Voltage Drop. vs Interval

Voltage Drop is a practical electrical calculation toolkit for electrical engineers, technicians, electricians, and students. Three tools in one: • VOLTAGE DROP CALCULATOR — Computes voltage drop for single/three-phase and copper/aluminum, and checks the result against your chosen 1.5%, 3% or 5% limit. It recommends the minimum cross-section that satisfies BOTH the voltage-drop limit and the current-carrying capacity. • CABLE SIZING — Finds the smallest cable cross-section required for your load and line, and lists the cable types available in that size. • CABLE CATALOG — Provides the technical features of common low-voltage cables (NYA, NYAF, NYM, H05VV-F, NYY, NAYY, NHXMH, N2XH, N2XH FE180), including current-carrying capacity tables per cross-section (in air / in conduit / in ground), right inside the app. FEATURES • Single-phase and three-phase systems • Copper and aluminum conductor support • 1.5% / 3% / 5% voltage-drop limit check with cross-section recommendation • "Suitable cables" suggestion after each calculation, with one-tap access to cable details • Cable technical-feature tables (including halogen-free cables) • Calculation history: save, reopen, delete • Works fully offline, ad-free • 9 language support PRIVACY The app does not collect any personal data. No account is required, and the values you enter never leave your device.

Plan evenly spaced pickets, balusters, hooks, brackets, slats, shelves, lights, and frames with a simple one-line layout tool. Enter the measured span, object width, and object count. Interval calculates the gap and gives you every mark position from the same starting reference. Compare Equal ends with Flush ends, then use centerlines or left edges to mark the layout. A scaled diagram makes the arrangement easy to check before you mark. Choose imperial or metric units; inch results use tape-friendly fractions and show calculated decimals when needed. If the pieces cannot fit in the span, Interval tells you why.
