In your everyday life, you likely only think about the surface level of your electrical system. This fundamental aspect of the system lets you light rooms, heat water for bathing, control your indoor temperature, and cook on an electric stove top.

Behind your power outlets and light switches, your electrical wiring creates a network that conducts energy throughout your home wherever it is needed to flip on a certain light or heat up a stove burner.

However, while your electrical system is technically all interconnected, the network is broken up into smaller sections called circuits. Circuits ensure that even with all the lights on, your range still gets enough consistent power for you to predict how a burner will operate as you cook dinner.

Your circuits are all connected to an electrical panel, sometimes called a breaker box. Each circuit has a designated switch in the panel, known as a breaker. While many electrical issues affect the entire system, others simply impact a single circuit breaker.

In this blog, we list seven indicators that you may need to upgrade a circuit breaker.
