Cable Routing Final 3rd

1) A new panel will temporarily draw power from an existing main distribution panel's spare 800A circuit breaker, which is not connected to UPS or generator backup power. 2) Two proposals are presented: install a static UPS to provide 5 minutes of backup power for small outages, or redesign loads and connect some to existing UPS systems after reconfiguring connections from three transformers to improve reliability. 3) Further vendor advice is needed to study disconnecting non-critical loads like chillers from the new panel design.

Temporally this panel will feed from the main distribution panel MDB1 ( TR.

1 2000KVA) from a spare circuit breaker 800A, and as this 800


Amps circuit breaker is not connected to neither UPS nor Generator so the proposals are:
1 ) Install a static UPS with batteries which will keep the line running for a duration for 5 minutes and eliminate small power off only but it
can't grantee operate the line more than this
2 )As - built SLD for three transformers and re-design all loads to allow studying disconnect some not important loads like chillers (vendor
advise is needed) and connect the complete new line to existing UPSs
