Jointing Of Cables

In hazardous areas, cable runs should, ideally, be continuous and without interruption where possible. Joints may only be made using appropriate methods, for example, in an enclosure having a type of explosion protection suitable for the Zone, or by epoxy or compound filled devices, or heat shrink sleeving in accordance with the manufacturer‘s instructions. Whichever method is used, the joints must be mechanically, electrically and environmentally appropriate.

Conductor connections are required to be made by compression connectors, secured screw connectors, welding or brazing. Soldering is permissible if the conductors being connected are held together by suitable mechanical means and then soldered.
