[QUOTE="apprentice87, post: 440337, member: 13534"] Hi All, Anyone know what type of fuses will be in a 200A cutout like the one pictured below?? I know they are 100A ones, but i need to know what type if possible so i can find suitable fuse that will discriminate with the cutout ones. At present the switchfuse protecting the submain has 200 amp fuses in it and then they wonder why the cutout fuses blew first.. [ATTACH]7893[/ATTACH] Second question; See the earth terminal on the side of the cutout. How do i know if the DNO have linked it to the neutral and the supply is TNCS, or whether it is just a convenient place to fit a connection to the cable sheath, and the supply is TNS ??? Myself, i would have though a voltmeter between the earth terminal and neutral and see if there is a PD between the two... john.. [/QUOTE]
