   I bought a 12volt 8.5amp TDK Lambda power supply from Radio Spares to   
   replace a Mean Well 12v 8.5a supply which had failed after 3 years.

   I connected it up to a 3 pin plug with a 13A fuse. When I plugged it in   
   to an extension socket, which had a 13amp fuse, to check the output   
   voltage, it tripped the CU , and the said extension socket blew the fuse.   
   Any ideas as to why.   
      
   Thanks
