On completion of the installation the flameproof threaded joint 7.2. Cable Selection and Connections should be inspected to ensure that they are clean and that they have not been damaged during installation. When selecting the cable size, consideration must be given to the input current that each unit draws (see table 1), the Flameproof threaded joints are not intended to be repaired. - Page 5 External earthing connections should be made to the M4 NEC / CEC Requirements Only earth stud, using a ring crimp terminal to secure the earth conductor to the earth stud.
