Overview
The ABB Blackburn CTP500250 is a high-conductivity copper compression C-Tap connector from the Color-Keyed E-Z-Ground product line. Engineered for grounding and bonding applications, this C-Tap accommodates 300 to 500 kcmil main conductors and 3/0 AWG stranded to 250 kcmil tap conductors. It provides a reliable, permanent connection that serves as an efficient alternative to exothermic welding in direct burial grounding systems.
Features
- High-conductivity copper construction ensures low-resistance electrical connections
- Rated for direct burial applications without additional protection
- Color-Keyed system for quick, error-free connector identification
- E-Z-Ground compression design provides a permanent, maintenance-free connection
- Efficient alternative to exothermic welding products
- Requires only 2 crimps for fast, reliable installation
- Compatible with T&B hydraulic tools (13100A, TBM14M, TBM14CR-LI, TBM15CR-LI, TBM15, TBM15I) using 15G121R die
- Also compatible with Burndy Y750/Y39 (U1011), Y45 (S1011), and Y46 (P1011) dies
- UL E3060 listed for safety and code compliance
