Pump Cable Calculator vs Cable Guide

Calculates the proper wire size or install length needed for various installation methods of pump cable, per NEC® recommendations.

Cable Guide is the field reference for anyone who terminates, repairs, or buys cables for a living — or just wants to do it right at home. It covers 65 cable types across 10 categories: Ethernet, telephone, coaxial, fiber optic, USB, display, audio, serial / industrial, power, and structured cabling. For each cable you get: • Step-by-step how-to instructions — strip, prep, terminate, test • Pinouts with TRUE colors — T568A, T568B, crossover, rollover, RJ11, XLR, DB9, OBD-II, DMX-512, and more • SwiftUI diagrams of plug bodies, fiber jackets, and coax cross-sections in real-world colors • A list of every tool needed, with what it actually does • Specifications — bandwidth, max length, connector type, impedance, polarity • "Watch out for" warnings drawn from real-world mistakes (mixed 50/75 Ω BNCs, APC ↔ UPC fiber damage, 13 mm untwist rule, etc.) • "Where to buy" — vendor search shortcuts to Amazon, Monoprice, Home Depot, Newegg, Markertek, B&H Photo, Sweetwater, Digi-Key, Mouser, FS.com, ShowMeCables, trueCABLE, and Ubiquiti Store, so you can compare prices in three taps • "Photos" — opens a Google Images search for the exact productWhat's covered Networking: Cat5e, Cat6, Cat6a, Cat7, Cat8, crossover, Cisco rollover, console / DB9, keystone jacks, 110-block, 66-block, patch panels, DAC, AOC, USB-C ↔ Ethernet adapters.
