TL;DR
A load management device is a hardware controller that monitors a panel's real-time draw and throttles or pauses an EV charger so the combined load never exceeds the service rating. Examples include current-transformer modules mounted at the main breaker and chargers with built-in power sharing for two vehicles on one circuit.
What it means
A load management device is a hardware controller that monitors a panel's real-time draw and throttles or pauses an EV charger so the combined load never exceeds the service rating. Examples include current-transformer modules mounted at the main breaker and chargers with built-in power sharing for two vehicles on one circuit. NEC 625.42 allows a feeder or service calculation to use the device's programmed maximum instead of the charger's full nameplate, which is how many 100-amp homes add 240-volt charging without a service upgrade.
