110V 16A sockets in a ring arrangement

I am planning to make a 110v circuit containing up to 10 x 16A 110V single sockets. The circuit is up to 100m long. Is 32A MCB type C and H07 4mm2 will be ok for it or I need to take into consideration of using RCBO instead and calculate voltage drop to size required cable properly?

  • From an entirely practical point of view - do you have any control of what will be plugged in to the sockets and how many start/stops might happen? 

    I have at least one 110V 16A extension lead that is probably 50m long. 1.5mm three core yellow flex.

    All to often I have had a clever wally connect his large chop saw to a 110V lighting circuit (Often 110V work stand lights will come with two 16A 110V sockets on them) with the intension of doing hundreds of chop saw start/stops per day, and then is surprised when it trips the lighting circuit or melts the lighting cables if the lights are plugged into larger overcurrent protection. 

    All too often I have seen melted 110V cables because of 110V machinery start/stopping or a 110V  floor sander. People will take off a 32Amp for a 16Amp to make it work. I do understand that the thinking that a 32Amp should protect the 4mm circuit, but not the extension lead or the actual plug socket its self. (fire is the risk I'm most concerned about here)
