Why the numbers landed here

Rankability answers "can a new site rank?" Business answers "is there money if it does?" Each bar is tied to a fact from this SERP โ€” not a vibe.

  • Demand

What to build if you still go

Positioning

The go-to field voltage-drop tool for US electricians โ€” NEC edition stamped, aluminum and copper, one-way and three-phase, works in a basement with no signal.

Audiences

Journeymen sizing feeders

Manufacturer calculators are desktop-era and online-only. Wrong metal or wrong formula gets a failed inspection.

๐Ÿ“ r/electricians, supply-house WhatsApp threads, Mike Holt

Solar / EV charger installers

Long DC and AC runs. Generic calculators skip temperature and conduit fill derate.

๐Ÿ“ r/solar, Tesla Motors Club, trade Facebook groups

Content / product gaps

Offline + NEC edition

DR 14 and DR 18 tool sites rank with 1999-looking forms. None advertise offline.

โ†’ PWA, last-used jobs saved on device

Worked examples next to the math

YouTube ranks #7. People want to see a panel example, not just inputs.

โ†’ Inline example: 240V, 180ft, #2 AL, 80A continuous

Monetization

Free calc, $39/yr job vault + NEC pack

Inspectors and contractors will pay to save jobs and lock an edition.

Medium
Wire affiliate after the result

Once they have a size, they need cable. Southwire already ranks #1 โ€” you can still attach the buy step.

Low

14-day plan

Days 1โ€“4
  • Ship the calc with copper/AL, 1ฯ†/3ฯ†, 60/75/90ยฐC.
  • Put the worked example above the fold โ€” copy the YouTube job, in text.
Days 5โ€“10
  • Target this keyword and 'voltage drop calculator 3 phase'.
  • One short: screen recording of a 180ft feeder. No intro.
Days 11โ€“14
  • Add conduit-fill as a second tab (internal link to the sister seed).
  • Soft paywall: save more than three jobs.

Risks

โš ๏ธ Southwire brand trust

Do not fight the manufacturer on authority. Beat them on mobile UX and offline.

โš ๏ธ Wrong formula = angry trades

Show the formula, cite NEC table, stamp the edition.
