Blackburn L70P – Frequently Asked Questions
1) What wire range does the Blackburn L70P mechanical lug accept?
The L70P is a single-conductor copper lug sized for 14 through 4 AWG, which is what the 14-4 in the part designation means. One conductor per lug, so for a multi-wire termination you need one lug per wire.
2) Can I use the Blackburn L70P on aluminum conductors, or is it copper only?
Copper only. The L70P is a copper-bodied, tin-plated mechanical connector catalogued as a copper connector, so run it on copper conductors. For aluminum or AL9CU dual-rated terminations you need a lug marked for aluminum use.
3) Is the Blackburn L70P a one-hole or two-hole lug?
One hole. The L70P mounts with a single bolt through one mounting hole, so it lands on a single-hole pad on a ground bar, bus, or enclosure. If your drawing calls for a two-hole NEMA pad to keep the conductor from rotating under torque, this lug will not satisfy it.
4) Is the Blackburn L70P a compression lug or a set-screw type?
Mechanical, not compression. The L70P is a mechanical connector, so the conductor is secured with a set screw and torqued down rather than crimped with a die tool. That makes it the right pick when you do not have a crimper on site or need a termination you can back out and re-land.
5) Why is the L70P lug tin-plated instead of bare copper?
The tin plating on the L70P slows oxidation on the copper body and gives a cleaner interface where the lug pad bolts to a bus bar, ground bar, or enclosure landing pad. It also makes the lug suitable for contact with plated hardware without the galvanic issue a bare copper surface can create.
6) Does the L70P come in a bag or multi-pack, or do I buy one at a time?
Sold individually. The selling unit on the L70P is each, so if you are landing six grounding conductors in a panel you order six pieces.
7) Where do I find the manufacturer part number and country of origin for the Blackburn L70P?
The Blackburn part number is L70P, and it is manufactured in Mexico. Those are the two identifiers distributors and government or institutional buyers typically need for a purchase order or a domestic-preference review.
