Your Home Electrical System Explained
Understanding the basics of your home's electrical system helps you stay safe and communicate effectively with electricians. Here's a homeowner-friendly guide to how electricity flows through your home.
The Service Entrance
Electricity enters your home through the service entrance, where the utility's power lines connect to your property. This is typically a high voltage connection (240V) that's split into circuits for different uses.
The Main Panel
Your main electrical panel (breaker box) distributes power throughout your home. It contains circuit breakers that protect against overloads. Know where your panel is and how to shut off the main breaker in emergencies.
Branch Circuits
Branch circuits carry electricity from the panel to outlets, lights, and appliances. Most outlets are on 15 or 20-amp circuits, while large appliances like AC units, dryers, and ovens need dedicated high-amp circuits.
Grounding and Safety
Proper grounding protects against electrical shock by providing a safe path for fault currents. GFCI outlets in wet areas and AFCI breakers for bedrooms provide additional protection.
When to Call an Electrician
While understanding your system is helpful, electrical work should be left to licensed professionals. Call an electrician if you notice flickering lights, warm outlets, burning smells, or frequent breaker trips. These can indicate serious problems requiring expert diagnosis.
