How to wire a 220 outlet for a welder can be challenging, especially if you don’t know. It would help if you had a guide to take you through the entire process. Since you will be handling electrical points, there is a need to take precautions and do things by the book. This article has a complete guide that can comfortably and efficiently direct you throughout the wiring process.
This is something that you can do for yourself rather than calling for an expert. You will save some money that you could pay an electrician to perform the task. Let us have a look at these steps on how to wire a 220 outlet for a welder.
How to wire a 220 outlet for a welder – step by steps guide
Step 1: switching off the circuit breaker
This step involves nothing more than locking off the handle after powering off the circuit breaker. This step is simple as what you need to do is to ensure the circuit breaker is dead. Remember, this action should come before touching anything. After everything is set, move to the next step.
Step 2: Removing the metal cover
Under this step, make sure you remove the metal cover. Doing so is essential to enable you to access breakers easily. Now that the circuit breaker is off insert in a 50-amp-two pole breaker in the box. More so, ensure that this box can accommodate your two-pole breaker.
Inspect to determine whether there are two spaces to hold the two-pole breaker. Once you are through with the inspection process, visit the nearest electrical supply or hardware store. You will have to buy some materials such as an outlet, a beaker, and electrical wires.
Step 3: Screwing two-gang box on the wall
Now that you have the necessary materials, it is time to fix the gang boxes on the surface tightly. Make sure that the packages are tightly held in place; they should not move. For this case, you can use screws.
Step 4: Fixing the Wires
This is the critical step that involves attaching and fixing the wires. Here, you need to have not less than six inches of wires in the receptacle box. Try as much as possible to expose some sheathing in the two boxes. This involves a 2-gang box and the circuit breaker.
After everything is in place, it is now time to use the same/similar cable ripper. Pull out about six inches of plastic cover from the wire. This wire should be the same as the one in your 2-gang box. After you are through with everything in this step, move on to step 5.
Step 5: pulling out 12-inch plastic sheath off the wire
This is the most straightforward step that only requires you to use the cable ripper to remove the plastic sheath (12 inches) off the wire. Remember, you will use this side of the wire in the circuit breaker box.
You should also be keen under this step not to interchange the measurements. Failure to maintain the right measures will ruin the entire process.
Step 6: Stripping off the 1-inch sheath
Take your wire stripper and strip off the 1-inch sheath. Under this step, observe some instructions not to strip off more than a 1-inch sheath.
Step 7: Connecting the wire
Suppose you are through with the stripping off process. Connect one end of the wire to the two-gang box and the other end in the circuit breaker box. This step also involves implementing the connectivity of the cables.
It would help if you committed yourself to connect wires in the 2-gang box, ensuring there is a link with the outlet.
To achieve this, you need three wires, i.e., a black, bare one and red. The bare wire should be the ground. However, sometimes you may require the fourth wire, which is white, to act as neutral. However, it is not a must.
Therefore, to prevent some electrical mistakes, wrap and tape the white wire and seal it in the 2-gang box. Sealing should secure to curb the chances of electrical shocks.
Step 8: Covering the wire tips with a non-corrosive agent
Now that the wires are in their specific places, it is time to protect their tip with a non-corrosive material. This will keep them off from corroding.
Step 9: Connecting the wires to the receptacle
It is time to take the wires and connect them to your receptacle. Use the correct screw to hook up individual colored wire. You should attach the red and black wires to the 2-prong terminal. Connect the bare one to a ground terminal.
Don’t forget to place it together with the screw facing up. Adequately cover it to make your work look professional. So, cover it enough.
Step 10: Joining the three wires to the breaker
Under this step, you will have to connect your wires to the breaker. More so, you will need another wire, fold and securely keep it in the breaker box. You will also have to strip off the wires before covering the tips with non-corrosive stuff.
Doing so will make sure that wires are long-lasting, free from corrosion. Besides, covering their tips will also prevent some mistakes. Your job will look professional.
Step11: Hooking up the Ground Wire
This becomes the last step that you have to hook the ground wire up. More so, you should hook up/attach well the red and black cables following the breaker manual. After all the above steps are successful, you are through.
Frequently asked questions
Why should I have to cover the tips of my wires?
Protecting the wire tips with non-corrosive material will keep them off from corroding. Besides, your job will look professional.
What are the wires that I need when wiring a 220 outlet for a welder?
You need three wires, i.e., a black, bare one and red. The bare wire should be the ground. However, sometimes you may require the fourth wire, white, to act as neutral, though it is not a must.
Hopefully, this step by step guide helps you with how to wire a 220 outlet for a welder. What you only need to be careful about is to use the right materials. Failure to use the recommendable wires may overload the circuit and cause a fire eruption. Besides, the entire equipment could not be long-lasting.
