Flexibility

A cable should be immediately rejected if it is getting cracks while bending. The insulation material should be highly flexible.

Cables are used for both indoor and outdoor purpose depending upon the requirement. A trusted and experienced crew should be hired to install cables properly so that no cuts and cracks left behind.

One must wear safety glasses and protective clothing before installing cables and connecting them to the power source. The flow of current in a cable should be tested with a voltage tester before connecting it to an electric appliance.
