The Wylex NMRS44206 all metal consumer unit is fully compliant with Amendment 3 to BS 7671:2008. A twin RCD high integrity split load 2 + 4 + 4 fixed busbar configuration protecting two banks of four MCBs the unit is supplied with 100A switch isolator and 2 x 80A 30mA RCDs.

The NMRS44206 high integrity consumer unit works by using three busbars instead of one. One busbar for each of the RCDs and one for the main switch. They are connected via fly leads such that the main switch is still used to isolate the entire board. Consequently, a High Integrity consumer unit allows you to protect all your mission critical circuits, such as smoke alarms, security system, fridge freezer etc. through the use of RCBOs independently.

The metal enclosure comes supplied with a full metal DIN rail and full complement of earth and neutral terminals along with circuit identification labels providing clear understanding of outgoing ways.
