Below are just a handful of items we have found in an unsafe condition whilst we have been out Testing and Tagging in Melbourne. We have calculated than on average 8% of items fail on the first round of Testing and Tagging.
This item was found with a cracked safety screw connector. All 3 phase equipment comes with this safety screw, which ensures that the item will have a secure connection so as to not allow the unintentional removal. this also ensures that the connection between plug and outlet are tight and not allow “arching”. If a circuit has enough current and voltage to sustain an arc formed outside of a switching device, the arc can cause damage to equipment such as melting of conductors, destruction of insulation, and fire.
