that they are capable of withstanding the highest thermal and dynamic stresses that may occur at the place of installation of Switch Board Cabinet.

7.8.4 During prototype test continuity of all live components shall be checked as per wiring diagram attached with specification.



7.8.5 For lids, doors, cover plates etc. the usual metal screwed connections and metal hinges are considered sufficient to ensure continuity provided that no electrical equipment is attached to them.

7.9 Verification for effectiveness of protective circuits: 7.9.1 Following interlocking shall be checked during this test;

(i) Interfacing of HOG contactors with fire & smoke detection system (ii) Interlocking of HOG contactors with bus coupler contactor K02 (iii) Interlocking between feeder contactors K04 & K05 and K06 & K07

7.9.2 Following component shall be tested on test bench; (i) Overload and Earth leakage protection relays (ii) All power contactors pick up and drop out voltage. (iii) Minimum 3 MCBs of each rating for different voltage grades. (iv) DC-DC converter

These tests shall be carried out during type test and routine test. 7.9.3 It shall be verified that the different exposed conductive parts of the assembly are

effectively connected to the protective circuit in accordance with some requirements. A protective circuit in an assembly consists of either a separate protective conductor or the conductive structural parts or both. It provides the following- (i) Protection against the consequences of faults within the assembly. (ii) Protections against the consequences of faults in external circuits supplied

through the assembly Detailed interlocking and protection scheme will be submitted by manufacturer and will be discussed in design stage.

7.10 Temperature rise test: Temperature rise test of the Switch Board Cabinet shall be carried out as per clause no. 8.2.1 of IS 8623 Pt -1. The reading at various points of switchgears, conductors / & insulators, fuses, bus bar, power cables, panel body, panel doors, handles etc. shall be measured at an interval of 30 minutes till the temperature gets stabilized. The value of SBC internal air average temperature should not be more than 70°C w.r.t. 50°C environmental temperature. The firm shall submit the test scheme for temperature rise test in advance to RDSO as per electrical circuit wiring diagram given with this specification and get it approved.

7.11 Shock and Vibration test: Shock & vibration test of complete SBC shall be conducted as per category 1, class B as per IEC 61373 from any NABL/NABCB accredited agency.
