Reduced low voltage 110V 16A socket circuits

Electron666
Hi, I have been asked to provide 110V 16A sockets within a college workshop. The client is unable to advise of any equipment or loads that may be used and I am unsure of how many sockets to connect on a single circuit. I assume power tools will be connected for intermittent use. Does 2No. 110V 16A sockets on 1No. 20A Type C MCB radial circuit sound appropriate?....could you connect more on 1No. circuit, say 4No?....or would you provide 1No. 16A Type C MCB radial circuit per 110V 16A socket.

Thanks

    How may sockets have you been asked to fit and where - all side by side or dotted about the room, as if for machines.

    I'd be very wary of a client that has 'no idea' why they want the sockets; I bet someone does, because someone will have asked for them, and you need their input if they are not to be in the wrong place or in some other way inadequate.

    Generally you do not want more than a 20A breaker feeding circuits with 16A sockets, and if you do not know the load you should probably cost to cable it as if there are no more than 2 sockets pre breaker, just so that things do not trip off, and 2.5mm is not a bad size cable to work with. However, as above, the total load will be limited by the source of 110V.
