⚡ OPENING HOOK
A PCS install isn’t finished when it’s wired…
It’s finished when it’s documented correctly. ⚠️

🧠 CORE IDEA
⚡ Article 130 requires full identification and documentation of any Power Control System (PCS) used in a building.

This ensures future electricians and inspectors understand how load management is affecting system operation.

Required markings include:
✔ PCS settings
✔ Managed loads and sources
✔ Qualified person information (commercial systems)
✔ Required warning labels

🧠 CORE IDEA
⚡ Documentation must clearly define how the PCS operates within the electrical system.

This includes:
📄 Monitoring functions
📄 Control equipment details
📄 PCS settings
📄 Single-source or multi-source configuration

If the PCS is NOT within sight of the overcurrent protective device, a directory identifying controlled circuits is required.

⚡ CODE CONNECTION
NEC Article 130 ensures that PCS systems remain identifiable and serviceable throughout the life of the installation.

Without proper labeling and documentation, future load calculations and system servicing can be performed incorrectly or unsafely.

📌 CORE TAKEAWAY
⚡ PCS systems must be clearly marked and documented
⚡ Settings and controlled loads must be identified
⚡ Future maintenance depends on proper labeling

⚡ FINAL LINE
If it isn’t labeled…
It doesn’t exist in the field. ⚡
