Blackburn SWC150A1490 – Frequently Asked Questions
1) Is the SWC150A1490 braid the same on both ends, or does it have different hole patterns?
The two ends are different. One terminal pad is 4-hole and the other is 2-hole, so orientation matters when you mount it. Check that the 4-hole NEMA pattern lands on the equipment pad drilled for four holes and the 2-hole end on the two-hole connection before you torque anything down.
2) Why use a flexible braid instead of a solid copper bonding bar or a cable jumper?
A braid is the choice wherever the two connection points move: seismic joints, vibrating equipment, drawout gear, expansion sections of bus. The flat flexible construction takes repeated movement without work-hardening or loading the terminal pads the way a rigid bar would, and the flat profile packs into tight gear sections better than a round cable of equivalent copper. If both ends are fixed and rigid, a bar or a standard grounding conductor is the simpler part.
3) Is the Blackburn braid connector tinned, and does that matter for outdoor or damp locations?
The conductor is tin-plated copper. The tin plating slows oxidation at the braid surface and at the bolted pad interface, which is why tinned parts are the usual specification for exterior gear, substation yards, and damp or corrosive indoor areas. Bare copper braid is normally reserved for dry indoor use.
4) Are the mounting bolts and washers included with this Blackburn braid jumper?
No. The SWC150A1490 is supplied as the braid assembly with its drilled 4-hole and 2-hole pads only. The bolts, nuts, flat and Belleville washers for each pad are separate, and they need to match the hole size and spacing on the equipment pads you're landing on.
5) Does the SWC150A1490 come as a single piece, or do I have to buy a pack?
It's sold individually, one braid per unit, under manufacturer part number SWC150A1490. So if you're bonding four enclosures you order four.
6) Where is the Blackburn SWC150A1490 braid made? I have a domestic-content requirement on the job.
Country of origin is the United States. That's the point to cite on federally funded or Buy American flagged work, though the specifying authority normally wants the manufacturer's own certification letter on file as well.
