Blackburn WRS719 – Frequently Asked Questions
1) What conductor sizes does the Blackburn WRS719 compression stirrup connector take?
The WRS719 is built for main conductor runs of 397 kcmil (18/1) down to 266 kcmil CSR in ACSR, and A400 to 250 kcmil stranded on the aluminum/copper side. The stirrup bail itself is sized for 2/0 tap connections. If your main run is smaller than 250 kcmil stranded, this is the wrong body size and you want a smaller stirrup connector.
2) Can I use an aluminum connector like this on copper conductors?
The body is aluminum with tin plated copper bails, so it is a dual-rated style connector body that accepts aluminum or copper main conductors. The tin plating on the bails is what keeps the stirrup contact from galvanic trouble when a copper tap is clamped on. Use the compound supplied with aluminum work and wire-brush the conductor before crimping.
3) Is the WRS719 a bolted or a crimped connector?
It is a compression fitting, not a bolted mechanical lug. You install it with a hydraulic compression tool and the correct die for the conductor size, so plan on having the press and die set on the truck before the crew goes up. Once crimped it is permanent, unlike a bolted connector you can back off and reuse.
4) Why would I use a stirrup connector instead of tapping directly onto the main line?
A stirrup gives you a fixed bail to clamp hot-line clamps or grounding clamps onto, so utility and line crews can make and break taps repeatedly without ever cutting into or abrading the main conductor. On a service run you want reworked over its life, the stirrup takes the wear instead of the main. If the tap is made once and never touched again, a plain compression tap saves the extra hardware.
5) Does the WRS719 come insulated, or do I need to cover it after installation?
No insulation on this connector. Insulation material is listed as none, so it goes on bare and any covering, boot, or tape jacket the installation calls for is a separate item you add.
6) How big is the WRS719 body? I need to know if it clears in a tight enclosure.
Stated size is 12-1/4 x 3-3/16 inches. That is a substantial piece of hardware, so on cramped gear or a crowded pole-top you need to check clearance to adjacent phases and to the enclosure wall before you commit to it.
7) Is the Blackburn WRS719 sold individually or in a box?
Sold each, so the quantity you enter is the number of connectors you get. For a three-phase tap you are ordering three.
8) What is the manufacturer part number and country of origin for this Blackburn stirrup connector?
Blackburn part number WRS719, manufactured in Mexico. Distributors quoting against a spec should reference WRS719 directly, since the bail size (2/0) and conductor range are tied to that number.
