Transformer-Rectifier Procedures Groundbed Ensure that all relevant site conditions and working practices are observed. If necessary obtain a work permit as required by the site. Locate the site and clear any undergrowth. Check for buried services with a pipe/cable locator. Excavate to the required depth, and excavate trench for cable as required. Arrange the anodes and main cable ready for installation. Connect the anodes and the main cable according to the specification. Actual connections are usually made by line tap (split bolt) and sealed with an appropriate splice kit filled with resin. Ensure sufficient time is allowed for the resin to set. Allow sufficient cable to enable either termination in a junction box near to the trench or at the transformer. This will be specified according to the design of the system. Test the continuity of the cables. Use half the carbonaceous backfill and line the bottom of the trench. Place the anodes and main cable on the carbonaceous backfill. Use the remainder of the carbonaceous backfill to cover the anodes. Backfill the trench and re-instate the ground. Excess spoil to be removed from site. Terminate the cables appropriately. DC Cables

Cable connections to the pipe should be made as in 5.1.1. Positive or groundbed cables should be treated with great care to prevent any damage to the insulation. Buried cables should lie at a depth that will protect them from disturbance by ploughing or other excavations. Cable tiles or cable warning tape should be used to warn of the presence of the cable during any subsequent excavation. The specification may call for above ground installation of cables. In this case, the cable should be installed as required in the specification. AC Cables Generally AC mains voltage cables will be provided by the electricity supplier and terminated by them or by a qualified electrician. If it is necessary to install mains voltage cables then the requirements of BS7671 should be observed and advice sought from a qualified person.
