Max Demand Table -

Setting the maximum demand based strictly on the current rating or thermal trip threshold of the main upstream circuit breaker.

| Row | Circuit Description | Connected Load (W / A) | Diversity / Assessment Factor | Assessed Demand (W / A) | | :--- | :--- | :--- | :--- | :--- | | 1 | Lighting | | | | | 2 | Socket Outlets | | | | | 3 | Fixed Appliances | | | | | 4 | HVAC | | | | | 5 | Motors | | | | | 6 | | | | SUM | | 7 | Voltage (V) | | | _____ V | | 8 | Final Max Demand (Amps) | | | Row 6 ÷ Row 7 | | 9 | Safety Factor / Future Load | | | +25% (typical) | | 10 | Final Required Rating | | | Row 8 + Row 9 |

The specific table you should use depends on your regional standards (like the in Australia/New Zealand or the IET On-Site Guide in the UK) and the type of building. Common Maximum Demand Tables (AS/NZS 3000) max demand table

The Max Demand Table is used to determine:

: Used for Non-Domestic Installations (commercial and industrial sites). Setting the maximum demand based strictly on the

Manual spreadsheets are common, but professional tools include:

6.2 - Maximum demand and diversity - TLC Electrical Supplies It demonstrates that proper use of this table

The Maximum Demand Table is an essential document in electrical power system design, installation, and management. It serves to calculate the expected peak load (in kVA or kW) that an electrical installation will draw from the supply network. This paper explores the purpose, methodology, calculation standards (based on IEC, BS 7671, and AS/NZS 3000), and practical application of the Max Demand Table. It demonstrates that proper use of this table prevents overloading, ensures voltage stability, reduces capital expenditure on oversized equipment, and ensures compliance with regulatory safety standards.
