Blackburn PTC 2500 R 1750 – Frequently Asked Questions
1) What cable sizes does the Blackburn PTC 2500 R 1750 reducer splice together?
It's a tapered reducing splice that joins a 2500 kcmil conductor to a 1750 kcmil conductor, which is what the 2500-1750 in the designation means. One barrel per end, two conductors total, so it's a straight inline transition rather than a tap or a multi-tap block.
2) Is the PTC 2500 R 1750 a compression fitting or does it use setscrews?
Compression only. Both barrels are crimped with a hydraulic compression tool and the correct die set for the barrel size, so there are no setscrews or bolts involved. Once crimped it's a permanent connection, not something you can back off and reuse.
3) Does this Blackburn reducer come insulated, or do I have to cover it myself?
It ships bare, with no insulation on the body. Plan on your own cover after crimping: heat shrink, cold shrink, or tape build-up to match the cable insulation level. At 8.25 inches long, size the shrink sleeve to cover the full barrel plus overlap onto both conductors.
4) Is the PTC 2500 R 1750 copper or aluminum, and can I use it on aluminum cable?
The barrel is copper with tin plating, so it's intended for copper conductors. For an aluminum-to-copper or aluminum-to-aluminum transition at these sizes you want a bimetallic or AL9CU-rated reducer instead, not this one.
5) Will an 8-1/4 inch splice fit inside my pullbox or manhole?
The body measures 8.25 inches in length, and that's before you add heat shrink overlap and the bending radius needed on 2500 and 1750 kcmil cable. In tight pullboxes and handholes that's the dimension that decides it, so check your clear working space end to end before committing to a compression reducer of this size.
6) Can this copper compression reducer be used in a wet or corrosive location?
It's rated for harsh environments, and the copper body is tin-plated, which is the plating normally specified to slow corrosion and to keep the connector from galling in damp or chemically aggressive locations. Insulate and seal the finished splice appropriately for the vault or duct it lands in.
7) Is this Blackburn connector made in the USA for a Buy American job?
Country of origin on the PTC 2500 R 1750 is the United States, which is the line item institutional and government procurement teams usually need documented on electrical connectors.
8) What part number do I give my distributor for a 2500 to 1750 kcmil copper compression reducer?
Blackburn PTC 2500 R 1750 is the manufacturer part number. Quote it exactly, since the PTC series numbering carries both barrel sizes and a single digit change puts you on a different reducer.
9) How is the Blackburn PTC 2500 R 1750 sold, individually or in a box?
Sold each. One reducer per order, so if you're splicing three phases plus a neutral, order the quantity you need per conductor run.
