Large-Scale Power Distribution Panel for Marine Survey Vessel Support Equipment

DelaControl engineered and manufactured a five-section power  distribution panel built to IP54, designed to DelaControl's standard  practices and compliant with BS EN 60204, BS EN 61439-1, and BS EN  61439-2. The panel was sized to fit within the container height  constraint, with a plinth arrangement to facilitate bottom cable entry.  All low-voltage control gear and circuit protective devices were Siemens  throughout, and all metalwork was powder coat painted to RAL 7035.

The  two main 800A incomer sections each incorporated Siemens 800A switch  disconnectors, Sifam Tinsley current transformers, and Schneider PM5310  power monitoring meters mounted on the panel front. Outgoing circuits  across all sections were protected by a combination of Siemens SENTRON  moulded case circuit breakers and Siemens miniature circuit breakers  rated appropriately for each load, ranging from 16A to 400A. The  sub-distribution sections used Schneider comb busbars with individual  MCB-protected outgoing ways, while solid copper busbar and nVent Eriflex  components formed the internal power distribution backbone.

Full  electrical design was produced in EPlan, with drawings supplied in both  native and PDF formats. A Declaration of Conformity, signed inspection  and test certificate (including torque verification records), and  thermal calculations produced using Rittal Therm software were all  provided as part of the documentation package. Pre-delivery testing was  carried out at DelaControl's Bristol facility prior to delivery.
