Blackburn IKL56 – Frequently Asked Questions
1) What wire sizes does the Blackburn IKL56 service entrance splice connect?
The IKL56 is a two-conductor compression splice sized for a 4/0 run on the A side and 1/0 on the B side, so it joins a 4/0 aluminum service conductor to a 1/0. Because the two barrels are different sizes, orientation matters on install: the larger conductor goes into the A end. It is not a same-size splice, so if both of your conductors are 4/0 you need a different sleeve.
2) Can I use an aluminum splice like the Blackburn IKL56 on copper conductors?
The IKL56 body is aluminum, and it is built as an aluminum service entrance splice. For a copper-to-copper or a copper-to-aluminum transition on a service run, use a connector rated for those conductor materials rather than this one. Match the connector to the conductor metal on both ends before you crimp.
3) Does the Blackburn IKL56 splice meet ANSI C119.4 for underground and service connectors?
Yes. The IKL56 passes the requirements of ANSI C119.4 and is RUS Listed, which is the pair of credentials a utility or co-op inspector normally looks for on a service entrance splice. If your spec sheet calls out RUS acceptance for the connector, this one satisfies it.
4) How long is the Blackburn IKL56 splice sleeve, and will it fit inside my enclosure?
The sleeve measures 5-1/2 inches with a 4 inch splice length, so you need roughly six inches of straight, clear run plus room to swing a crimp head. In a tight meter socket or a shallow pedestal, lay it out before you strip: a compression sleeve this length will not tolerate being bent into position after crimping.
5) Is the Blackburn IKL56 a compression splice or a set screw connector?
Compression. The IKL56 is crimped with a die tool, not tightened with a set screw or bolt, so you need the matching compression tool and die on site to install it. A set screw or mechanical connector is the choice when you want a field-serviceable connection you can back off later; a compression splice is a permanent joint and is what most utility service entrance specs require.
6) Does the Blackburn IKL56 splice come insulated?
The IKL56 is supplied insulated, so you are not building up tape or a heat shrink sleeve over a bare barrel after the crimp. Confirm the insulation is undamaged after crimping, since the die pressure is what most often splits a jacket on a service size splice.
7) How many Blackburn IKL56 splices come in a box?
The IKL56 is packaged 100 to a box, so it is bought as a stocking quantity for a crew or a service truck rather than as a single piece. For a one-off repair that is a lot of connector to carry; for a co-op or a contractor running repeated 4/0 to 1/0 service transitions, one box covers a season.
8) Is the Blackburn IKL56 splice made in the USA for Buy American jobs?
Country of origin on the IKL56 is the United States. On federal, municipal, and utility work carrying domestic sourcing language, that is the line a procurement officer needs in the submittal.
9) What is the manufacturer part number for the Blackburn 4/0 to 1/0 aluminum service entrance splice?
Blackburn IKL56 is the part number for the aluminum service entrance compression splice taking 4/0 on the A side and 1/0 on the B side. Order by IKL56; the number carries the conductor combination, and adjacent numbers in the family cover different size pairings.
