Motor branch-circuit sizing

Use supported NEC 2026 motor table rows to size branch conductors and short-circuit / ground-fault protection, then review overload protection from motor nameplate data.

Calculation inputs

Motor and installation basis

Table full-load current sizes branch conductors and short-circuit / ground-fault protection. Nameplate current sizes overload protection.

Motor class

Rated voltage

Horsepower

Motor type / design row

Branch-circuit protective device

Installed device rating (optional)

Terminal temperature rating

Ambient temperature (°F)

Overload nameplate details

Nameplate current

Service factor

Temperature rise (°C)

These fields must match the motor nameplate. Leave one blank to keep overload protection unavailable until that information is known.
