Demand factor worksheet calculator

Use this calculator when demand factors have already been selected from a source record and need to be applied to connected load groups. The page keeps the factor and source note beside each row so the adjusted demand value can be reviewed later.

Field Use Cases

This page is not a factor lookup table. It assumes the reviewer already has a basis for each factor.

Data checklist

The source note does not need to be long. It just needs to point the reviewer back to the record that justified the factor.

Review Workflow

The effective factor is only a summary of the entered rows. It does not become a new rule for other projects.

Worked factor record

A worksheet includes 30 A of lighting at 90%, 80 A of socket outlets at 60%, and 45 A of mechanical load at 75%. The connected total is 155 A.

Adjusted demand is 27 A for lighting, 48 A for socket outlets and 33.75 A for mechanical load. The adjusted total is 108.75 A. The effective demand factor for the entered rows is 70.16%, and the largest adjusted row is socket outlets.

The result is useful because the row values remain visible. A later reviewer can see which group drove the adjusted demand and which factor source needs checking.

Method boundary

This narrow method keeps the page useful without pretending to own the whole demand calculation.

Stop points

• A connected load group has no clear basis.
• A demand factor has no source note.
• A factor above 100% is not intentional.
• The adjusted total is being treated as a complete maximum-demand assessment.
• The result is being used for switchboard capacity before the board capacity source is checked.

When a stop point appears, keep the export as a source question and resolve the factor record before carrying the value downstream.
