EDR Fuse Selective Coordination Calculator

The primary goal of Selective Coordination is to isolate the circuit that is being overloaded or has experienced a short-circuit condition. At the same time, it is desirable to keep the remainder of the system operational such that other loads are not affected. Proper Selective Coordination of fuses avoids unintended blackouts.

This program allows the user to quickly determine either the required line side fuse or the required downstream or load side fuse. The program will also allow Selective Coordination when both fuses are known.

Like other EDR calculation modules this module contains extensive Help files for program use, engineering applications advice, NEC code requirements and paths to other information resources. The module also contains calculation/project documentation aids.
