Circuit Breaker

A circuit breaker is an automatic electrical switch designed to protect circuits from damage caused by overload or short circuit. When triggered, it stops the flow of electricity to prevent fires and equipment damage.

How It Works: 1. Electricity flows through the breaker normally 2. If current exceeds safe levels, breaker detects it 3. Breaker "trips" and cuts power to the circuit 4. Circuit remains off until manually reset

Types of Circuit Breakers:

Standard Breakers:

• Single-pole: 15-20 amps, 120V circuits
• Double-pole: 20-60 amps, 240V circuits (AC, dryer, range)

  GFCI Breakers:

• Protect against ground faults
• Required for bathrooms, kitchens, outdoors
• Have "test" and "reset" buttons

  AFCI Breakers:

• Detect arc faults (sparking)
• Required for bedrooms in newer homes
• Prevent electrical fires

  Why Breakers Trip:

• Overload: Too many devices on one circuit
• Short circuit: Hot wire touches neutral or ground
• Ground fault: Current flows where it shouldn't

  When a Breaker Trips:

1. Unplug devices on that circuit 2. Switch breaker fully OFF, then ON 3. If it trips again, call an electrician

Never Do This:

• Don't use a breaker larger than the circuit is rated for
• Don't repeatedly reset a tripping breaker
• Don't ignore frequently tripping breakers
• Don't tape a breaker in the "on" position
