Abstract
The electric service load of a machine having at least one electric heater and at least one electric motor may be managed as follows. Where the electrical service load of the machine exceeds a threshold, which may result from transient in-rush current attendant upon start-up of an electric motor, or where this load is expected to exceed the threshold, at least one of the heaters may be de-energized. The heater may remain de-energized either for a pre-determined period of time or until the electrical service load falls below a further threshold.
