How many distribution-board circuit labels are needed?

Multiply the planned circuit count by the number of labels required per circuit and add any separate directory or spare labels.

Can circuit numbering start at a number other than 1?

Yes. Enter the starting circuit number used by the board schedule.

Can the planner generate the circuit sequence?

Yes. It displays the generated circuit-number range and a circuit schedule.

How the circuit label plan works

The planner creates a consecutive circuit sequence from the starting number. Labels required for those circuits are calculated independently from directory and spare labels.

Last circuit = start + circuit count − 1
Base circuit labels = circuit count × labels per circuit
Base total labels = circuit labels + directory labels
Planning labels = ceiling(base total × (1 + spare ÷ 100))

Worked example

Starting at circuit 1 with 24 circuits and one label per circuit gives circuit numbers 1–24. With two directory labels, the base quantity is 26. A 10% spare allowance produces 29 planning labels.

Why the sequence is shown

Label counts alone do not help much when the main risk is a numbering mistake. Showing the sequence lets the installer or project manager compare the generated numbers with the approved board schedule.

Frequently Asked Questions

Can circuit numbering start at 101?

Yes. Enter the actual starting number used by the board schedule.

Can there be more labels than circuits?

Yes. Directory and spare labels can exceed circuit labels for a particular procurement package.
