Wiring With Critical And Non Critical Loads:

Critical loads are generally light loads which are powered under any condition. Non critical loads  are 

loads which can be disconnected to ensure maximum on time for critical loads as well as to extend the 

life expectancy and reliability of the system. The non critical load can be set up as LVD, DD 6 hours or 
DD all night with the same REN configuration detailed earlier.
