Moisture shall be excluded from the joint during the splicing operation and the work shall be done in dry weather or under shelter. All materials and tools involved in the splicing process shall be kept dry. One of the following methods shall be used for making a watertight and electrically insulated splice: Method No. 1. The outer covering and insulation of the conductor shall be removed from each conductor for a minimum length necessary for the use of a pressure release crimping tool. The conductor ends shall be bared and joined with a seamless, solderless-type sleeve connector of the same AWG size as the conductor being spliced, using a pressure-release crimping tool designed for the size connector being used. After crimping, the sleeve connector shall maintain proper contact with both conductors around the circumference of the splice and along the length of the sleeve. The portion of each conductor where insulation has been removed, and the sleeve connector, shall be reinsulated with a coat of fast-drying sealing agent of electrical grade, a tight wrap of overlapping layers of rubber tape, a second coat of fast-drying sealing agent of electrical grade, and then a tight wrap of overlapping layers of polyvinylchloride tape. The sealing agent and tape shall extend at least 1 inch onto the undisturbed insulation of each conductor. Layers of tape shall be applied on the splice to equal 1.5 times the thickness of the original insulation. 680-3.17 349 Section 600 STANDARD SPECIFICATIONS (USC) January 1, 2026 VOLUME 3 Rejacketing the cable shall be accomplished in a similar manner as described in Method No. 1 except that the sealing agent and tape shall extend at least 4 inches onto the undisturbed outer covering of each cable. Individual splices in each conductor shall be staggered to minimize the outside diameter of the spliced cable. Method No. 2. All the requirements for splicing specified in Method No. l shall apply except that the completed splice, including sleeve connector and the portion of each conductor where the insulation has been removed, shall be reinsulated and the cable rejacketed by using an acceptable mold poured full of a two-component, electrical-insulating resin. The resin shall produce satisfactory pouring consistency without applying external heat. The resin shall be mixed and applied per the manufacturer’s directions. Method No. 3. This method shall be accomplished by use of a weatherproof or waterproof splice connector/splice box. Splicing shall be accomplished by following the splice connector/splice box manufacturer’s instructions. This method shall be considered as the preferred method, as it requires less installation time and material, compared to the other two methods listed above.
