Blackburn WR502 – Frequently Asked Questions
1) What wire sizes does the Blackburn WR502 H-tap connector take?
The WR502 is sized for a 4/0 to 3/0 ACSR run conductor with an 8 to 10 tap, per the Blackburn part description. It is an aluminum H-type compression tap, so it is used on aluminum and ACSR conductors, not as a mechanical set-screw connector.
2) Is the WR502 crimped or does it use set screws?
Compression only. The WR502 is installed with a hydraulic or battery crimp tool and the correct die for an H-tap of this size, then normally covered with tape or a separate insulating cover. There are no screws to torque and nothing to retighten later.
3) Does the Blackburn WR502 come insulated?
No. It ships bare aluminum with no insulation, so the splice has to be insulated in the field with tape, a shrink sleeve, or a molded H-tap cover sized for a 1-1/2 inch long body.
4) Will a WR502 H-tap meet utility and inspector spec for a service tap?
It is RUS accepted and complies with ANSI C119.4, which is the standard covering electric connectors for use between aluminum and copper conductors. That is the spec most utilities and engineers call out on a compression tap.
5) Can I use this H-tap on 90 degree C rated cable?
Yes, the WR502 is rated for conductor operating temperatures up to 90 C, so it can be used with 90 C rated aluminum and ACSR conductors without derating the connection below the cable rating.
6) How many conductors go into a WR502 H-tap?
Three. The body accepts the run conductor plus taps for a total of three conductors in the crimp, which is what separates an H-type tap from a straight two-conductor splice sleeve.
7) How much space do I need in the pedestal or handhole for this tap?
The connector body is 1-1/2 inches long, plus the stripped conductor length and whatever insulating cover you add over it. Allow for tool jaw clearance around the body too, since a hydraulic crimp head needs room to close square on the tap.
8) Is the WR502 sold in bags or individually?
Each. Blackburn WR502 H-taps are sold as single pieces, so you order the exact count for the number of taps on the job rather than a fixed carton quantity.
