Blackburn CF4010-1 – Frequently Asked Questions
1) What conductor sizes does the Blackburn CF4010-1 H-tap take on the main and the tap?
The CF4010-1 covers 4/0, 3/0 and 2/0 on the run, with 2 and 1 AWG on the tap. By conductor OD, the main range is .528 to .414 inch and the tap range is .292 to .373 inch. Measure the bare conductor before you crimp: anything outside those diameters won't compress properly in this barrel.
2) Is the Blackburn CF4010-1 tap connector for copper or aluminum conductors?
Copper only. The CF4010-1 is a bare copper H-type compression tap, with no insulation on the body, so it is applied to copper conductors and then taped or covered in the field.
3) Do I need a crimp tool for the CF4010-1, or can it be bolted?
It's a compression connector, not a mechanical set-screw tap, so it has to be crimped with a hydraulic or battery compression tool and the die matched to the connector. There are no bolts or screws to torque. If you want a re-openable connection you can service later, a mechanical split-bolt or set-screw tap is the better choice.
4) Can I use the CF4010-1 to tap a 1 AWG branch off a 4/0 feeder?
That's exactly the combination it's built for. The main side accepts 4/0 down to 2/0 and the tap side takes 1 or 2 AWG, so a 1 AWG branch off a 4/0 copper run is within range. Both conductors must be copper and within the stated diameters, main .528 to .414 inch and tap .292 to .373 inch.
5) How long is the Blackburn CF4010-1 barrel, and will it fit in a tight pedestal or handhole?
The connector body is 1-1/8 inch long, so it takes up very little room on the run. Plan for the crimp head and die clearance around it, plus space for insulating tape or a cover since the body ships bare.
6) Is the CF4010-1 acceptable for rural electric utility work?
Yes, the CF4010-1 is RUS Accepted, which is what utility and co-op specs typically call for on distribution and service tap connectors.
7) Does the Blackburn CF4010-1 come insulated, or do I have to cover the tap myself?
It comes bare with no insulation, so the installer insulates after crimping, normally with rubber splicing tape and a vinyl overwrap or a molded cover sized to the connector. For a tap that needs to be insulated out of the box, look for a pre-insulated compression tap instead.
8) Is the CF4010-1 sold individually or in a box?
It is sold each, so quantity ordered equals the number of connectors you get. Order one per tap point, and add spares since a compression connector is single-use once crimped.
9) What is the exact part number and where is the Blackburn CF4010-1 made?
The manufacturer part number is CF4010-1, a Blackburn copper H-type compression tap, produced in Mexico.
