Blackburn L70SS – Frequently Asked Questions
1) What wire sizes does the Blackburn L70SS terminal lug accept?
The L70SS takes copper conductors from 14 AWG up to 4 AWG. That range covers everything from small control and branch-circuit wiring through to a 4 AWG feeder or ground conductor, so one part number handles a lot of panel and equipment terminations. It is a single conductor lug, so one wire per lug.
2) Can I land two wires in one Blackburn L70SS lug?
No. The L70SS is a single conductor lug, one wire per barrel. If you need two conductors landed at one point you need a dual or multi-conductor lug, or a second lug on the same pad where the equipment allows it. Doubling up in a single-conductor barrel is not a listed use and it will not clamp both wires reliably.
3) Is the Blackburn L70SS lug copper or aluminum, and can I use it on aluminum conductors?
It is a copper-body lug, so it is intended for copper conductors. Aluminum or copper-clad aluminum wire needs an AL9CU dual-rated connector instead. Using a copper-only lug on aluminum invites galvanic corrosion and a loose connection over time.
4) Why does the L70SS use a stainless steel screw instead of a standard one?
The setscrew on this Blackburn lug is stainless, which resists corrosion in damp, outdoor, or wash-down locations better than a plated steel screw. For electricians terminating in exterior enclosures, pump panels, or coastal installs, that is the practical reason to specify the SS version over a plain-screw lug.
5) Will the L70SS work as a ground or bonding lug on a panel?
It is a mechanical cable or wire lug for copper conductors 14 through 4 AWG, which is the usual range for equipment grounding and bonding conductors in commercial panels. Confirm your equipment's pad drilling and screw size match the lug's mounting before you commit to it for a bonding point.
6) Is the Blackburn L70SS sold individually or in a bag?
It is sold each. Order the exact quantity of terminations you need, which is useful when you are only replacing a handful of lugs on a panel rather than kitting out a full job.
7) What is the correct part number and country of origin for the Blackburn copper terminal lug with stainless screw?
The manufacturer part number is L70SS, from Blackburn, and it is made in Mexico. Distributors cross-referencing a submittal should quote L70SS specifically, since the SS suffix identifies the stainless setscrew version.
