How To Make A 220 Volt Extension Cord For Generator?
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 to make your own 220-volt extension cord for the generator.
What You’ll Need:
- Knife
- Electrician’s screwdriver
- Male and female extension cord plug
- 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 stripper 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?
To determine the power of an extension cord, you need to consider the following factors:
Wire Gauge:
The thickness of the wire, also known as the gauge, determines the amount of electrical current that can pass through the cord.
The lower the gauge number, the thicker the wire and the more current it can handle.
For example, a 16-gauge cord can handle up to 13 amps, while a 12-gauge cord can handle up to 20 amps.
Length of the Cord:
The length of the cord also affects its power capacity. The longer the cord, the more electrical resistance it has, which means it can deliver less power to the device.
A longer cord will also cause more voltage drops, which can result in reduced performance or damage to the device.
Electrical Load:
The amount of electrical load, measured in watts or amps, that you will be using the cord for should be considered when selecting an extension cord.
If the load exceeds the cord’s capacity, it can overheat and cause a fire or damage to the device.
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:
Choose the right cord for the job:
Make sure the extension cord you choose is rated for the amount of power you will be using.
Consider the wire gauge, length, and power rating of the cord to ensure it can handle the electrical load without overheating.
Check for certifications:
Look for extension cords that have been tested and certified by a recognized organization, such as UL or ETL.
These cords have been tested for safety and meet the necessary standards.
Use outdoor-rated cords for outdoor use:
If you will be using the cord outdoors, choose an outdoor-rated cord that is designed to withstand exposure to the elements.
Keep cords dry:
Never use extension cords that are damaged or wet. Moisture can cause electrical shorts and increase the risk of shock or fire.
Don’t overload the cord:
Never use an extension cord to power devices that draw more current than the cord can handle.
This can cause the cord to overheat and create a fire hazard.
Avoid running cords under rugs or furniture:
Cords that are covered can overheat and create a fire hazard.
Make sure cords are kept in open areas where air can circulate around them.
Unplug cords when not in use:
Unplug extension cords when not in use to prevent them from overheating or creating a fire hazard.
Don’t connect multiple extension cords together:
Connecting multiple cords together can create a fire hazard and increase the risk of electrical shock.
If you need a longer cord, use a single, longer extension cord rather than connecting multiple cords together.
Store cords properly:
Store extension cords coiled neatly in a dry location where they won’t be damaged or create a tripping hazard.
Don’t wrap cords too tightly, as this can cause damage to the cord.
FAQs about how to make a 220-volt extension cord for a generator
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?
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.
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.
