A 400A three-phase power system provides the capacity required for large-scale temporary electrical installations, helping production teams supply substantial lighting, audio, AV and other compatible production equipment. The Powerlock connection system also provides a practical way to integrate the unit into a wider professional event power network.
For event hire, reliable high-capacity power distribution is essential. The Rubber Box Powerlock Master can form part of a professionally designed temporary power system, helping production teams manage significant electrical loads and distribute power efficiently across stages, venues and event sites. Its professional construction makes it well suited to demanding production environments where equipment is repeatedly transported and deployed.
The Rubber Box 400A 415V Powerlock Master is therefore an excellent choice for professional event power hire where substantial electrical capacity is required. Whether supporting a major concert, festival, touring production or large corporate event, it can provide an important part of the infrastructure for a properly designed high-capacity power system. All Powerlock connections and high-capacity electrical installations should be designed, checked and operated by suitably competent personnel in accordance with applicable UK electrical safety requirements.
