NOTE 1: Furnas intermediate sizes between
NEMA starter sizes apply where (1) is shown in
tables, size 1.75 replacing 2, 2.5 replacing 3, 3.5
replacing 4, and 4.5 replacing 5. Heaters were
selected from Catalog 294, table 332 and table
632 (starter size 00, size B). Size 4 starters are
heater type 4 (JG). Starters using these heater
tables include classes 14, 17 and 18 (inNOVA),
classes 36 and 37 (reduced voltage), and classes
87, 88 and 89 (pump and motor control centers).
Overload relay adjustments should be set no
higher than 100% unless necessary to stop
nuisance tripping with measured amps in all lines
below nameplate maximum. Heater selections for
class 16 starters (Magnetic Defi nite Purpose) will
be furnished upon request.
