NEC 120.7(C)(2) EXPLAINED ⚡
DON’T FORGET THE REST OF THE BUILDING

⚡ OPENING HOOK

A PCS doesn’t change everything...

And this is where people get it wrong. ⚠️

🧠 CORE IDEA

⚡ Even when a Power Control System is installed, not all loads are controlled.

NEC 120.7(C)(2) makes it clear:

Noncontrolled loads are still calculated normally.

No reductions.

No substitutions.

No PCS adjustments.

⚡ CODE CONNECTION

NONCONTROLLED LOADS:

❌ Not reduced by PCS
❌ Not replaced by control settings
❌ Not modified by system monitoring

✔ Must be calculated using standard NEC Article 120 rules

The PCS only affects what it actually controls—not the entire electrical system.

🧠 REAL-WORLD EXAMPLE

A typical service may include:

🔌 EV chargers (PCS-controlled)
💡 Lighting
🖥️ Receptacle loads
❄️ HVAC systems

⚡ The PCS may reduce EV charging demand...

But:

💡 Lighting = full calculated load
🖥️ Receptacles = full calculated load
❄️ HVAC = full calculated load

Unless another NEC rule allows adjustment, nothing changes for these loads.

📌 CORE TAKEAWAY

⚡ PCS only affects controlled loads.

⚡ Noncontrolled loads are always calculated using standard NEC rules.

⚡ A PCS is not a system-wide reduction tool.

⚡ FINAL LINE

Just because a PCS is installed...

Doesn’t mean the whole building gets a discount. ⚡
