Blackburn 4N – Frequently Asked Questions
1) What wire sizes does the Blackburn 4N service entrance connector take?
The Blackburn 4N is built for copper conductors from 6 AWG solid down to 4 AWG stranded, which is the wire range stated in the product description (6SLD-4STRN CU). It's a two-conductor mechanical connector, so it takes one run wire and one tap in copper only. Do not use it on aluminum conductors.
2) Does the Blackburn 4N connector come insulated, or do I have to tape or boot it myself?
It ships bare, with no insulation and no enclosure or cover. On any live splice you'll need to insulate the finished connection yourself with tape, a heat shrink kit, or an insulating cover sized to the connector.
3) Is the 4N a Type N split bolt connector, and does it need a crimp tool?
It's a mechanical connector, not a compression fitting, so no crimp tool or die set is needed. You tighten it with a wrench. The 4N is the Type N pattern called out in the part description, and it's sold individually.
4) What voltage can I use this copper splice connector on?
The 4N carries a 35 kV rating, so it covers standard 600 V service entrance and tap work as well as medium-voltage applications up to 35 kV when insulated appropriately for the system voltage.
5) How much room does the 4N need inside a meter socket or junction box?
The body measures 5/16 in outside diameter, so it's a compact splice that fits tight gutter and meter can work. Remember to allow extra clearance for the tape or insulating boot you add over the bare connector.
6) Will the 4N corrode if I splice copper service entrance conductors with it?
The connector body is copper alloy, so it's a like-metal joint with copper conductors and avoids the dissimilar-metal issue you get pairing copper with a plain aluminum-bodied connector. Copper only, though; it isn't a dual-rated AL/CU device.
7) Can I order the Blackburn 4N one at a time or is it bulk packed only?
It's sold each under manufacturer part number 4N, so you can buy a single unit for one repair or order by the count you need for a panel change-out.
8) Is the Blackburn 4N made in the USA for jobs with domestic sourcing requirements?
Country of origin is the United States, which covers Buy American style documentation requests on government, school, and institutional electrical work.
