PERENCANAAN INSTALASI LISTRIK GEDUNG WAREHOUSE PT. XYZ SEMARANG JAWA TENGAH

Abstract

Warehouse Building PT. XYZ at Semarang Central Java is a building place for keeping logistics owned by the company with a large area. There is also buildings' support in it so that required system installation suitable electricity with applicable standards such as PUIL 2011 and other standards in the field of electricity. The main electricity supply uses a source from PLN, and the generator is set as a backup source when electricity from PLN is dead. Plan installation at PT.

With more formerly collected load data equipment electricity at PT. XYZ Semarang and classification distribution system split panel installation, SDP panel, and LVMDP panel. The total load installed on the PT.
