Maximum Demand Calculator Instant

You might use most lights at once, so the factor is high (e.g., 75–100%).

Grab your last 12 utility bills. Find the highest "Demand" value. Compare it to the sum of your connected load. You will likely find you are paying for capacity you rarely use.

If you don't have a power analyzer, use this systematic approach to estimate your MD. maximum demand calculator

The Maximum Demand Calculator consists of three core modules:

| Load | Connected (kW) | Demand Factor | Calculated Demand (kW) | | :--- | :--- | :--- | :--- | | LED Lighting | 10 | 0.90 | 9.0 | | 20 Outlets (PCs) | 10 | 0.40 | 4.0 | | 10 Outlets (Misc) | 5 | 0.20 | 1.0 | | AC Unit (5 HP) | 3.7 | 1.00 | 3.7 | | Water Heater | 4.5 | 0.75 | 3.4 | | | | | 21.1 kW | You might use most lights at once, so the factor is high (e

By accurately calculating demand, you avoid buying oversized cables and switchgear, which can save thousands in material costs.

A Maximum Demand calculator is not just a math exercise; it is a financial planning tool. and your breaker will trip constantly. Over-estimate MD and you will pay thousands extra per year in demand charges, plus overspend on cable and switchgear capacity.
