Blackburn NB 500 – Frequently Asked Questions
1) What die does the Blackburn NB 500 H-type compression connector require?
The NB 500 is crimped with die index N, called out in the product name as DIE-N. You need a hydraulic or battery compression tool that accepts that die index. The connector is a compression tap, not a mechanical bolted tap, so there is no torque value to set and no re-torque later.
2) Can I use the Blackburn NB 500 on aluminum conductors, or copper only?
It is an aluminum-bodied H-tap. Aluminum-body compression taps of this type are commonly used on aluminum runs and aluminum-to-copper taps in utility and service work, and the body is bare, so the crimped joint should be filled or coated per the practice you follow for aluminum terminations.
3) Is the Blackburn NB 500 tap connector insulated, or do I have to cover it after crimping?
It ships bare with no insulation, so the installer covers it. Plan on a cold shrink tube, heat shrink, or tape build-up sized to the finished crimp if the tap lands anywhere it needs to be insulated.
4) What is an H-tap connector used for versus a split bolt?
An H-tap like the NB 500 takes a tap conductor off a continuous run without cutting the run: the main lays in one side of the H, the tap in the other, and one compression crimp locks both. A split bolt does the same job mechanically with a nut and needs re-torque and taping. The compression tap gives a permanent crimped joint and a lower profile, which matters in a crowded pull box or on a pole. The trade-off is you need the tool and the correct die.
5) How long is the Blackburn NB 500 connector body?
The catalog spec lists a 3 inch length; the part description calls it a 3-3/4 inch connector. Use the longer figure when checking whether the finished crimp and its insulating cover will clear inside a box, gutter, or enclosure, and allow extra for the tool jaw to seat squarely on the body.
6) Is the Blackburn NB 500 sold individually or in a bag?
It sells each, one connector per unit, so order the exact count of taps you need for the job rather than a carton quantity. The manufacturer part number is NB 500 and it is made in Mexico.
