VOLTAGE
The maximum allowable voltage variation is ±10% of the
rated voltage on the ice machine model/serial number
plate at start-up (when the electrical load is highest).
The 115/1/60 ice machines are factory pre-wired with an 8'
power cord and NEMA 5-15P-plug configuration.
The 208-230/1/60 and 230/50/1 ice machines are factory
pre-wired with an 8' power cord only, no plug is supplied.
FUSE/CIRCUIT BREAKER
A separate fuse/circuit breaker must be provided for each
ice machine.

TOTAL CIRCUIT AMPACITY
The total circuit ampacity is used to help select the wire size
of the electrical supply.
The wire size (or gauge) is also dependent upon location,
materials used, length of run, etc., so it must be determined
by a qualified electrician.
GROUND FAULT CIRCUIT INTERRUPTER
Ground Fault Circuit Interrupter (GFCI/GFI) protection is a
system that shuts down the electric circuit (opens it) when
it senses an unexpected loss of power, presumably to
ground. Manitowoc does not recommend the use of a GFCI/
GFI circuit protection with our equipment. If code requires
the use of a GFCI/GFI, then you must follow the local code.
The circuit must be dedicated, sized properly, and there
must be a panel GFCI/GFI breaker. We do not recommend
GFCI/GFI outlets, as they are known for more intermittent
nuisance trips than panel breakers.
