A production line that trips "randomly" is rarely random. Before replacing breakers or upsizing anything, split the problem into 3 layers — most warehouse tripping issues in Southern California fall into one of them:
Layer 1 — Power supply. Is the incoming power clean and adequate? Utility voltage sags, an undersized service, or a loose service connection can drop voltage under load, making motors draw excess current and trip. Check here first — it's the cheapest to rule out.
Layer 2 — The load itself. Motors with failing bearings, jammed conveyors, or dust-choked equipment draw more current than their nameplate. If the trip follows a specific machine or shift, the load is talking to you.
Layer 3 — Protection settings. Breakers and VFDs with wrong trip curves, setpoints, or parameters will nuisance-trip on a healthy system. This is the most overlooked layer — and often the cheapest fix.
Work the layers in order: supply → load → settings. Jumping straight to bigger breakers without diagnosing just moves the failure point somewhere more expensive.
