How to use the Electrical Load Calculator
Prepare an early electrical-load conversation before circuit, cable, protection and supply design.
Material sizes & reference dimensions
Use these as common planning references only. Actual product sizes, structural dimensions and effective coverage can vary by manufacturer, region, design and specification.
Cost guide
Use the result as a planning input, then apply current local rates, lender terms, utility tariffs or supplier quotations as relevant. Keep taxes, fees, labour, delivery and contingency visible rather than hiding them inside one rate.
Calculated quantity × current unit rate + labour + transport + taxes + accessories + waste/contingency = preliminary project budget.
Practical accuracy tips
- List high-load appliances and future additions separately.
- A qualified electrician must design circuits, protection and earthing.
