8. Lighting Design Calculations

Demand Factors:

You rarely run every light and appliance at once. Engineers apply "demand factors" from codes like NEC Article 220 to adjust the total load to a realistic peak level. 2. Sizing Service & Feeders Formulas are clearly laid out with consistent units

3. Regulatory context & standards (2–3 pages)

Formulas are clearly laid out with consistent units and notation.
Includes worked examples for residential, commercial, and light industrial scenarios.
Quick-reference tables (e.g., cable ampacity, correction factors, conduit fill) save time.
No fluff—direct and to the point, which is great for on-site or deadline-driven work.

Site data: supply voltage, source impedance, available fault current, service type (TN/TT/IT), number of phases, neutral configuration.
Design assumptions: diversity factors, simultaneity, occupancy types, lighting power densities (LPD), equipment ratings, environmental corrections (temperature, grouping).
How to document assumptions clearly (table template).
