What Are The Warning Signs Of Failing Electrical Panels In Industrial Settings?

Electrical panels play a crucial role in industrial settings’ safe and efficient operation. They control the distribution of electrical power throughout the facility, directing energy to machinery, lighting, and other critical systems. However, like all mechanical and electrical systems, electrical panels degrade over time. When an electrical panel fails, it can result in costly downtime, safety hazards, and significant damage to equipment.  

Recognising the warning signs of a failing electrical panel is essential to maintaining the health and safety of your facility. In this article, we will discuss the key warning signs of a failing electrical panel in industrial settings, the dangers of neglecting these signs, and the role of professional commercial electricians in Denver and commercial electrical contractors providing timely maintenance and repairs.

The Importance Of Electrical Panels In Industrial Settings 

Before delving into the signs of a failing electrical panel, it’s important to understand its role in an industrial setting. Electrical panels also referred to as distribution boards or breaker boxes, are responsible for routing electricity from the main power supply to various parts of a facility. They contain a series of circuit breakers or fuses that protect the electrical system from overloads by interrupting the flow of current when it exceeds a safe limit. These panels are vital for ensuring the safe and efficient operation of machinery, lighting, and other equipment that industrial facilities rely on.  

While electrical panels are built to last, their performance can decline over time. If left unchecked, failing electrical panels can cause equipment damage, production delays, and even fires. Therefore, understanding the signs of a failing electrical panel and addressing them promptly is critical. 

Warning Sign 1: Frequent Circuit Breaker Tripping 

Frequent circuit breaker tripping is one of the most common signs of a failing electrical panel. Circuit breakers are designed to protect electrical circuits from overloading by automatically shutting off the power when there is too much current. While occasional trips can occur due to power surges or faults in specific circuits, regular tripping can indicate more severe problems within the electrical panel. There are several reasons why circuit breakers may trip frequently. One of the most common causes is an overloaded circuit. If too many devices or machines are running off a single circuit, it can overload the breaker, causing it to trip as a protective measure. Another possible cause is a faulty circuit breaker that trips without any overload or short circuit.  

In some cases, a malfunctioning breaker can fail to stay in the “on” position or may trip unnecessarily. Loose or faulty wiring can also create an electrical fault that triggers the breaker. If your circuit breakers are tripping often, it is a clear sign that the electrical panel is not functioning properly. This issue should not be ignored, as it can lead to larger electrical problems, equipment malfunctions, or even fires. Contacting a commercial electrician Denver is essential to diagnose the issue and perform any necessary repairs or upgrades to the electrical panel.

Warning Sign 2: Visible Damage Or Discolouration On The Panel 

Another critical warning sign of a failing electrical panel is visible damage or discolouration. If you notice scorch marks, burnt areas, or discolouration around the electrical panel or its components, it could indicate that the panel is overheating. Overheating is often caused by excessive current flow, usually due to one or more of the following factors: 

• Loose connections: Electrical connections can loosen over time due to wear and tear. Loose connections create resistance, which generates heat, leading to overheating of the panel. 

• Overloaded circuits: If the electrical panel is asked to supply more power than it was designed to handle, it can overheat. This is especially common in facilities that have added new machinery or equipment without upgrading the panel. 

• Age-related degradation: Older electrical panels are more prone to wear and tear. As the panel ages, its components may no longer function efficiently, leading to overheating. 

Visible damage, such as burn marks or discolouration, is a serious concern that should never be ignored. If left unresolved, overheating can cause irreparable damage to the panel and may even result in a fire. If you notice any such signs, it’s crucial to contact an industrial electrical contractor immediately to have the panel inspected, repaired, or replaced as needed.

Warning Sign 3: Flickering Or Dimming Lights 

Flickering or dimming lights in an industrial facility are another clear indication that your electrical panel may be failing. When lights flicker or dim, it typically suggests an issue with the electrical supply, and in many cases, this is related to the electrical panel. Flickering lights can occur for several reasons. One common cause is loose or corroded wiring within the panel. If the wiring is not properly connected, it can cause an intermittent flow of electricity, leading to fluctuations in the brightness of lights.

Another possibility is overloading the electrical panel. When too many devices are drawing power from the same panel, it can cause voltage fluctuations, which can lead to dimming or flickering lights. In some cases, the problem may be with the lights themselves or their fixtures. However, if the flickering or dimming is widespread throughout the facility, it is likely a sign that there is a problem within the electrical panel. This issue should be addressed promptly to prevent further electrical problems, equipment malfunction, and potential safety risks.

Warning Sign 4: Electrical Panel Or Breakers Feel Hot To The Touch 

If you notice that your electrical panel or the individual circuit breakers feel hot to the touch, this is a significant warning sign that the panel is malfunctioning. Electrical panels are designed to operate at safe temperatures, and any noticeable heat buildup indicates that something is wrong. Several factors can contribute to overheating. One common cause is loose connections. If the connections within the panel are loose or corroded, it creates resistance, which generates heat. Another possible cause is overloading the panel.

If the electrical load exceeds the capacity of the panel, it will work harder than intended, leading to overheating. In older panels, aged components may no longer be able to handle the power demand efficiently, leading to excessive heat. If your panel or breakers are hot to the touch, it’s essential to turn off the power and contact a licensed commercial electrician in Denver immediately. Overheating electrical panels are a fire hazard and must be addressed without delay.

Warning Sign 5: Unusual Noises Or Smells 

Unusual noises, such as buzzing, humming, or crackling sounds coming from the electrical panel, are another warning sign of a failing system. These noises are often caused by loose or corroded connections, which can cause electrical arcing. Arcing occurs when electrical current jumps across a gap in a connection, creating heat and noise. In some cases, the noises may also be caused by faulty electrical components within the panel, such as a malfunctioning circuit breaker or an overloaded transformer.

In addition to unusual noises, burning smells are another red flag. If you smell burning or chemical odours coming from the electrical panel, it is a clear sign that something is overheating or melting inside the panel. This issue is usually caused by overloaded circuits, faulty wiring, or deteriorated components. If you notice any unusual smells or noises, immediately shut off the power and contact an industrial electrical contractor for a professional inspection and repair.

Warning Sign 6: Electrical Shocks Or Sparking 

Electrical shocks or sparks when operating equipment or touching outlets can also be a sign that your electrical panel is failing. These issues often arise due to faulty wiring within the panel, which can create an electrical fault that causes current to flow improperly. Loose or damaged wires inside the panel can result in sparking, which poses a significant fire risk. If you experience electrical shocks or notice sparks near your electrical panel, you must take immediate action. Electrical shocks and sparking are dangerous and should be addressed promptly to prevent injury and further damage.

Warning Sign 7: Age Of The Electrical Panel 

While not always immediately obvious, the age of the electrical panel is an important factor to consider when assessing its condition. If your electrical panel is over 25-30 years old, it may be time to replace it, even if it is not showing visible signs of failure. Older panels were not designed to meet the modern power demands of today’s industrial facilities. As electrical equipment has become more advanced, older panels may struggle to keep up, leading to problems like overloads, overheating, and inefficiency.

In addition to the inability to handle modern power loads, older panels may also lack important safety features, such as ground fault circuit interrupters (GFCIs) or arc fault circuit interrupters (AFCIs), which can provide an extra layer of protection against electrical hazards. If your electrical panel is outdated, upgrading to a newer model is a wise decision that can improve the safety and reliability of your electrical system.
