What this worksheet captures
This worksheet is built to capture the field details that usually decide whether molded case breaker verification can move into a quote, replacement, or engineering review.
It is meant to keep the intake practical, consistent, and easier to hand off between maintenance, engineering, and purchasing.
- current rating
- trip setting or frame
- system voltage
- protection job
- mounting and accessory details
When to use it
Use it when the field information is incomplete, when multiple people are touching the job, or when the replacement path depends on details that are easy to miss over email or phone.
Checklist
Fill this in on-screen or print the page and carry it into the field so the same core details make it back to engineering, sourcing, or quote review.
| Check item | Status | Notes |
|---|---|---|
Current rating Inspect the installed equipment directly and note whether this checkpoint is verified, questionable, or not applicable. |
||
Trip setting or frame Capture the current dial position, trip class, or frame detail exactly as installed before changing anything. |
||
System voltage Inspect the installed equipment directly and note whether this checkpoint is verified, questionable, or not applicable. |
||
Protection job Describe whether the device is being used for branch protection, motor protection, control-circuit protection, or another specific role. |
||
Mounting and accessory details Capture the exact family, ratings, fit details, and accessories that the next part still has to match. |
How to use it on site
Work from the installed equipment first, then collect the ratings, environment, fit notes, and related components that change the actual buying decision.
| Item | What it means in practice | Why buyers care |
|---|---|---|
| Core role | Resettable overcurrent protection matched to a specific protection classification | This is why breaker family matters so much. |
| What engineers compare first | listing, voltage, amp range, interrupting rating, and trip behavior | Those checks decide whether the breaker belongs in the circuit. |
| Typical supporting parts | aux contacts, shunt trips, handles, and coordination with fuses or starters | Breaker decisions affect the rest of the assembly. |
| Common confusion | Using a supplementary protector where branch protection is required | That mistake creates both performance and compliance problems. |
What to verify before sending it on
A worksheet is most useful when the captured values are checked for completeness before they move into sourcing or quote prep.
Important verification notes
Use the worksheet to structure the job, then confirm the final release path against the exact product-family data and installed conditions.
