1. Poor contact: The connection terminal or plug of the power socket has poor contact with the socket. When household appliances are inserted, due to the unstable contact point, there will be current
Through this, a spark is thus generated.
2. Damaged socket or plug: The spring blades of the socket or plug are worn or damaged, resulting in poor contact and causing sparks when the plug is inserted or removed.
Iii. Aging or Damaged wires: If the wires age and the insulation layer is damaged, it will cause a short circuit in the wires, thereby generating sparks.
Four. Excessive current: When the power of an electrical appliance is too high, the current at the moment of insertion or removal is large, generating an electric arc.
V. Neutral wire issue: The neutral wire connector was not properly connected, resulting in sparks and causing the neutral wire to burn.
Six. Fuse blowout: The fuse blows due to overload or other reasons, causing the current in the circuit not to pass through the normal circuit path and thus generating sparks.
Seven. Short circuit in the circuit: When a short circuit occurs between the wires in the circuit, the current cannot flow normally, resulting in the generation of sparks.
