Shopping for 200' of 480V 400amp used busway.
Do you guys know of any good used surplus companies? We prefer Copper but noticing aluminum is more readily available. Any issues with Aluminum?

Old used aluminum bus way is risky to install, back in the day it was all aluminum. ...Modern aluminum bus way is plated and alloyed with other metals to make it more resistant to corrosion and galvanic reactions. If you choose AL, make sure its plated and alloyed.
