An overload protection system includes a panelboard and a load management system (LMS) which is configured to constantly measure the total amount of power being used at the panelboard such that when the total amount of energy measured is at or above a high programmed level, the LMS stops power from being supplied to a load and when the total amount of energy measured is at or below a low programmed level, the LMS allows power to be supplied to the load. The LMS includes a monitoring relay with a “threshold hysteresis” built-in, which means that a threshold current at which an output switches from one state to another state is different depending on whether an input current is increasing or decreasing. The “threshold hysteresis” helps to eliminate noise and ensure that the output switches cleanly between ON and OFF, even if an input current level is fluctuating around a threshold current level.
