Circuit Breaker Cable Lug 50mm² X 8mm Stud (5)

Pack Contents

5 x narrow palm circuit breaker copper cable lugs, 50 mm², M8 stud
Price is per pack of 5

Features

Supplied in a convenient pack of 5
Narrow palm designed to fit circuit breakers, isolators and other tight terminals where a standard lug palm is too wide
Bellmouth (flared) barrel entry makes fine-stranded flexible cable easy to insert without splayed strands
Made from high-conductivity copper (99.9% IACS) with low oxygen content, so it crimps cleanly
Electro-tin plated (5-10 microns) for corrosion resistance
Inspection window to confirm the cable is fully inserted
Rated from -55°C to +155°C

Where to use it

Circuit breaker lugs terminate 50 mm² copper cable onto an M8 stud where space is tight, such as DC circuit breakers, battery isolators, switchboards and compact control panels. The narrower palm lines up neatly in close-pitched terminals and helps keep clearance between phases or to ground. Crimped correctly they give a low-resistance, high-current connection that stays tight under vibration. Ideal for 12V, 24V and 48V DC systems in 4WDs, caravans, boats and off-grid solar and battery installs. The pack of 5 is ideal for a single install or a few spares.

Cabins

Match two things: the cable size in mm² (for example 16mm² or 50mm²) and the stud or bolt size it fits over (for example M8). The cable size must match the lug barrel exactly so the crimp grips every strand, and the stud size should match your terminal so the lug sits flat and tight.

A bellmouth lug has a flared, funnel-shaped barrel entry. It makes it easy to insert fine-stranded flexible cable, which tends to splay after stripping, without strands catching outside the barrel. A standard (straight barrel) lug has a plain entry and suits regular stranded cable.

Use a lug crimper sized for the cable, such as a hexagonal or indent crimping tool. Hex crimpers give an even, all-round compression that suits tinned copper lugs. Hammer crimpers and pliers give inconsistent crimps that can heat up under high current.

Tin plating protects the copper from oxidation and corrosion, keeping a low-resistance connection over time. It is especially useful in damp, salty or high-humidity environments such as caravans, boats and outdoor battery boxes.

A circuit breaker lug has a narrower palm than a standard cable lug, so it fits the tight terminals on circuit breakers, isolators and compact switchgear. Use one when a standard lug palm is too wide for the terminal or would sit too close to the next pole. Match the cable size (mm²) and the stud size just like a standard lug.
