Blackburn E-APS41-25 – Frequently Asked Questions
1) What wire sizes does the Blackburn E-APS41-25 split-bolt connector take?
The E-APS41 dual-rated split bolt covers a 4/0 through 2 AWG range, so it handles the main and tap conductors typical of service and feeder splices in that band. The body is aluminum with a tin plating.
2) Can I use this aluminum split bolt on copper conductors, or copper to aluminum?
It is a dual rated (AL/CU) connector, so it is suitable for aluminum to aluminum, copper to copper, and aluminum to copper splices. The tin plating over the aluminum body is what makes the copper contact acceptable and limits galvanic corrosion at the joint. Use the appropriate oxide inhibitor and torque practice for aluminum work.
3) Is the Blackburn E-APS41-25 sold as a single connector or a box of 25?
The E-APS41-25 is the 25 pack of the E-APS41 split bolt. The catalog sells it by the each, so one unit ordered is one 25 piece pack, not one connector. Order accordingly if you only need a handful for a panel change.
4) Do I still need to tape or insulate a split bolt splice like this?
Yes. A split bolt is a bare mechanical connector, not an insulated device. After torquing the splice you need to build the insulation back up with rubber splicing tape and a vinyl jacket, or fit an insulating cover, before the conductors go back in the raceway or enclosure.
5) Is a split bolt or a compression connector the right choice for a 4/0 tap?
A split bolt like the E-APS41 is mechanical, so it installs with a wrench only and can be taken apart later, which suits maintenance splices, taps in pull boxes, and grounding work where no crimp tool is on the truck. A compression lug or H tap needs a hydraulic crimper and dies but gives a permanent, lower profile joint that is easier to insulate in tight gutters. If the splice has to fit inside a crowded box, measure your space first, since split bolts with tape buildup take more room.
6) Where is the Blackburn E-APS41 split bolt made?
Country of origin on the E-APS41 is Mexico, which is the detail government and institutional buyers with domestic sourcing rules usually need on the submittal.
