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

Overload Protection —
♦ First Press
Displays the Overload Amperage requirement
based on the Full-Load Current shown on the
motor nameplate. Multiplies the entered
motor nameplate Full-Load Current
(stored in the
 register) by 115% or
the value you enter.
Conforms to NEC Section 430.32(A)(1) value
of 115%, unless you enter another value. For
example, entering 125  would calculate
Overload protection based on 125% of the
entered Amperage.
