Low Voltage/Voltage Drop , This may cause equipment not to function properly and in some cases fail all together, Component/Equipment malfunction failure, Due to many possible causes, this may fail, or an individual component within this, Operation of overload or fault current devices , If too many pieces of equipment are connected to an otherwise healthy circuit this may cause these devices to operate, Arcing, If a connection is loose it may not break entirely but instead produce this. This can result in excessive voltage drop or a fire., High Resistance- Loose connection, Could cause serious voltage drop and excessive heat , Transient Voltages - Lightning Strike, Can cause severe damage to the installation and components. Even the wiring itself could be burned out. , Excessive Current - Overload  , Possibly caused by the consumer connecting too much equipment to the circuit, or a machine being subjected to excessive mechanical loading, Insulation Failure - Deterioration, Can cause current to leak either to adjoining conductors or earth. Can cause localised heat and eventually overcurrent, Mechanical Damage , An example being struck by a forklift truck , Short Circuit, When there is a direct connection between live conductors (Live-earth/Live-Neutral/Live-Live), Earth Fault, A high fault current flowing, Open Circuit, The circuit is broken in some way and no current will flow , Signal Fault , When something is controlled by another piece of equipment such as a PLC and it doesn't do its job.
