Practical Calculators for Motorsport Systems & Harness Engineers

Working with a bunch of tools? We can't help you with that, but we can provide a set of free browser-based calculators for E/E and harness design. No installs - each one runs straight from your browser, on the bench, at your desk or on your phone.

Built to help us design faster and with more confidence, drawing on years of F1 and FE harness design work. Shared here in case they save you some time too.

• Wire Sizer: Wire current capacity with staged derating, voltage drop over distance.

• Bundle Sizer: Pack wires into a bundle and see the overall diameter, with a clear visual and colour-coded gauge key.

• Connector Boot Sizer: Raychem and Hellermann boots sized against connector knurl and bundle diameter, with expanded and recovered visuals to help you pick the right one.

• Transition Boot Sizer: Non-lipped "A" style Raychem boots sized against your bundle groups at a transition, with expanded and recovered visuals.

Disclaimer - don't be a wounder. These free tools are for guidance only. The ultimate decision on boot, sleeving or wire size is down to you.
