Code 22 MAKING AND KEEPING OF RECORDS 22A Keeping of Records by the Owner of an Electrical Installation that Requires Periodic Inspection, Testing and Certification (a) It is the responsibility of the owner of a periodically tested electrical installation referred to in Regulation 20 (see Code 20) to keep the latest test certificates and make available for inspection by the Director. (b) For high voltage fixed installation specified in Regulation 20(1)(c) (see Code 20A), the owner should also make available for inspection a written summary of safety precautions taken for each event of testing and maintenance work carried out on the installation. 22B Making and Keeping of Records by a Registered Electrical Contractor (a) It is the responsibility of a registered electrical contractor to make and keep proper records on all electrical works carried out by him and his employees for the lesser of 5 years or the time since his registration as an electrical contractor. (b) The registered electrical contractor should also ensure that a copy of the records is made available to the owner of the electrical installation upon completion of work. 22C Types of Records (a) For the purpose of Code 22B, a simple single line diagram with symbols to Appendix 8 and simple test results against the lists of items to be inspected and tested detailed in a number of checklists under Code 22D together with test data recorded in the Schedule of Test Results for Electrical Wiring (sample shown in Appendix 13) are acceptable as proper records. (b) For the purpose of Code 22A(b), a record of the permit-to-work together with a maintenance log are acceptable. 22D Checklists (1) Checklists to be used Depending on the varying requirements as indicated in subparagraphs (a) and (b), records showing the results of the items of inspection and testing performed according to the checklists numbered 1 to 4 in Appendix 13 are generally acceptable. 149
