For older homes throughout the nation, electrical capacity can be a concern. Now more than ever, homeowners are using more electricity than their homes were originally built to handle.
From upgraded appliances, HVAC, and smart devices to EV chargers and home offices, modern-day lifestyles can put more demand on an older electrical system.
In this article, the experts at Tudi Mechanical help homeowners determine whether their home is experiencing an electrical capacity issue, including signs that they may need to consider an electrical panel upgrade for their safety and convenience.
What Electrical Capacity Means for Your Home
When assessing a home electrical system, electrical capacity refers to how much power the system can safely support. This is critical for both electrical panels and circuits.
The electrical panel acts as the hub of your system, sending power to individual circuits. These have their own circuit capacity, or the amount of electrical current they can safely carry.
If the amount of power your modern household uses exceeds your panel’s capacity or you have appliances that require a circuit with higher capacity, you may experience electrical issues or even be at risk of electrical fire hazards.
Signs of Electrical Capacity Issues
Your Breakers Trip More Often Than They Used To
One sign that you may be exceeding your home’s electrical capacity is frequent circuit breaker trips. Tripped circuits are a sign that your circuit is overloaded, as the system shuts the circuit down to protect against overheating and damage.
That’s why breakers are considered safety devices and why repeated trips should not be ignored.
Lights Flicker When Appliances Turn On
If you turn on a high-power appliance and your lights temporarily flicker or dim, you may be drawing too much power. This is a power-demand issue and is common at startup for large appliances such as:
- Air conditioners
- Microwaves
- Refrigerators
- Washing machines
- Dryers
You Rely on Extension Cords or Power Strips Every Day
A lack of outlets in a dated electrical system can’t be solved with extension cords and power strips. While these fixes provide additional outlets, they don’t increase the circuit’s capacity. This can lead to overheating and other issues that put your safety at risk. Instead, homeowners can improve convenience by adding capacity and circuits to meet their daily outlet needs.
Your Panel Does Not Support New Home Upgrades
Not all electrical panels were built to support advanced technology. Upgrades to your home may require more panel or circuit capacity than you currently have, such as:
- Electric vehicle charger installation
- Backup generator installation
- Heat pump or ductless mini-split installation when you previously relied on gas heating
- Electric tankless water heater installation
- Smart home system installation
That’s why Tudi Mechanical offers electrical panel upgrades to support these advanced systems.
Your Aging Home May Not Be Built for Modern Electrical Use
The electrical industry has changed significantly in the last several decades. Homes built in the 20th century often have panels, wiring, or circuits designed for a much lower electrical demand.
That’s why homeowners are wise to have their system evaluated before adding major new electrical loads. Issues like dated wiring or insufficient power can then be addressed proactively to reduce your risk of electrical issues.
You Notice Warm Outlets, Buzzing, or Burning Smells
Overloaded outlets in your home can be dangerous. This often creates excessive electrical demand in the circuit and can cause overheating. Scorched outlets, buzzing sounds, or burning odors are clear signs.
An overloaded circuit is a serious sign of electrical trouble. To protect your safety, stop using the affected outlet or circuit and call a professional at Tudi Mechanical.
