FAQs
Q: Why should I use a Brown color-coded splice for my #2 AWG wire?
A: Color coding is an international safety standard. The Brown code specifically identifies the connector for #2 AWG conductors, ensuring that technicians use the correct Die Index 33 tool. This matching process is vital to achieving a certified, gas-tight crimp that prevents overheating.
Q: Can I use the L3-BS2 splice for both indoor and outdoor applications?
A: Yes. All XLUIG copper splices are treated with high-grade electro-tin plating. This finish provides exceptional resistance to oxidation and corrosion, making them suitable for use in telecommunications, power distribution, and industrial environments both indoors and outdoors.
Q: What is the advantage of a seamless barrel in the XLUIG L3-BS2 model?
A: A seamless barrel is forged from a single piece of T2 copper, meaning there are no weak seams that could split during hydraulic compression. This construction ensures 360-degree uniform pressure on the wire strands, providing maximum conductivity and mechanical pull-out strength.
