⚡ OPENING HOOK

Smart systems can control power...

But the NEC controls the safety behind them. ⚠️

🧠 CORE IDEA

⚡ An Energy Management System (EMS) is used to monitor and control electrical loads to improve efficiency.

It can:

⚡ Monitor electrical loads
⚡ Control utilization equipment
⚡ Manage energy storage systems
⚡ Reduce peak demand

But efficiency is never allowed to compromise safety.

⚡ CODE CONNECTION

NEC Article 130 sets the rules for when EMS equipment is allowed—and when it becomes a Power Control System (PCS).

Key requirement:

✔ EMS equipment must be listed

If it is used to prevent overload conditions:

✔ It must also be listed and labeled as a Power Control System (PCS)

📌 NEC 130.2

📌 CORE TAKEAWAY

⚡ EMS = monitoring and load control for efficiency

⚡ PCS = EMS that actively prevents overloads (strict listing rules apply)

⚡ All systems must be properly listed for their function

⚡ FINAL LINE

Smart systems don’t replace the Code...

They have to follow it. ⚡
