What size

[9regnac]

What size of fuses would you put in a TP&N switchfuse which is controlling a 16a TP&E socket outlet?

Is this a serious question?

Im learning

It would just be 16a fuses required

Its in a college both dont get told whats its supply

What size is the cable, how is it run, what is it run in. As it's a 3 phase socket is a specified piece of equipment going to be plugged into it?

Is it fuses you are going to use or some other protection device. If it is fuses then you have to bring into account rating factors when sizing the cable ie a BS 3036 fuse will be 0.75.

Rule of thumb though 20 amp would be my maximum for just a 16amp socket.

 

[telectrix]

the fuse size is determined by the cable it's protecting.e.g. 2.5mm. the type depends on the type of load, e.g. motor etc.
