- Rodent Control: Implement measures to prevent rodent infestations.
Overloaded Circuits:
- Description: An overloaded circuit occurs when the total electrical load exceeds the circuit’s capacity.
- Causes:
- Multiple High-Power Appliances: Connecting too many high-wattage appliances to a single circuit.
- Inadequate Circuit Capacity: Using circuits that are not rated for the AC unit’s power requirements.
- Symptoms:
- Frequent Circuit Breaker Trips: The circuit breaker trips repeatedly when the AC unit is running.
