Maximum demand is the highest level of electrical load used by an installation during a specific period (usually a 15, 30, or 60-minute interval).

Why is Calculating Maximum Demand Important?

This is the inverse of the diversity factor but preferred by some utilities. maximum demand calculation

A 20 HP motor (15 kW nameplate) may only draw 10 kW under normal load. Use actual operating data or efficiency curves. Basing MD on nameplates leads to gross overestimation. Maximum demand is the highest level of electrical
