Quote 400 Amp Units
Send photos of the nameplates and receive a firm number, usually the same day. No obligation.
Funds change hands before a single section leaves your property. There is no consignment and no waiting on a downstream resale.
Our own crew takes the run down. You are not sourcing riggers, renting lifts or chasing a carrier who has never handled busway before.
You are never asked to test, megger or certify anything. We grade from physical condition and the nameplate. That is the entire process.
Fusible plugs, breaker units, bus duct, tap boxes, panelboards and starters all on one job is the normal case rather than the exception.
400 Amp equipment we buy
Individually valuable enough that a single unit is worth a phone call, particularly breaker units where the breaker inside carries its own market.
At this size the breaker or switch inside often drives the number more than the housing does, so a nameplate photo matters.

400 Amp bus plug questions
Straight answers
What is a used 400 Amp bus plug worth?
It depends on the busway line, the manufacturer and the physical condition far more than on the amp rating alone. Two 400 Amp units can be worth very different numbers if one fits a discontinued line with a large installed base and the other fits a line still in production. Send the nameplate and we will price yours specifically.
Do you buy single 400 Amp units or only full pallets?
Individually valuable enough that a single unit is worth a phone call, particularly breaker units where the breaker inside carries its own market.
How does 400 Amp equipment usually come to us?
Palletised individually, moved with a forklift. We buy all of those.
Does the 400 Amp unit have to be copper bus?
No. We buy both copper and aluminum bus at this rating. Aluminum bus was standard on a great many installations and has its own active resale market.
