[O-Load] — Overload Protection
♦
First Press
Displays the overload amperage re-
quirement based on the full-load cur-
rent shown on the motor nameplate.
Multiplies the entered motor nameplate
full-load current (stored in the [Amps]
registers) 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, en-
tering 125 [O-Load] would calculate
overload protection based on 125% of
the entered amperage. Displays:
AMPS ol.
♦
Second Press
Displays the full-load current percent
multiplier value used to determine the
overload current protection size. Sub-
sequent presses of [O-Load] repeat the
cycle. Displays: %FLC.
[Set] [HPmotor] — Starter Size
Displays the starter size (from NEMA
publication ICS 2-1988 Tables 2-327-1
and 2-327-2) based on the phase, volt-
age, and motor horsepower settings.
Displays: STAR SIZE.
NOTE: Horsepower values not identi-
fied in NEMA tables will cause the cal-
culator to round up to the next larger
starter size in the table.
