Here is the correct procedure for joining low voltage cables: a. Selection and safe use of tools and equipment: Only insulated tools specifically designed for electrical work, such as wire strippers, crimping tools, and heat guns (for heat-shrink joints), should be selected. These tools must be in good condition and used according to their intended purpose. Personal Protective Equipment (PPE), including safety glasses and insulated gloves, must be worn to prevent injury from electrical shock or mechanical hazards. b. Manufacturer's specifications for joining cable cores: The manufacturer's instructions for the specific cable jointing kit being used must be strictly followed. This includes precise measurements for stripping insulation, correct crimping techniques for connectors, and proper application of jointing materials (e.g., resin, heat-shrink tubes). Adhering to these specifications ensures the joint maintains the cable's electrical and mechanical integrity. c. Continuity, insulation, and mechanical testing requirements: After joining, the cable must undergo testing. Continuity testing (using a multimeter or continuity tester) verifies that the electrical circuit is complete and there are no open circuits. Insulation resistance testing (using an insulation resistance tester or megohmmeter) checks that the insulation between conductors and to earth is intact and meets minimum resistance values, preventing short circuits and leakage current. Mechanical testing involves visually inspecting the joint for proper sealing and physical integrity, ensuring it can withstand environmental stresses and physical strain.
