Each AC and DC TPA switchboard is designed to your requirements by our highly experienced marine electrical system engineers. They will work with you to ensure the TPA switchboard will have the level automation that your yacht needs as well as being certified for the classification society of your choice. Any special requirements can be accommodated and the switchboards are available in a variety of cabinet sizes suitable for any yacht arrangement.

TPA switchboards can be designed to meet all marine classification agency requirements including ABS, Lloyd’s, DNV, RINA and BV. The certification is taken care of by our engineers and the switchboard is supplied with a complete set of stamped drawings.
