Blackburn L70 – Frequently Asked Questions

1) What wire sizes does the Blackburn L70 mechanical connector accept?
The L70 takes a single conductor from 14 AWG up to 4 AWG, so one lug covers most branch circuit and feeder grounding conductors you run into on a panel or equipment ground bar. It is a one-conductor, one-hole mount lug, so each wire needs its own connector.
2) Can I use the L70 connector on aluminum conductors?
No. The L70 is a copper-bodied connector specified for copper conductors. For aluminum or dual-rated work you need a lug marked AL9CU or similar; putting bare aluminum into a copper-only lug is a code and corrosion problem.
3) Do I need a crimp tool or die set to install the Blackburn L70?
No crimper needed. It is a mechanical set screw connector with a slotted screw, so a flat blade screwdriver torqued to the marking on the lug is all the installation takes. That also means you can back the screw out and re-terminate during service without cutting the conductor back.
4) Does the Blackburn L70 come with mounting hardware, and how is it fastened?
It ships as a one-hole mount lug with mounting hardware included. The single hole bolts it to a ground bar, enclosure pad, or panel surface; you supply the bonding screw or stud if the equipment does not already have one.
5) Is the L70 lug insulated, or do I need to cover the termination?
Bare metal, no insulation on the body. For grounding and bonding inside an enclosure that is normal, but if the conductor is a live phase in an accessible location you will need to provide your own boot or barrier to keep it out of reach.
6) How is the Blackburn L70 sold, individually or in packs?
Sold each, one connector per unit, under manufacturer part number L70. If you are landing multiple conductors on a bar, count one L70 per wire since it is a single conductor lug.
7) Will a copper mechanical connector like the L70 hold up in a damp or corrosive panel location?
The body is copper, which resists corrosion and keeps conductivity stable over time on copper-to-copper terminations. There is no plating or insulation involved, so avoid direct contact with dissimilar metals such as bare aluminum at the mounting pad to prevent galvanic corrosion.
