The New Macey 300 Amp Lockable Cover is designed to provide both physical protection and a practical lock-out point for high-current plug and receptacle connections. In underground mining environments where connectors are frequently exposed to impact, dust, moisture and rough handling, protecting the interface is essential for long-term reliability.

During cable handling, transport and storage, the cover helps shield the connection face and sealing surfaces from damage and contamination. This reduces the risk of debris ingress and protects the electrical interface, supporting consistent coupling performance and reducing avoidable maintenance issues.

As an isolation control point, the lockable design supports site lock-out/tag-out procedures by allowing operators to apply their own padlock. This provides a clear visual indicator of isolation and helps prevent unintended re-energisation during inspection or maintenance activities.
