I plugged in an appliance. It immediately created a loud noise and spark. Had to go to the circuit break to flip the power back on. Was it a current overflow in the cord?

Appliances consume a high inrush current when first switched on, especially if they consist of a powerful motor or a DC power supply of a computer. They charge capacitors as quickly as possible, or to spin up the motor from standstill. If the nominal power is 1 kW or greater, it could trip the circuit breaker if other devices are also drawing power at the same time. Or your appliance could be broken and have short circuited.
