Firstly, it is important to isolate the installation from the mains supply before attempting to check or repair flooded cables. For obvious reasons, the sooner the flood recedes and action is taken the more likely it is that the cables will not be adversely affected. Find out what to do when the wat......

The voltage rating of a cable is the highest voltage that may be continuously applied to a cable construction in compliance with the relevant cable standard or specification.
Voltage rating figures for cables are normally expressed in A.C. RMS. (Alternating Current Root Mean Square) and are wri......

The RoHS is a directive of the European Parliament and the European Union Council that aims to reduce the use of certain dangerous substances commonly used in electric and electronic equipment (EEE).  EU legislation restricts the use of hazardous substances in electrical and electronic equipment and......

A spark test is an inline voltage test used either during cable manufacturing or during a rewinding process. Spark testing is primarily for low voltage insulations and medium voltage non-conducting jacket or sheaths. The test unit generates an electrical cloud around the cable which in high frequenc......
