switchboards. The torque to apply depends on the screw size. Mark each tightened nut using indelible varnish. Carry out the insulation check between each phase or neutral(1) and earth, as described instep 4. NOTE: Once the transformer has been reconnected (star secondary), the phase-earth measurement is the winding resistance. Using a Roto-phase or 3–phase harmonic analyzer (CA8334 or Fluke 434), carry out aphase order check. This is to detect any inversion of the phases or neutral among the four incoming and outgoing connections of the busbar trunking system, with respect to the transformer output.6Protection settings check Check that the upstream circuit breaker protection settings are in accordance with theinstallation drawing specifications and the protection plan of the busbar trunking system.  Carry out compliance checks of the following, in accordance with the installation drawingspecifications:  Imax thermal  In magnetic
