⚡ OPENING HOOK
PCS settings aren’t just programming numbers…
They directly affect load calculations. ⚠️

🧠 CORE IDEA
⚡ Every controlled conductor, load, or source in a Power Control System has a defined control setting.

These settings determine how the system manages electrical demand and prevents overload conditions.

PCS control settings:
⚡ Are set in amperes
⚡ Are treated as continuous loads
⚡ Can be used in load calculations

🧠 CORE IDEA
⚡ PCS settings are not adjustable by anyone on site.

They are restricted and must only be changed by qualified persons in accordance with the equipment listing requirements.

⚡ CODE CONNECTION
NEC Article 130 requires PCS control settings to be:
✔ Locked/protected per listing
✔ Restricted to qualified persons
✔ Used as part of the load calculation method when applicable

These settings are part of the system design—not field adjustments.

📌 CORE TAKEAWAY
⚡ PCS settings directly impact load calculations
⚡ They are treated as continuous load values
⚡ Only qualified persons can adjust them

⚡ FINAL LINE
If you change the setting…
You change the load calculation. ⚡
