MK Electric metal consumer units are fully compliant with BS 7671 (2015), including Amendment 3 (effective July 2015).
​The Sentry range of Consumer Units from MK Electric has been stylishly designed to blend in with its environment. The curved lines and slim-line appearance mean it won’t look out of place when installed in hallways, lounges or kitchens.

The MK Sentry metal consumer unit portfolio has a stronger, more robust design.  It features a top hinged door which prevents the door being left open after use which is a possible fire risk. The units also include sealed side holes to ensure total containment, reducing the available space for fire to escape.

The new range incorporates features to aid in ease of installation, saving both time and money, including the incorporation of a supporting Din Rail “T” Bar to Support the weight of devices on the DIN rail without twisting or bowing and three additional extra large feed holes for greater flexibility of wiring, especially in retrofit installations.

The consumer units also benefit from continual earthing which means you only need to earth once via the base as the door is earthed through the hinges. The unit is supplied with
