How teams use this section
Use these workflows to choose the right calculator path before moving into deeper analysis or formal design checks.
Feeder voltage drop and conductor sizing
Translate length, current, and material into realistic drop estimates, then compare against common practice targets for the installation type.
Three-phase power and current sanity checks
Relate voltage, current, power factor, and real/reactive power so downstream breaker and cable assumptions stay aligned.
Conductor resistance and loss awareness
Connect resistance temperature behavior to I²R losses when efficiency or thermal rise is part of the decision.
Battery runtime and DC plant checks
Bridge load profiles, efficiency assumptions, and capacity derates for quick DC energy budgeting.
Guides for this section
Published guides help explain assumptions, formulas, and the next step after a quick calculator result.
Use this guide for preliminary electrical checks where transparent resistance assumptions are required before detailed code-based design.
Primary tool: Voltage Drop Calculator
Use this guide when you need fast clarity on balanced three-phase power relationships and where simplified formulas are valid.
Primary tool: Three-Phase Power Calculator

Electrical & Power FAQ
Are results valid for every national electrical code?
No. Codes, derating tables, and installation rules vary by region. Use these workflows as structured math checks, then apply the governing standard and local amendments.
Why separate voltage drop from breaker sizing?
They answer different questions: drop is about steady-state performance and flicker perception, while protection is about fault coordination and device ratings. Keeping them distinct reduces dangerous mixing of criteria.
Do you store project inputs in the browser?
Fluranto is built browser-first without requiring an account wall for these workflows. Treat sensitive site data according to your own policy; do not rely on this hub as secure project storage.
