What is the MF logo?
The MF logo was introduced in BS5733:2010 "General Requirements for electrical accessories" as a marking that can be used on accessories to indicate that the accessory doesn't require further inspection, testing or maintenance after installation
Does the Wagobox have the MF mark?
Yes. From October 2012 you will be able to purchase the Wagobox with the BS5733 MF mark. The new Wagobox will be supplied with an extended set of installation instructions that will explain how the Wagobox and the Wago 773 and 222 terminals can be used together to construct a BS5733 Maintenance Free accessory
