Does the 554C4 have new 4 single screw connectors instead of the original two screw connectors?

Over the coming months, the terminal connectors supplied with a number of Electrical Accessories will be changing. These changes are:
 
  1. The screw type in the connector will suit either a No. 2 Philips Drive or a No 1 Square Drive screwdriver.
 
  1. Terminal connectors will now be square wrapper design, ensuring reliable connection.
 
  1. All connectors will now be supplied with single screw. This is fully compliant with AS/NZS3000:2007 as per clause (d) below from sub-section 2.9.4. for active, neutral and earth connections.
(d) a neutral conductor used as a combined protective earthing and neutral (PEN) conductor for protective earthing of any portion of an electrical installation, the terminal shall be of a type having—
  1. two screws; or
  2. one screw with an outside diameter not less than 80% of the tunnel diameter.
 
The terminal connectors being supplied have a screw diameter in excess of 80% of the tunnel diameter which means the single screw connectors can be used for active, neutral and earth connections.
