David Hello! Open slots or is ok if you have to fixing means (such as bolt and lock washer) for the connection. This is similar to fork type crimp connectors which have been acceptable by UL,TUV and other test agencies. Please note that some test agencies including UL and TUV do not like the fork type connections if relied upon for earthing and/or earth bonding connections. You may wish to discuss with these agencies when you use an open-slot connection for earthing/bonding connections. Best Wishes,

This decision was taken to make installation and maintenance easier. However, their installation Manager has objected to this without giving a reason. I have e-mailed my contacts within TUV and UL, and after some 48 hours they have not responded. Are there any sufficiently knowledgeable people who can tell me whether or not this is permissible, and why. Best regards, David Sproul.
