Labeling the Electrical Panel

Understanding the Labeling System

Properly labeling your electrical panel is essential for quickly identifying and controlling the various circuits in your home. Start by locating the main breaker or disconnect switch, which will shut off power to the entire house. Typically, the main breaker is larger than the others and may be labeled as such. Each circuit breaker or fuse should also be marked with its corresponding location or purpose, such as “kitchen outlets” or “living room lights.”

Determining the Function of Each Circuit

To determine the function of each circuit, you can use a process of trial and error. Turn off one breaker or remove one fuse at a time and observe which area of your home loses power. You can then label the breaker or fuse box accordingly. It may be helpful to have another person assist you by informing you when the power goes out in specific areas.
