A browser-based collection of calculators and reference tables for power, networking, and cloud infrastructure.

Landing page captured for the 2026-11-05 issue.

For: Power, network, and cloud system designers
Worth noticing: The AWG check notes it does not apply NEC 240.4(D) overcurrent-protection limits for 14, 12, and 10 AWG copper.

Field notes

The AWG calculator accepts conductor size, steady current, one-way run length, and source voltage, with presets for solar and telecom feeders. Its notes distinguish design targets from code limits and disclose that the check does not apply NEC 240.4(D) protections for small conductors. The homepage says calculations run in the browser and inputs remain there.
