Blackburn PTC 500 R 350 – Frequently Asked Questions
1) What conductor sizes does the Blackburn PTC 500 R 350 reducer splice join?
The PTC 500 R 350 is a tapered copper compression reducer that transitions 500 kcmil conductor to 350 kcmil, one cable in each end. It joins two conductors, so it is a straight inline reducing splice rather than a tap or multi-port connector.
2) Does the Blackburn PTC 500 R 350 come insulated, or do I have to tape or shrink over it?
It ships bare. Insulation material is listed as none, so the installer supplies the covering, typically heat shrink or an insulating tape build-up, wherever the splice needs to be insulated for the application.
3) Is the PTC 500 R 350 a compression splice or a mechanical set-screw connector?
Compression. Both barrels are crimped with a hydraulic or battery compression tool and the correct die for the conductor size, so there are no set screws to torque and no re-torque on the splice later. If you need a connector that can be installed with hand tools and taken apart, a mechanical set-screw reducer is the other route.
4) Can I use this copper reducer on aluminum conductor?
No. It is a copper body, tin-plated, made for copper conductor. For an aluminum-to-copper or aluminum-to-aluminum transition you need a connector rated for that combination, such as an aluminum-bodied or dual-rated compression reducer with the correct oxide inhibitor.
5) How long is the Blackburn PTC 500 R 350 barrel? I need to know if it fits inside my pull box.
Overall length is 3.531 inches. Allow that plus bending room for both cables when you are laying it out in a box or gutter, and remember the finished splice will be larger once you insulate over it.
6) Will a tin-plated copper splice hold up in a wet or corrosive service entrance location?
The tin plating over copper is there for corrosion resistance, and this connector is classed for harsh environments. It is used in service entrance splicing work. Since it comes with no insulation, weather or wet-location protection depends on the shrink or tape system you build over it.
7) Do I get one connector or a pack when I order the Blackburn PTC 500 R 350?
Sold each, one reducer per unit. A 500 to 350 transition on a three-phase feeder with a neutral means four of them, so count your conductors before you order.
8) Is the Blackburn PTC 500 R 350 made in the USA?
Country of origin is the United States, which matters if you are procuring under a domestic-preference clause on a government, school, or transit job.
