5.2 Electrical Category Privileges: With respect to maintenance of aircraft, certification of maintenance within the electrical category may be made by persons holding the appropriate electrical rating with the following limitations:
 (a) maintenance of components which are supplied as bench tested units, installed in aircraft — limited to inspection, replacement and adjustment of parts normally adjustable or replaceable in service where the subsequent operation may be proved without the use of test equipment additional to that normally used for functional tests on the aircraft;
 (b) maintenance of an electrical system which includes any of the following is excluded unless the licence holder is, or is employed by, the holder of a valid appropriate certificate of approval:
 (i) the disturbing of individual parts of units which are supplied as bench tested units, where subsequent functioning must be proved using test equipment additional to that used for normal functional tests on the aircraft or troubleshooting;
 (ii) maintenance of operational and automatic test equipment (ATE) software;
 (iii) initial installation or subsequent modification of an electrical system.
5.3 Electrical Category — Instrument Category Privileges: Certification of maintenance within the instruments category may be made by persons holding the appropriate electrical rating — limited to maintenance of interwiring, excluding functional tests of instrument systems required after maintenance.
5.4 Electrical Category — Airframe/Engine Categories Privileges: Certification of maintenance within the airframe or engine category may be made by persons holding the appropriate electrical rating, limited to electrical components and wiring.
5.5 Electrical Category — Radio Category Privileges: Certification of maintenance, excluding operational checks, within the radio category may be made by persons holding the appropriate electrical rating as follows:
         (a) on aircraft approved only for V.F.R. operations limited to:
 (i) security of attachment of wiring and components; and
 (ii) replacement of removeable items of equipment of radio systems;
 (b) on aircraft approved for I.F.R. operations — limited to security of attachment of wiring and components.
