Dear Khun Wijittra,
Dear,
Have a look for the proposed cable and cable route. I have no technical concern to implement. Just to make sure no cable spike from transformer till main breaker.
The cable shall have test report per attached specification.
1. Megger test per standard ELC-SU-2469-E section 4.5 with criteria of pass or fail per 4.6, 4.7
2. Inspect per ELC-SU-4744-D section 7.2 and inspect for
a. 8.1 Conduit System
b. 8.2 Cable Tray and Cable Support System
c. 8.3 Wire and Cable
3. Complete the test record per ELC-DS-4744 page 1 to page 5.
If have additional support please let me know.
Rgds,
