Load management device
A load management device shares electrical capacity between high-draw appliances so they do not all run at full power simultaneously.
Why it matters
It can prevent the need for a costly electrical panel upgrade by intelligently managing when heavy loads like an EV charger and AC compressor run.
Where people get this wrong
A load management device does not increase total electrical capacity. It schedules demand so existing capacity is not exceeded.
Real-world example
Your panel is at capacity. A load management device lets the EV charger pause briefly when the dryer or AC kicks on, then resumes charging automatically.
Where this hits your build
This matters during rough-in and before drywall. Once walls close, adding or moving wiring becomes expensive. Plan ahead.
Most people do not just struggle with terms. They struggle with the decisions tied to them.
