WTPNEB14 is a 14-module 3 phase extension board designed for use within the Whitecliffe WTPN range. It provides a practical way to expand circuit capacity on existing 125A three-phase distribution systems without replacing the main board.

Built in a robust 1.2mm steel enclosure, this extension board is suited to commercial, industrial, and larger domestic installations where extra outgoing ways are needed. It accepts our 6kA devices without modification or additional hardware, helping keep system expansion straightforward and consistent with the wider WTPN board range.
