Anyone have any preventive maintenance tips for a commerical building with aluminum wiring?
thanks

Hydraulic-compressed pin adapters like Burndy AYPO-series are nice. T&B and Penn-Union have similar versions. http://12.30.8.43/fci/datasheet.asp?PN=AYPO250&FAM=250

Note differences in long-term “building wire” aluminum-cable performance of "EC-1350" versus "AA-8000" alloys.
