Frequently Asked Questions
Q: What is the difference between Bronze and Brass Vise Connectors? A: Bronze Vise Connectors typically contain Copper and Tin as primary alloying elements, providing superior corrosion resistance and mechanical strength compared to Brass connectors, which contain Copper and Zinc. Bronze connectors are preferred for underground and corrosive environments due to their enhanced resistance to dezincification and stress corrosion cracking.
Q: Can Bronze Vise Connectors be used with Aluminum conductors? A: Yes, but proper installation practices must be followed. We recommend using a conductive anti-oxidation compound at the connection point to prevent galvanic corrosion between dissimilar metals. Our BVC-1003 and BVC-2002 models are specifically designed for Copper-to-Aluminum connections.
Q: What is the recommended installation torque for Bronze Vise Connectors? A: Recommended torque values vary by model, ranging from 15 ft-lbs for smaller connectors to 40 ft-lbs for larger models. Always refer to the product-specific installation guide for precise torque specifications. Over-torquing can damage the connector or conductor, while under-torquing may result in poor electrical connection.
Q: How do I select the right Bronze Vise Connector for my application? A: Selection depends on several factors including conductor size, installation environment, current requirements, and mechanical load. Our technical team can assist in selecting the appropriate connector based on your specific parameters.
Q: What is the expected service life of your Bronze Vise Connectors? A: When properly installed, our Bronze Vise Connectors are designed for a service life of 30+ years in normal environments and 20+ years in harsh environments such as coastal or industrial areas. Regular inspection and maintenance can further extend service life.
Q: Do your Bronze Vise Connectors comply with UL 467 requirements? A: Yes, our Bronze Vise Connectors are designed and tested to meet or exceed UL 467 standards for grounding and bonding equipment. Certification documentation is available upon request.
Q: How do Bronze Vise Connectors perform in high-fault current situations? A: Our connectors are engineered to withstand high fault currents without damage. Standard models can handle 10kA for 3 seconds, while heavy-duty models can withstand up to 25kA. Actual performance depends on installation quality and system parameters.
Q: Can custom Bronze Vise Connectors be manufactured for specific applications? A: Yes, we offer custom design and manufacturing services for specialized applications. Minimum order quantities apply, and development lead times typically range from 4-8 weeks depending on complexity.
Q: What maintenance is required for Bronze Vise Connectors? A: Bronze Vise Connectors require minimal maintenance. We recommend periodic visual inspection for signs of corrosion or loosening, and torque verification during scheduled maintenance. In highly corrosive environments, applying protective coating during installation can further extend service life.
Q: Are your Bronze Vise Connectors suitable for direct burial applications? A: Yes, our Bronze Vise Connectors are suitable for direct burial applications due to their excellent corrosion resistance. For enhanced protection in highly corrosive soils, we recommend models with additional protective finishes or encapsulation.
