Electrical Panels & Panel Upgrades
Keep Your Home Powered with a Reliable Control Center
Your electrical panel is the nerve center of your home's power system. All the electricity entering your home is distributed through this essential unit. When your panel starts to show signs of age or damage, it isn’t something you should attempt to fix on your own. At Lenn Johnson Electric, our licensed professionals are here to inspect, repair, and upgrade your electrical panel—ensuring safe and efficient power flow throughout your home.
What Is an Electrical Panel?
An electrical panel, often referred to as a breaker box, manages and distributes the electricity that comes from your utility provider to various circuits in your home. When you open the panel, you will see rows of switches known as breakers. Each breaker controls the electrical flow to a different part of your home, safeguarding your circuits by automatically cutting off power in case of an overload.
Electrical Panels Versus Fuse Boxes
Homes built before the 1960s often have fuse boxes instead of modern electrical panels. Unlike breaker panels, fuse boxes use colored plugs that fuse when overloaded. These older systems lack the advanced safety features and higher amperage capacity of modern panels. If your home has a fuse box, it’s an excellent candidate for an upgrade to a reliable, modern electrical panel.
When to Consider a Panel Repair or Upgrade
Not every electrical glitch requires a complete panel upgrade, but some warning signs should not be ignored:
Frequent Breaker Trips: Constantly tripping breakers can indicate that your panel is overburdened.
Flickering or Dimming Lights: An inconsistent flow of power might suggest panel or wiring issues.
Buzzing or Humming Sounds: Odd noises from your panel can be a sign of internal malfunctions.
Unusual Heat or Burn Marks: Warm panels or scorch marks near outlets or breakers signal potential fire hazards.
Outdated Equipment: If you still have a fuse box or an older panel that no longer meets your home’s power needs, it’s time for an upgrade.
When you notice these signs, contact us. Our experienced electricians will diagnose the situation and recommend whether a repair, retrofit, or full replacement is the best solution.
