The size of your home’s electrical service is critical to ensuring your household has sufficient power to meet its needs. An inadequate service size can lead to frequent circuit overloads, tripped breakers, and even safety hazards. This article explores the signs of insufficient electrical service size, its risks, and how to address the issue effectively.

Electrical service size refers to the total electrical capacity provided by your service panel, measured in amperes (amps). Common residential service sizes include:

• 60 Amps: Found in older homes, often inadequate for modern demands.

• 100 Amps: Suitable for smaller homes with minimal appliances.

• 200 Amps: The standard for most modern homes.

• 400 Amps: Typically reserved for large homes or those with heavy power usage.

1. Frequent Tripped Breakers or Blown Fuses

Overloaded circuits are a common sign of insufficient service capacity.

2. Dimming or Flickering Lights

Lights that flicker when appliances are in use may indicate your system is struggling to distribute power effectively.

3. Limited Outlet Availability

Reliance on power strips or extension cords suggests your panel lacks the capacity to add more circuits.

4. Inability to Add New Appliances

Modern appliances, such as electric dryers, HVAC systems, or EV chargers, require substantial power. If adding new devices consistently overloads circuits, your service size may be inadequate.

5. Outdated Panel

Older panels with 60-amp service or fuse boxes are often underpowered for contemporary electrical needs.

• Overloaded Circuits: Repeated overloads can damage wiring and increase the risk of electrical fires.

• Limited Functionality: Inadequate service restricts your ability to power modern appliances or expand your home’s electrical system.

• Safety Hazards: Undersized panels and outdated wiring are more prone to overheating and electrical faults.

• Reduced Home Value: An outdated electrical system can deter potential buyers or fail inspection during a sale.

1. Assess Your Power Needs

• Calculate the total wattage of your household’s appliances and devices.

• Consider future needs, such as adding an electric vehicle charger or upgrading HVAC systems.

2. Upgrade Your Electrical Service Panel

• Work with a licensed electrician to upgrade your service to 200 amps or higher, depending on your household’s needs.

• Ensure your utility provider can support the increased capacity.

3. Install Subpanels

• If a full upgrade isn’t feasible, consider adding subpanels to handle power distribution in specific areas of your home.

4. Upgrade Wiring and Outlets

• Ensure your home’s internal wiring can handle the increased load. Upgrade old wiring and add grounded outlets where necessary.

5. Conduct a Professional Inspection

• A licensed electrician can evaluate your current service size, wiring, and overall system to recommend the best course of action.

• Plan for Expansion: When upgrading, choose a service size that accommodates future appliances, home additions, or energy-intensive devices.

• Use Energy-Efficient Appliances: Reduce overall demand by opting for appliances with ENERGY STAR certification.

• Schedule Regular Inspections: Periodic electrical system evaluations can identify issues before they become major problems.

An inadequate electrical service size can hinder your home’s functionality, pose safety risks, and limit your ability to modernize. Recognizing the signs of insufficient capacity and upgrading your service panel not only improves convenience but also enhances safety and long-term value. If you suspect your service size is inadequate, consult a licensed electrician to ensure your home’s electrical system can meet your current and future needs.
