What is the Circuit Breaker?

Before getting into testing procedures, let's establish a foundational understanding of what a circuit breaker is and how it functions.

The circuit breaker is a switch-like device installed in your electrical panel that automatically interrupts electrical flow when it detects an electrical issue, such as an overload or short circuit. This interruption prevents excessive electrical current from flowing through the electrical system, thereby protecting your home from electrical hazards such as fires or equipment damage.

Why Test the Electrical Panel?

A malfunctioning or broken circuit breaker poses serious risks, including the potential for electrical overloads that can damage appliances, devices, and wiring, or even lead to electrical fires.

Regularly testing your electrical panel is crucial to ensure it is functioning correctly and providing the necessary protection for your home or business.

While annual electrical inspections by certified professionals are recommended, homeowners and business owners should also be proactive in testing their circuit breakers periodically.

What is a Multimeter?

A multimeter is a versatile tool for electrical testing and troubleshooting. It combines several functions in one device: measuring voltage, current, and resistance.
