Power terminal lug for 50mm cable hole 8 – code: 14.035.50 – Osculati

Power cable lug for 50 mm² cable with 8 mm hole (Osculati 14.035.50)

I power terminals Osculati are designed to create neat and reliable terminations on large section cables, typical of onboard electrical systems and installations where power connections are present. This model is dedicated to 50 mm² cable and features 8 mm hole, for fastening on compatible bolts/terminals.

The construction is in high conductivity tinned copper, a common choice in nautical and plant engineering to achieve a clean connection and good durability over time in demanding environments. The result is a component suitable for maintenance and wiring, with a practical format for installation on batteries, battery switches, busbars, and distribution points.

Features and construction details

Material

The terminal is made of tinned copper and indicated as with high conductivity. Tin plating is a finish typically used to protect the copper surface and promote a more stable connection over time, especially in contexts where humidity and salt spray may be present.

Cable section

Version for 50 mm² cable section. It is important to select the correct section to achieve proper crimping and tightening consistent with the conductor diameter.

Fixing hole

The product is identified as 8 mm hole. When choosing, check compatibility with the diameter of the pin/bolt of the connection point (for example on busbar or terminal).

Dimensions (available data)

For this variant, the following measurements are available from the data:

• D3: 20 mm
• L: 53 mm
• D4: 8.3 mm
• D2: 9.5 mm
• D1: 13 mm

Note: the dimensional codes (D1, D2, D3, D4, L) are reported as in the original datasheet and may refer to diameters/clearances of the lug and the overall length. In case of doubt, compare the measurements with the available space in your panel or connection point.

Codes and identification

• Manufacturer/Supplier: Osculati S.r.l.
• Supplier product code: 14.035.50

Typical applications (nautical and plant engineering)

This cable lug is suitable for work and maintenance on power wiring where a ring termination is required. In nautical and technical fields, it can be used, for example, in:

• connections on and for managing the main connections of the electrical system. In a nautical context, it can be used in many operational situations, for example on pleasure boats or technical installations where an orderly and easily recognizable connection is required. and related distribution points;
• connections to battery disconnects and switching devices;
• wiring towards busbars and power terminal blocks;
• making cable runs with ring terminations in panels and technical compartments.

The choice of section (50 mm²) and hole (8) allows aligning the component with the wiring requirements and available bolts, reducing adaptations and improvised solutions.

Practical advantages

• Neat connection: The eyelet facilitates a clean fastening on pins and bolts, with stable tightening.
• Material suitable for technical contexts: the tinned copper It is a common choice for wiring in environments where conductor surface protection is important.
• Targeted selection: Variant dedicated to 50 mm² with 8 mm hole, useful when you want to maintain consistency between cable, terminal lug, and connection point.
• Maintenance support: Component suitable for repairs and refurbishments of worn or oxidized terminals, maintaining a professional wiring setup.

Usage and installation notes

Crimping

For correct assembly, it is advisable to use a tool suitable for crimping power terminal lugs. The original datasheet indicates a tool reference:

• Tool to fix terminal lugs on electrical cables: 14.035.30

Ensure that the crimping is performed with equipment appropriate for the cable section and that the conductor is correctly inserted into the terminal lug body before pressing.

Cable preparation

• Strip the cable cleanly, avoiding damage to the strands.
• Fully insert the conductor into the terminal lug before crimping.
• Check that the eyelet rests properly on the fastening point and that there are no interferences with other components.

Final checks

After installation, check the mechanical tightening at the connection point and the wiring order. In power applications, a well-executed termination helps keep the system cleaner and easier to inspect during maintenance.

Important note

Final compatibility depends on cable section, conductor type, crimping tool, and fastening point geometry. If you are replacing an existing terminal, always compare the hole and dimensions with the removed component.
