Overloaded circuit—unplug devices exceeding its amp rating (usually 15A) or replace with a higher-capacity model.
Yes! Trace the wire with a tone generator and probe or check for voltage drops with a multimeter.
Match the wire gauge (AWG) to the load: 16 AWG: Lights/small electronics (<10A). 14 AWG: Power tools (10–15A). 12 AWG: Heavy-duty equipment (15–20A)
Use a battery and bulb tester: Connect wires to the circuit—if the bulb lights, there’s continuity.
