Blackburn WRS352 – Frequently Asked Questions
1) What conductor sizes does the Blackburn WRS352 compression stirrup connector take?
The WRS352 is sized for 4/0 to 3/0 conductors, listed as 4/0 to 3/0 CSR and 4/0 to 3/0 stranded AWG. It's a two-sided connector, so both conductor ports fall in that same range. If your run is smaller than 3/0 or larger than 4/0, this is the wrong body size and you need a different catalog number in the WR series.
2) Is the Blackburn WRS352 a bolted connector or does it need a crimp tool?
Compression only. The WRS352 is a compression connector, so it gets installed with a hydraulic or battery crimp tool and the correct die for the barrel, not tightened down with set screws. Plan the tool and die into the job before you pull the connector out of the box.
3) Can I use the Blackburn WRS352 on aluminum conductors, or copper only?
The body is aluminum, and the wire range covers ACSR/stranded conductors in 4/0 to 3/0, so it's built for aluminum overhead work. The tin plated copper bails handle the clamp side. Tin plating on the copper is what keeps the dissimilar-metal joint from galvanic trouble.
4) What is the stirrup on the WRS352 for?
The stirrup (bail) gives you a hot-line clamp attachment point on a tap or service connection, so a lineman can land a clamp without working directly on the main conductor. On the WRS352 the bails are tin plated copper while the connector body is aluminum, which is what lets a copper hot-line clamp mate to an aluminum run.
5) Does the WRS352 come insulated or do I need to cover it?
No insulation on it. The WRS352 is a bare connector, so any covering, tape, or insulating boot the installation calls for has to be specified separately.
6) How big is the Blackburn WRS352 stirrup connector, and will it clear in a tight crossarm space?
Overall size is listed at 10 x 2-15/16 inches. That's a long body for a 4/0 connector, so check your clearance between the conductor and any adjacent hardware or phase spacing before you commit to it on a crowded crossarm or in a pedestal.
7) Is the Blackburn WRS352 sold individually or in a box quantity?
Each. The WRS352 is sold as a single connector, so the quantity you order is the number of connectors you get.
8) What is the manufacturer part number for this Blackburn compression stirrup, and where is it made?
Blackburn part number WRS352, manufactured in Mexico. That's the number to quote for a match on a utility material spec or a re-order.
