- Circuit breaker example for continuous-load sizing and standard OCPD selection.
Raceway and box examples
- Conduit fill examples for raceway sizing and mixed conductor sets.
- Box fill examples for device yokes, grounds, and clamp counts.
- Conduit fill field guide and box fill field guide for the quick-reference version.
Motor and fault examples

- Short-circuit examples for point-to-point estimates and AIC screening.
How to use this index by skill level
Apprentices should start with the long-form guide pages, then move into the calculators. Journeymen usually want the worked example only when the job falls outside the normal pattern. Foremen and estimators often use the examples as a quick sanity check before they pass the work to the field.
Frequently Asked Questions
What kinds of examples are included here?
This page organizes SparkShift's existing examples and support pages into practical buckets so you can jump to residential, commercial, motor, raceway, and exam-style workflows faster.
Is this only for apprentices?
No. Apprentices use it for practice, but experienced electricians can also use it as a fast index into the right calculator guide or field reference when a job sends them outside the routine.
Should I start with the worked example or the live calculator?
If the workflow feels unfamiliar, start with the worked example. If you already know the path and just need the answer faster, go straight to the live calculator.
Does this replace exam prep?
No. It complements broader exam prep by making the example-heavy calculator content easier to find and revisit.
