Blackburn 2B500W – Frequently Asked Questions
1) What conductor size range does the Blackburn 2B500W two-bolt connector take?
The 2B500W is built for 300 through 500 kcmil conductors. It's a two-bolt mechanical connector with a spacer, so it handles that heavy range on a run or tap without needing a crimp tool.
2) Is the Blackburn 2B500W connector copper or aluminum?
Copper body. That means it is intended for copper conductors, not for aluminum or dual-rated AL/CU work. If the run on your job is aluminum, you need a dual-rated or aluminum-bodied connector instead.
3) Does the 2B500W two-bolt connector carry a UL listing?
It's covered under UL file E9809. That's the listing reference to quote when an inspector or a spec writer asks for the connector's UL documentation.
4) What does the spacer do on a two-bolt connector like the 2B500W?
The spacer sits between the two conductors in the connector body so each one seats in its own channel instead of bearing directly on the other. On a 300 to 500 kcmil splice or tap that keeps the pressure even across both conductors when you torque the two bolts down.
5) What is the manufacturer part number for this Blackburn copper two-bolt connector?
Blackburn 2B500W is the catalog number, and that's the number to put on the submittal or the purchase order. It identifies the copper two-bolt connector with spacer for 300 to 500 kcmil.
