BS5733 Maintenance Free Wagobox
We are delighted to announce that the Wagobox junction box soon be available with the BS5733 MF mark. 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. Since the 1st of January 2012 the MF mark has become a requirement for maintenance free accessories and we have been working hard with Wago, the manufacturer of the 773 and 222 terminals, to complete all the required analysis, testing and product upgrades to ensure the Wagobox can be used as a maintenance free accessory in accordance with requirements of BS5733. This work has been completed and the new Wagobox with the BS5733 MF mark will be available in October 2012. Apart from the additional product marking, the new Wagobox has a lid locking mechanism and will be supplied with an enhanced set of user instructions. For further information please visit the Wagobox support page at Advice and support where we have posted a Question and Answer document in the FAQ section. If you have any further queries then please do call and we will be happy to answer your questions.
