16mm tails on 3phase

[TJC1]

Evening all

Guy who owns a small industrial unit currently has 100amp 3phase

At the moment he only have a single phase baord with feeds a few lights and sockets. He wants to install a 20a 3phase supply for a something

The mem 20a 3phase switch fuse i got only allows upto 16mm tails and not 25mm. Would using 16mm tails be ok for 100amp supply? The power being drawn wont exceed 20amp so i cant see the issue

I would be most surprised if 16mm conductors fit a MEM switch fuse.

Regardless of whether or not the tails will fit in the switch fuse it is fine as the 20A fuses will provide upstream protection of the tails. In theory you could use any tails rated above 20A.
