It seems likely that your power socket (or the wiring in general or some other connected item on that circuit) is causing an intermittent short circuit, which could be simply connections or wires that are out of sight, touching earthed metalwork due to the item being insecure or wobbly or worn. I would inspect closely, as soon as.


Yes, but "an excess of current" can also be caused by a loose connection. The loose connection causesa voltage drop, which results in an increase of amperage...


Doug is correct. Sorry but back to physics classes I'm afraid [Linked Image]

A bad/intermittent connection provides an increase in circuit resistance which does cause a voltage drop at the connection point, but by the same token a reduction in circuit current. I = E/R
