Electrical Service
GENERAL
VOLTAGE
The maximum allowable voltage variation is ±10% of the
rated voltage at ice machine start-up (when the electrical
load is highest).
FUSE/CIRCUIT BREAKER
A separate fuse/circuit breaker must be provided for
each ice machine. Circuit breakers must be H.A.C.R.
rated.
GROUND FAULT CIRCUIT INTERUPTER
Ground Fault Circuit Interupter (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 Ice, Inc. 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.
MINIMUM CIRCUIT AMPACITY
The minimum circuit ampacity is used to help select the
wire size of the electrical supply. (Minimum circuit
ampacity is not the ice machine’s running amp load.)
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.
!
Warning
All wiring must conform to local and national codes.
!
Warning
The ice machine must be grounded in accordance
with national and local electrical codes.
