It is time for the regular electrical inspection. You might ask yourself, “How can I open my breaker box safely without damaging the installed circuit breakers?”
The main electricity supply for your house comes from your main electrical panel. Contact with the panel’s internal or external surfaces is dangerous without the proper protective gear. Managing your breaker box involves many different considerations as well.
Before we start the discussion, here is a list of the equipment you need.
Things You Will Need
Electric Drill or Screwdriver
When installing a service panel, contractors make sure the cover is closed tightly. They take these precautions to safeguard the electrical box’s circuit breakers and live wires. Therefore, you will require additional force to assist you in removing the screws holding the cover in place to open a locked breaker box. The electric drill works in this area.
However, I advise using a flat head screwdriver in some circumstances if a drill is not available. With this tool, you’ll have to use more force, but don’t worry—the result is the same.

You will be protected from electrically charged surfaces by using this device. Anomalies, such as arc faults, ground faults, or short circuits, are typically present when a homeowner needs to open up his breaker box.
You will require a multimeter in these circumstances to check the breaker box. It doesn’t matter whether you prefer analogue to digital or vice versa as long as the multimeter accurately detects electricity. However, my preferred option is a digital multimeter. Only as a backup do, I use the analogue ones.
Personal Protective Equipment
Make safety your top priority at all times, as I’ve said! Wear protective eyewear, insulated gloves, and boots before working in an electrical environment. You can survive safely even with just the bare necessities.
There may be concepts you are unfamiliar with when learning to open a circuit breaker box. Keep yourself safe whether you’re working on this project with an electrician or contractor. Wearing protective equipment against electrical hazards is safe.
I dissuade a straightforward do-it-yourself guy from doing all the work before you continue. High voltage is involved here, so at the very least, have a professional with you.
If you’re a simple house owner, do yourself a favour and stop going it alone. They are more knowledgeable and better equipped to deal with potentially fatal shocks.
Steps to Opening a Breaker Box
There are two methods for opening an indoor breaker box.
The light-off technique is the first. Turning off the main breaker switch allows you to work freely in your service panel without worrying about electrocuting or unintentionally shifting some circuit breakers. After your work, ensure every CB is still attached to its bus bar, and everything will be fine.
Let’s also imagine you are working on a live panel where you must keep the appliances running. This situation typically occurs in office settings or when people work remotely. You’ll have to work more careful while doing this, though. Accidents and inconvenience to those who share the building are what we are trying to prevent here.
This tutorial will cover the second strategy because it demands more work.
Clean Up Your Workspace
You must react quickly during this electrical maintenance. Because you are not aware what might be happening inside the breaker panel, you should be as prepared as an athlete if you encounter a dangerous surprise.
Clear the area of the floor where you’ll be working. Make sure your path is clear of any puddles or tool piles. In the event of arc faults or explosions brought on by a bus bar failure, you must move or leave the area immediately.
Check Your Panel Cover’s Surface
Check all the panel’s exteriors that you will come into contact with a multimeter. Avoid using the “handyman” technique used by some DIYers, in which they touch or feel for live currents outside their box with their bare hands.
You should be concerned if a panel cover is rusted because it indicates a more serious issue.
Determine The Weight Of The Cover
Find out what the cover’s potential weight is. Consider yourself capable of handling it alone. Before opening the breaker box door, this step is essential.
Although some panels are lightweight materials, others are thick steel that can be very heavy. As soon as you take the screws out, you don’t want to drop them. Having a second hand available to help you would be preferable.
Drill The Bolts Out
Always keep in mind that you should loosen the bolts at the bottom of the load centre and work your way up as you separate the cover from the main panel. Remove the corner screws at the bottom before moving on to the middle ones. Follow the same steps to close the box’s upper side, but take your time.
Circuit breakers can occasionally be delicate. Nudge the panel door with your hand when you take out the final bolts. You don’t want your cover abruptly leaning and moving all CBs if the central power source is on.
Remove The Panel Cover
A steady hand is necessary for this step. Also, suggest it to your partner, if you have one. Pull the cover back straight in line with all the circuit breakers by grabbing the top and bottom portions of the cover. Keeping all of the breakers intact is the objective here. He can help you move it out of the way if you feel like you are pulling something.
Place The Panel Cover in a Secure Location
The panel’s cover and the bolts should then be placed in a secure location. I strongly advise looking for a quiet location where it won’t bother you or the panel inspector. Make another live wire or surface test with your multimeter after revealing or opening the outside breaker box, then perform any required maintenance.
Do you think I addressed your query? Whenever someone asks me how to open my breaker box, I advise them to get ready with a multimeter, an electric drill, and a complete set of electrician’s protective gear.
I can only recommend that you stay away from your circuit breakers, which is the most crucial piece of advice I can give you. It greatly aids in the process if you remove the panel cover bolts starting with the bottom screws. Let a qualified person oversee you as well.
