Ensure NEC 220.87 Compliance with Effective Load Recording and Analysis
This white paper details the requirements and best practices for recording electrical load data to comply with NEC 220.87 during facility expansions. It outlines the minimum data needed, recommended monitoring setups, and additional analysis for transformer loading, voltage regulation, and harmonics. The guidance enables accurate assessment of existing loads, supports safe system upgrades, and helps prevent future power quality issues.
Key topics include:
- Introduction to NEC 220.87 Compliance
- NEC 220.87 Requirements
- Gathering the Data
- Analyzing the Data
- Going Further: Transformer Loading, Voltage, and Harmonics
Why utilities should care:
Accurate load recording and analysis support safe system upgrades, optimize asset utilization, and help prevent overloads or power quality issues during customer expansions. Proactive compliance with NEC 220.87 reduces operational risks and ensures reliable service delivery.
