Overtight & Loose Cables
Why are loose cables dangerous?
Loose connections can cause arcing between the cables themselves and metal terminals, resulting in an arc flash. This is where electricity flows or discharges along an unintended path, igniting with particles in the environment. It can result in electrical fires thanks to the incredibly high temperatures produced.
Tightening cables too much can also be dangerous. If the overtightened area causes cables to break, it could leave loose connections at the terminals, causing the same issue.
Circuits for ovens, showers and hobs are the sites of many overloaded cables. Some bathroom fitters or builders install this type of appliance without considering both cable sizes and the total load. If the circuit can’t handle the amount of electricity running through it, the wiring could overheat. It the insulation then starts to melt, it could cause a fire in your property.
