What is Pole Loading Analysis?

What is Pole Loading Analysis? For Utility Engineers, Standards, Design, Joint-Use and Operations Teams.

Every overhead pole on your distribution network is subject to forces – wind, ice, wire tension, equipment weight, and the cumulative load of every attachment added over decades. Pole loading analysis (PLA) is how you determine whether a pole can safely carry what’s being asked of it, and whether it meets the structural requirements set by the National Electrical Safety Code (NESC).

But for many professionals, PLA remains an opaque, manual process – or one that’s inconsistently applied across crews, contractors, and joint-use partners.

This free educational webinar cuts through the complexity. In 60 minutes, IKE experts will walk you through the fundamentals of pole loading analysis from the ground up: what the NESC requires, how structural calculations actually work, and what separates a defensible result from one that creates risk.

What We’ll Cover

• NESC Foundations What the National Electrical Safety Code governs, how it’s structured, and which sections affect your overhead design work.
• Clearance Requirements How to determine vertical clearance requirements for conductors over roads, rail, waterways, and other infrastructure. We’ll walk through NESC Table 232-1, the largest final sag condition, and the joint-use clearances that apply in the Communication Worker Safety Zone.
• Pole Loading Fundamentals What a load actually is, the difference between transverse, vertical, and longitudinal forces, and how those forces create bending moments at the groundline. We’ll walk through real examples showing how adding a single cable attachment can increase pole utilization by 15% or more.
• Strength and Loading Under NESC 250B, 250C, and 250D The loading districts, extreme wind, and extreme ice-with-concurrent-wind requirements that govern structural design – and how load factors and strength factors determine whether a pole passes or fails.
• Joint-Use Considerations How attachment requests, make-ready, and joint-use design work interact with NESC requirements. Common mistakes in clearance measurement, separation at the pole versus along the span, and the line-of-sight requirement for spans over 150 feet.
• What Good PLA Practice Looks Like From standardized field data collection to shared component databases to documented, traceable calculation methods – what separates analysis that holds up under regulatory scrutiny from analysis that creates liability.
