Wire Guide Watch

Estimate copper circuit voltage drop and save reusable circuit configurations for quick field reference.

Estimate copper conductor voltage drop without reaching for your phone. Set wire size, voltage, current, and one-way length with the Digital Crown.

Save common circuit configurations, give each record a useful name, reload values, update records, and permanently delete old jobs.

• Common AWG sizes
• Voltage and percentage drop
• Fast Crown-based input
• Persistent circuit library
• Fully offline

Reference estimate only. Follow applicable electrical codes and qualified professional guidance.
