1) This may cause equipment not to function properly and in some cases fail all together a) Component/Equipment malfunction failure b) Low Voltage/Voltage Drop c) Insulation Failure - Deterioration d) Transient Voltages - Lightning Strike 2) Due to many possible causes, this may fail, or an individual component within this a) Low Voltage/Voltage Drop b) Transient Voltages - Lightning Strike c) Component/Equipment malfunction failure d) Mechanical Damage 3) If too many pieces of equipment are connected to an otherwise healthy circuit this may cause these devices to operate a) Operation of overload or fault current devices  b) Low Voltage/Voltage Drop c) Excessive Current - Overload   d) Earth Fault 4) If a connection is loose it may not break entirely but instead produce this. This can result in excessive voltage drop or a fire. a) Arcing b) Short Circuit c) Open Circuit d) Mechanical Damage 5) Could cause serious voltage drop and excessive heat  a) Short Circuit b) Signal Fault c) Low Voltage/Voltage Drop d) High Resistance- Loose connection 6) Can cause severe damage to the installation and components. Even the wiring itself could be burned out.  a) Insulation Failure - Deterioration b) Transient Voltages - Lightning Strike c) Operation of overload or fault current devices  d) Signal Fault 7) Possibly caused by the consumer connecting too much equipment to the circuit, or a machine being subjected to excessive mechanical loading a) Excessive Current - Overload   b) Short Circuit c) Mechanical Damage d) High Resistance- Loose connection 8) Can cause current to leak either to adjoining conductors or earth. Can cause localised heat and eventually overcurrent a) Open Circuit b) Operation of overload or fault current devices  c) Signal Fault d) Insulation Failure - Deterioration 9) An example being struck by a forklift truck  a) Mechanical Damage b) Operation of overload or fault current devices  c) Component/Equipment malfunction failure d) Earth Fault 10) When there is a direct connection between live conductors (Live-earth/Live-Neutral/Live-Live) a) Operation of overload or fault current devices  b) Short Circuit c) High Resistance- Loose connection d) Insulation Failure - Deterioration 11) A high fault current flowing a) Earth Fault b) Excessive Current - Overload   c) Mechanical Damage d) Transient Voltages - Lightning Strike 12) The circuit is broken in some way and no current will flow  a) High Resistance- Loose connection b) Open Circuit c) Excessive Current - Overload   d) Transient Voltages - Lightning Strike 13) When something is controlled by another piece of equipment such as a PLC and it doesn't do its job a) Mechanical Damage b) Signal Fault c) Low Voltage/Voltage Drop d) High Resistance- Loose connection
