
Step 2: Calculate The Current Rating
The minimum current rating of a cable is calculated by dividing the load by the voltage.
North American homes are typically fed with 120 and 220 volts. Generators may provide either or both voltages.
For example, a generator supplying 120 volts to a load of 7,100 watts.
The circuit will require a cable with a current rating of (7,100 / 120) amps, which is roughly 60 amperes.
Use an outdoor rated cable that is greater than your calculated current capacity.
Step 3: Disassemble The Plugs
Disassemble the fittings and attach the plugs to the cord.
For you to work on the end of the cord without getting in the way, feed a sufficient length of cable through each housing.
Step 4: Position The Cord
Remove any existing insulation from the wires. Insert each plug base, so the insulated part of the cord is level with the cable grip.
The ends of the wires should reach the terminals. Stretching or bunching up the wires might cause them to break.
If your wiring isn’t correct, trim it down or remove more of the outer insulation to reveal a longer wire length.
Step 5: Use A Knife
Using your hands, work the wires towards each other. Use a knife or wire strippers to bare the final quarter inch of each wire.
Twist together all of the exposed wire fibers to make a firm wire rod. Keep in mind that a loose connection will create sparks and cause a fire.
Step 6: Attach The Wires
Attach the wires to the plug terminals. Generator cords must be connected using polarized wiring in order for them to connect to the correct terminals.
Connect the “hot” black or red wire to the brass terminal and the “neutral” white wire to the silver terminal.
Attach the ground (bare or green-covered) wire to the GND terminal.
Step 7: Protect The Cord
Fasten the cable securely in the cord clamps to prevent it from being yanked free out of the sockets.
Replace the housing on each plug and check that the terminals are secure. The cord is now suitable for use.
As you can see, making your 220-volt extension cord for the generator is not difficult. Just follow the steps above, and you’ll have your 220-volt extension cord in no time.
You can use this cord to safely connect your generator to your appliances in case of an emergency.
How To Determine The Power Of An Extension Cord?
An extension cord’s power is determined by two factors: the current and the voltage.
The current is how much electricity can flow through the cord and is measured in amps.
The voltage is how much force the electricity has and is measured in volts.
To calculate the power of an extension cord, you need to know both the current and the voltage.
When you calculate the power, you need to multiply the voltage by the current.
For example, if you have a cord with a voltage of 120 volts and a current of 10 amps, the power would be 1200 watts (120 x 10).
Note that, not all extension cords are created the same. Some extension cords are only meant for light duty.
While others are meant for heavy duty. Before buying the cord you need to Check the ratings on the cord. Because it ensures the rate for the power you need.
Now that you know how to determine the power of an extension cord. It’s simple to discover which one is best for you.
If you prepare ahead of time, you’ll be sure to have the power you require when you need it.
Tips For Choosing And Using An Extension Cord
Extension cords are required for both indoor and outdoor use. Choose the correct type of extension cord for your needs.
There are different types of cords for various purposes. Make sure you pick the right one for your needs. Here are some tips for choosing and using an extension cord:
- Don’t overload the cord. Check the ratings on the cord before you plug anything in. Overloading the cord can cause it to overheat and start a fire.
- Keep the cord away from heat sources. Heat can damage the cord and cause it to catch fire.
- Never use a cord that is damaged in any way. Replace the wire with a new one if it has been damaged.
- Look for any damage to the cord itself. Remove the wires from within if you find a cut in it, and do not use it. Additionally, if the cut is minor, you may mend the cord with electrical tape.
- Before connecting them to a power source, double-check and make sure all connections are secure and tight.
- Don’t pull the extension cord when you’re done. To divorce, grab the plug instead of the cable.
- There are handles on some wires to make it simpler to remove them.
- Try to keep any connections on the cord as far away from the ground as possible. They should not be exposed to moisture or standing water.
- You can also use adaptors to route the signal from one outlet to another by running a single line through two outlets and connecting them in series with each other.
- If the cord or adaptor becomes hot, cease using it immediately. When excessively hot, some adaptors can melt and cause a circuit fault.
- To avoid coils while in use, fully unwind the extension cords.
Well-made extension cords will have strain relief collars protecting the wire entering the plug.
The collar absorbs any tugs on the cord so that the cables don’t get pulled out of the plug.
Extension cords are a handy tool to have around, but they need to be used safely.
Be sure to follow the tips above to get the most out of your extension cord and keep yourself safe.
Is An Extension Cord Suitable For Use With A Welder?
You can use an extension cord on a welder. But you need to make sure that the cord is rated for the power you need.
Most welders require at least a 50-amp circuit. So, you’ll need a heavy-duty extension cord of the appropriate gauge.
Before you go shopping, make sure you double-check the rating on the cable. Because of the high power requirements, it’s best to use a heavy-duty extension cord for your welder.
Is It Cheaper To Make Your Own Extension Cord?
It depends. If you have the materials on hand and you know how to make an extension cord, then it may be cheaper to make your own.
But purchasing a ready-made extension cord may be more affordable if you need to buy all the materials. So it really depends on your individual circumstances.
Can You Use An Extension Cord For A TV?
Yes, you can use an extension cord for a TV. However, it’s critical to double-check that the cord is qualified for the power you require.
Most TVs require at least a 10-amp circuit. So, you’ll need an extension cord that can handle that much power.
Besides, it’s always a good idea to have a few extra feet of cord so you can move the TV around if necessary. It’s always good to have too much cord than not enough.
Extension cords are a necessary part of life, both indoors and out.
That’s why it’s critical to select the best one for your needs. You can use this guide to help you select the right extension cord for your needs.
After reading this article, we hope you know how to make a 220-volt extension cord for a generator.
So be careful when using extension cords, and always follow the safety guidelines.
