Upgrade Your Circuit Breaker and Save
Electricity and safety must go hand-in-hand. Properly installed circuit breakers and up-to-code wiring drastically reduce the risk of electrical fires and hazards.
Cost savings also come into play. An optimized electrical system means your appliances and lights run more efficiently, putting real savings back in your pocket each month.

What Are Circuit Breakers and How Do They Work?
Circuit breakers are a vital part of any modern electrical system. They protect your wiring from damage and your home from electrical fires, which can be caused by issues such as:
- Short Circuits: Irregular connections between currents that can lead to dangerous conditions.
- Overcurrents: Electrical currents that are too large, which can also lead to dangerous conditions.
When the circuit breaker detects irregularities, it cuts off the current. This prevents fires, as well as damage to your wiring and appliances.

Circuit Breaker Replacement
Our team is proud to offer circuit breaker replacement and upgrades to our neighbors in Northern California. Here’s how the process works:
- We will provide an in-home inspection.
This allows us to determine if a circuit breaker replacement is warranted. In some instances, a panel replacement or rewiring will do. - We’ll provide you with an up-front estimate.
We’re honest and transparent with our pricing. We’ll never charge you for something you don’t need—no surprise fees. - We’ll complete the installation to the highest standards.
Our electricians stick to the National Electrical Code (NEC), which is the United States standard for the safe installation and operation of electrical wiring and appliances.
What Are the Signs I Need My Circuit Breaker Replaced?
Circuit breakers can be expected to last between 30 to 40 years. While they have a relatively long life span, they eventually need to be replaced. Additionally, older models may not be able to handle modern electrical demands. That’s why it’s essential to schedule an electrical inspection whenever you move into a new home.
Think you might need a new circuit breaker? Besides age, here are a couple of indicators:
If your breaker shows signs of scorching or emits a burning smell, this is a serious red flag. It likely means the wiring is overheating or melting from overcurrent. This is a potential fire hazard—shut off your main power and call Ongaro & Sons.
Fuse Box to Circuit Breaker Upgrades
Were you aware that electricians stopped installing fuse boxes in new homes built after 1960? Even if they have been modified, fuse boxes aren’t designed to meet today’s energy demands.
If your older home still has a fuse box, get it replaced. Our team of electricians can help you upgrade to a modern circuit breaker that meets your home energy needs.
