Fuse/Breaker Keys

The

ElectriCalc Pro has special keys

that automatically calculate the Amp
ratings of the following over-current
protection devices: Dual Element Fuses
(Time Delay), Single Element Fuses
(Non-Time Delay), Instantaneous Trip
Breakers (Type 1), Inverse Time
Breakers (Type 2), and Overload
Protection Devices.

These fuse and circuit breaker sizes
are derived using the “Percent of Full-
Load Current” multipliers listed in NEC
Table 430-52.

You can also calculate the full Voltage
starter size for non-plugging and non-
jogging duty motors based on phase,
Voltage, motor HP and NEMA table
specifications.

If a parameter is missing or invalid, the
calculator will display “nonE.”
