Insulated screwdriver
Voltage tester
Lockout tagout devices
Safety gloves
Safety glasses
Lock and tag
Flashlight
Small pouch or tool bag
Tip: Always look at your tools before you use them. Make sure they are not broken. Broken tools can hurt you.
You will use these tools to open the panel and check for power. You also need them to put on the lockout tagout devices. Never try to put in a circuit breaker lockout without the right tools. The panel can be risky if you do not follow the steps.
There are different lockout tagout devices for different circuit breakers. Each device is made for a certain breaker type. Here is a table to help you pick the right one:
| Device Type | Use Case | Tool Needed |
|---|---|---|
| Clamp-on | Fits most single-pole breakers | No |
| Snap-on | For specific breaker brands | No |
| Universal | Works with many breaker types | Sometimes |
| Tie-bar | For double-pole breakers | No |
You need to match the lockout device to your circuit breaker panel. Always read the manufacturer’s instructions before you put in a circuit breaker lockout. This helps you not make mistakes. If you do not know which device to use, ask a supervisor or look at the panel label.
Note: If you use the wrong device, the lockout might not work. Always check before you start the circuit breaker installation.
You always need to wear personal protective equipment before you start. This keeps you safe from electrical dangers and helps you follow OSHA rules. Put on safety gloves and safety glasses to protect your hands and eyes. These keep you safe from sparks and sharp things. Wear insulated shoes if you are near live wires. Use a hard hat if things could fall on you.
Tip: Look at your equipment before you use it. If it is broken, it will not keep you safe.
Good safety starts with the right gear. Never skip this step. OSHA says you must wear personal protective equipment every time you do energy control work.
Before you put in a lockout device, follow some steps. First, read the lockout tagout procedures for your job. These steps help you control dangerous energy and keep people safe. Next, tell everyone nearby that you will start a lockout. This warning helps stop accidents.
Always turn off the power at the main breaker. Use a voltage tester to check that the power is off. Do not trust the breaker label by itself. Test every time. OSHA says you must check that all energy is off before you start. This is part of OSHA rules and helps you stay safe.
Put a tag on the breaker to follow the tagout process. The tag tells others not to turn the power on. Use a lock to keep the breaker off. This lockout step is important for controlling dangerous energy.
Note: OSHA and NEC 110.25 say you must do these steps for every lockout. Always use the right steps for your equipment.
If you follow these safety steps, you help keep everyone safe. You also follow OSHA rules for lockout tagout procedures.
Start by finding the correct breaker in the panel. Look at the labels on the panel door. These labels help you match the breaker to the equipment you want to work on. If you do not see a label, check your work order or ask your supervisor. You must always identify the right breaker before you install a circuit breaker lockout. This step keeps you from shutting down the wrong equipment. It also helps you follow lockout tagout procedures.
Tip: Use a flashlight to see inside the panel if the area is dark.
After you find the right breaker, turn it off. Push the switch to the OFF position. This step starts the shutdown process. Always use one hand to flip the breaker. Keep your other hand away from the panel. This method lowers your risk of shock. Once you turn off the breaker, use a voltage tester to check for power. Never skip this step. You must verify that the equipment is disconnected before you move on. This step is part of every lockout tagout procedure.
Now, choose the correct lockout device for your panel. Look at the breaker type and size. Use the table from earlier to help you pick. Most clamp-on lockout devices fit single-pole breakers and do not need tools. If you have a double-pole breaker, you may need a tie-bar device. Always read the manufacturer’s instructions before you install a circuit breaker lockout. This step makes sure your lockout fits and works right. Using the wrong device can make the lockout fail.
Open the panel door. Place the lockout device over the breaker switch. Make sure it covers the switch fully. For clamp-on devices, push the clamp onto the breaker. Snap-on devices click into place. Universal devices may need a small screwdriver. Follow the instructions for your device. You must attach the lockout device so the breaker cannot move. This step helps you isolate the machine from the energy source. If you do not attach it right, the lockout will not work.
Note: Most clamp-on lockout devices do not need tools for installation.
After you attach the device, put a lock through the hole in the lockout. Close the lock and keep the key with you. Hang a tag on the lock. Write your name, date, and reason for the lockout on the tag. This tag tells others not to touch the breaker. The lock keeps the breaker off. The tag gives information. You must always use both lock and tag to follow lockout tagout procedures. This step is called apply lockout tagout.
| Step | Action | Why It Matters |
|---|---|---|
| 1 | Lock the device | Stops others from turning on |
| 2 | Tag the device | Warns others about the work |
You must verify isolation before you start work. Try to turn on the breaker. The lockout device should stop the switch from moving. Use your voltage tester again to check the panel. Make sure there is no power. This step helps you verify isolation and keeps you safe. If you see any power, stop and check your steps. You must verify that the equipment is disconnected before you touch any wires or parts. This step finishes the lockout tagout process.
Alert: Never skip the verify lockout step. It is the only way to make sure the panel is safe.
You have now finished all the steps to install a circuit breaker lockout. Always follow the procedure in order. Each step protects you and others. If you have questions, check the manufacturer’s instructions or ask your supervisor. When you install a circuit breaker lockout the right way, you keep your panel and your team safe.
You may face some problems when you install a tagout device on a panel. Sometimes, the tagout device does not fit the panel breaker. You might see that the tagout slips or does not stay in place. The tagout label may fall off the panel or become hard to read. You may also forget to test the panel for power after you finish the tagout process. If you skip steps, you can miss important OSHA rules. Sometimes, other workers do not see your tagout on the panel and try to turn on the breaker. These issues can put your safety at risk.
You can fix most tagout problems with a few simple steps. Always check the tagout device before you use it. Make sure it matches the panel breaker type. If the tagout does not fit, try a different device. Use a strong tagout label and write clearly. Place the tagout label where everyone can see it on the panel. Test the panel for power every time you finish the tagout. Remind others about your tagout on the panel. Follow OSHA rules for every tagout job. If you see a problem, stop and fix it before you move on.
Tip: Keep extra tagout devices and labels in your tool bag. This helps you solve problems fast.
