A crackling plug socket indicates electrical arcing, where current struggles to flow due to poor contact, generating heat that can lead to fires. Common causes include loose wiring from heat expansion and vibration, internal high resistance from worn-out sockets, water ingress creating short circuits, or a damaged internal mechanism preventing proper connection. Corrosion from moisture can also lead to bad connections. A crackling socket is a serious issue requiring immediate attention. Switch off the power and contact a qualified electrician to inspect and replace faulty components before further damage occurs. Safety is a priority with electrical faults.
