Changing a circuit breaker is as easy as one, two, three, four. That's right. When working with electricity, safety should always be the primary concern. Assemble any tools that may be necessary and carefully change the breaker. Let's begin.
Turn off the power to the electrical panel. Even though the main breaker is turned off, voltage remains in the panel at the two hot wires that feed the main breaker. Avoid touching these wires. If metal touches one of the metal sections of the wires, a short or arc may occur. Your reaction to either of these may pose more potential for injury than the actual breaker. Be careful!
