"Leo, calculate the maximum demand. We need to size the main service and the transformer without overspending or blowing a fuse." The Concept: Probable vs. Possible
The ratio of the maximum demand to the total connected load. How to Calculate Maximum Demand: A Step-by-Step Approach maximum demand calculation
Electricians typically use standardized tables provided by regulatory bodies (like the NEC in the US or AS/NZS 3000) that dictate exactly what percentage of each load type must be included in the calculation. Real-World Example In a small home, the calculation might look like this: "Leo, calculate the maximum demand
In the early days of electrical engineering, power systems were designed using simple arithmetic. If a factory had ten motors, each rated at 100 kilowatts, the engineer assumed the demand was 1,000 kilowatts (10 x 100). This is the "Connected Load."
