USER GUIDE

Start with clarity. Work with confidence.

Enter the right inputs, understand the results and keep a record for your project.

One circuit, four steps

Each tool works independently. For a complete workflow, use the transfer buttons in the results to carry relevant inputs to the next step.

Enter equipment input power, quantity and demand factors.

Transfer load current; choose conductor, installation and actual route length.

Check segment voltage drop against your budget; account for upstream drop separately.

Screen CB ratings. Supply verified fault-current and breaking-capacity data when available.

Use electrical input power, not shaft power or cooling capacity. Check W/kW and phase/line voltage.

Temperature, grouped circuits and power factor affect the result. Open Additional settings and the ? buttons for help.

Results update automatically with valid inputs. While errors remain, previous results cannot be saved or transferred.

Review the method, comparison tables and warnings. Preliminary results do not establish full compliance or approve an installed product.

Sign in and open Organisations & Projects to create or select a workspace.
Optionally name the calculation, complete it and choose Save to project.
Open Saved history to review earlier revisions. Recalculating and saving creates a new revision.
Open Project report / PDF, then choose Print / Save PDF in your browser.

Do I need an account to calculate?

No. Calculations are available without an account; an account is needed to save results and manage projects.

Does a draft replace saving?

No. Drafts are kept in the browser tab and may be lost when it closes. Save results to a project for a lasting record.

Where can I enable dark mode?

Use the moon/sun button in the top bar. Your browser remembers your choice.
