3. Ensure the enclosure is level and plumb.

4.3 Wiring Connections

5. Ensure all connections are tight and secure.

5. Operation

Operating the Eaton 150A Main Breaker Load Center involves managing the main breaker and individual branch circuit breakers.

5.1 Main Breaker Operation

• To turn power ON to the entire load center, push the main breaker handle firmly to the 'ON' position.
• To turn power OFF to the entire load center, push the main breaker handle firmly to the 'OFF' position.

5.2 Branch Circuit Breaker Operation

• Individual branch circuit breakers control power to specific circuits.
• To turn a circuit ON, push the breaker handle to the 'ON' position.
• To turn a circuit OFF, push the breaker handle to the 'OFF' position.
• If a breaker trips (moves to a middle or 'OFF' position), it indicates an overload or short circuit. To reset, first move the handle fully to 'OFF', then to 'ON'. If it trips again, investigate the cause of the fault.

6. Maintenance

Regular maintenance helps ensure the longevity and safe operation of your Eaton Load Center. Always disconnect power before performing any maintenance.

• Annual Inspection: Have a qualified electrician inspect the load center annually for loose connections, signs of overheating, corrosion, or damage.
• Cleaning: Keep the area around the load center clear of obstructions. If necessary, gently clean the exterior with a dry cloth. Do not use liquids or abrasive cleaners.
• Tighten Connections: Periodically, an electrician should check and tighten all electrical connections to prevent arcing and overheating.

7. Troubleshooting

This section addresses common issues you might encounter with your load center.

7.1 Circuit Breaker Trips Repeatedly

• Cause: Overload on the circuit, short circuit, or ground fault.
• Solution: Disconnect some appliances or devices from the circuit. If the breaker still trips, there may be a short circuit or ground fault in the wiring or an appliance. Consult a qualified electrician.

7.2 No Power to Entire House/Area

• Cause: Main breaker tripped, power outage from utility.
• Solution: Check the main breaker in the load center. If tripped, reset it (OFF then ON). If it immediately trips again, contact an electrician. Check with your utility company for local power outages.

7.3 Flickering Lights

• Cause: Loose connection, overloaded circuit, or utility issue.
• Solution: Check for loose connections at outlets or switches. Reduce load on the circuit. If the problem persists, contact an electrician or your utility provider.
