Why Do Circuit Breakers Need Maintenance?
Circuit breakers transfer voltage and current through a facility's cabling and equipment. This transfer creates heat that can corrode or melt insulating materials and disrupt electrical connections.
Proactive maintenance allows these safety devices to function properly, minimizing energy wastage and costly repairs. Here are the top reasons why your industrial circuit breakers need preventive maintenance:.
Overheating
Overheating circuit breakers can cause an electrical fire, so this is a serious issue. A hot circuit breaker should always be inspected by West Palm Beach Electrician. If you smell a burning odor while inspecting your breaker panel, shut down your power immediately and call an emergency service. The odor produced is due to the burning of insulation and wires.
A common reason for a breaker to overheat is an overload of electricity. This is caused by plugging too many gadgets into a single circuit. When this happens, the internal sensing mechanism in the breaker overheats, and it automatically shuts off the circuit. This is a good thing, as it helps prevent electrical fires.
Another problem that causes circuit breaker overheating is a short circuit. This occurs when a black “hot” wire in an outlet makes contact with a white “neutral” wire. This sends a massive amount of current through the circuit, which overheats the internal sensing mechanism and trips the breaker. A short circuit may also occur when household wiring degrades over time, and the insulation on a wire frays or cracks, allowing bare wires to touch.
Lastly, the overheating of a circuit breaker can be the result of an arc fault. This is a very dangerous situation that can cause fires, electrocution, and property damage. If you suspect an arc fault, then shut down your power and contact a licensed electrician immediately.
It is important to maintain your electrical system and have it inspected at least once a year by an electrician. This will help to reduce the likelihood of overheating and extend its life span. Performing preventative maintenance on your circuit breakers will save you time and money in the long run.
While a proactive maintenance approach has its advantages, it can sometimes be cost-prohibitive. The condition-based maintenance approach, on the other hand, allows facility teams to optimise equipment performance and safety while minimizing costs. It takes into account the specific environmental and operational conditions that affect breaker ageing, and it provides more accurate and actionable data. It also includes IR testing, which is an effective way of monitoring a circuit breaker’s health.
Overloading
When circuit breakers are not properly maintained, they can begin to malfunction. These malfunctions can lead to overheating and arcing that creates sparks and buzzing noises and puts the facility at risk of a fire. In addition, overheating can cause damage to secondary equipment that can be costly to repair. This is why many facilities take a preventative approach to maintenance that includes regular inspections and servicing, including retesting circuit breakers.
The goal of this type of maintenance is to reduce the probability of failure and extend the life of the circuit breaker. This is often done by using scheduled maintenance schedules that take into account environmental and operating conditions that affect aging. This method can be expensive, but it is also the most effective way to keep the electrical system up and running smoothly.
A common problem that can cause a circuit to overload is too many devices being plugged into one outlet. In the home, this can be solved by moving some of the appliances to another general-purpose circuit or by using extension cords for temporary use only and not fastening them to outlets. The longer-term solution is to install new dedicated circuits that can handle the load of the largest devices and avoid overuse.
In the workplace, overloaded circuits can result in lost productivity and damage to secondary equipment, causing costly downtime. Regular inspections can help identify efficiency issues that can be addressed to prevent overheating and overloading and extend the lifespan of industrial circuit breakers. In addition, pro-active maintenance can ensure compliance with safety regulations and industry standards to minimize the risks of accidents and fires.
Depending on the type of circuit breaker, it may be possible to seek certification that indicates adherence to specific quality and performance standards. This can be particularly helpful in facilities that are heavily regulated or require the highest levels of reliability for critical applications such as hospitals and data centers. In some cases, it may even be necessary to source only certified circuit breakers. This is because there have been instances where fraudulent companies have sold used or refurbished circuit breakers as brand new parts, with the purchaser unaware of their true condition until the breaker fails.
Loose Connections
If a circuit breaker isn’t properly exercised, its operating mechanism can seize up, making it unable to open and close. This prevents the circuit breakers from clearing a fault, which could result in a fire. To avoid this, a facility should regularly perform visual inspections and routine exercise of the operating mechanisms using primary injection testing or push-to-trip (if equipped) to ensure that they are working as intended.
Another potential problem with older circuit breakers is that their internal connections can become loose over time due to aging, vibration, or just plain wear and tear. The first sign of a loose connection is often an unusual burning smell. If you notice this, shut off the power to the affected circuit and call an electrician right away for an inspection.
Loose internal connections can also be caused by wires that aren’t properly connected to the breaker switches. If this is the case, it’s important to turn off the power to the circuit and remove the switch cover, then use a wire nut or other approved connector to ensure the wires are tightened properly. It’s also a good idea to check for any pass-through connections inside the panel box, where wires may connect from one switch to another via a screw terminal or wire nut.
Finally, it’s a good idea to periodically check the electrical connections on each breaker by using an infrared scan. An IR scan will help identify hot spots and areas of resistance that may indicate overheating or loose wiring, which can lead to failure of the breakers or other equipment in the circuit.
It’s also a good idea to lubricate the moving parts on a regular basis. This can reduce friction and increase the efficiency of the breaker. It can also help to extend the life of the breaker by reducing the amount of heat it generates. It’s important to use a good quality lubricant that is designed for use on electrical systems. The right lubricant can also help to protect against corrosion and extend the lifespan of the switch.
Damage
A circuit breaker is inside the electrical panel box that controls everything from appliances to lamps and light fixtures. It prevents electrical surges and fires by limiting the amount of electricity that goes into your building. It also prevents overheating by cutting off the flow of power when too much heat is generated. But like anything in your home, it will eventually need maintenance to ensure that it is working properly. The most important sign that a circuit breaker is in need of attention is when it fails to remain in the “reset” mode. Other signs that it needs to be maintained include a burning smell coming from the electrical panel, it is hot to the touch, there is physical damage or if it trips frequently to name a few.
Faulty circuit breakers can lead to electrical fires, so it is important that they are functioning correctly at all times. Regular maintenance and inspections will help identify potential problems before they become dangerous.
When a circuit breaker is damaged, it can no longer limit the amount of electricity that flows through the circuit. This can result in overheating of the wires or melted connections. This is a serious fire hazard, so it is important that any sign of this issue be dealt with immediately by an electrician.
If you notice a burning smell in your electrical panel, turn off the power to the area and call a professional. This is a clear sign that the breaker is malfunctioning and can cause a fire in your house. It could also indicate that you are using too many appliances on one circuit, in which case the professionals can come and move some of your appliances to another circuit.
The most common way to maintain a circuit breaker is to exercise it on a regular basis. This involves switching it on and off to ensure that the operating mechanism is in working order. This can be done through primary injection testing or, if the breaker is equipped with a push to trip button, by directly operating the trip latch. Other forms of circuit breaker maintenance include cleaning, lubricating and visual and mechanical inspections.
