NEC 130 LIMITATIONS ⚡
Critical Loads Always Protected

⚡ OPENING HOOK
Some loads are never optional…
Even for an Energy Management System. ⚠️

🧠 CORE IDEA
⚡ An EMS is designed to manage and reduce electrical demand, but it has strict boundaries when it comes to essential systems.

Certain loads are required to remain operational at all times and cannot be disconnected or shed by EMS control.

EMS cannot disconnect:
🛗 Elevators
🪜 Escalators
♿ Stairway lift chairs

It also cannot disconnect:
💨 Hazardous location ventilation
☣️ Hazardous gas exhaust systems
💡 Emergency lighting
🏥 Essential healthcare systems

And EMS control must never create a condition that overloads a branch circuit, feeder, or service.

⚡ CODE CONNECTION
NEC Article 130 protects life-safety and critical operation systems from being interrupted by energy management functions.

Even if load reduction is active elsewhere in the system, these loads remain continuously available because they are required for occupant safety and building operation.

📌 CORE TAKEAWAY
⚡ EMS cannot disconnect life-safety or critical loads
⚡ Essential systems always stay online
⚡ Load management stops where safety begins

⚡ FINAL LINE
If it’s required to protect people…
It stays on. ⚡
