The I-Line Advantage
Square D's I-Line busway system is everywhere — factories, warehouses, data centers, and big-box retail. That enormous installed base means constant demand for used I-Line bus plugs in every amperage from 30A to 800A, fusible and breaker types alike.
Reading the Catalog Number
Value keys on the catalog number and amperage stamped on the nameplate. PQ and PS series plugs, and the breakers inside them — QO, FA, KA, LA, MA frames — each have their own market. One clear nameplate photo answers everything, which is why we never need testing to make an offer.
Condition and Completeness
Plugs with covers, handles, and hardware intact bring the strongest money. Shelf-worn is fine; missing guts are not. If the breaker is still inside, leave it — the plug and breaker together price higher than either alone.
From Shelf to Sold
Line the plugs up, photograph the nameplates, and text the batch to us. We price the lot the same business day, pay upfront, and send freight — whether it is five plugs or five hundred.
