Cutler-Hammer FAQs
How do I identify my breaker frame/series (FD, HFD, etc.)?
Start with the full part number and label photo. Frame/series, poles, voltage, and AIC must match. If you’re unsure, send us the nameplate and mounting/lug photos for verification.
Why do some items show Westinghouse and Cutler-Hammer together?
Legacy equipment may be branded differently depending on era. We’ll confirm compatibility by series, dimensions, mounting, and electrical specs before you purchase.
What information should I send for fast matching?
Part number, amperage, voltage, poles, trip unit (LSI/LSIG), mounting style, and photos of lugs/line-load orientation. For bus plugs: series (TAP/ITAP/ZTAP), wire/ground, and stab configuration photos.
Can you help differentiate TAP vs ITAP vs ZTAP bus plugs?
Yes—these can look similar but are not interchangeable. Send photos of stabs, neutral position, and hanger width (if applicable) and we’ll confirm the correct series.
Do you offer trip unit upgrades or ground fault options?
In many cases, yes. We can quote AC Pro / AC Pro II trip unit options for compatible breaker styles and requirements (LSI/LSIG). Contact us with breaker details to confirm fit.
