110V 16A sockets in a ring arrangement

Tom D

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?

    "Internally fused " 110 volt 16 amp sockets are most unusual and would probably be custom made. 16 amp sockets of any voltage should not in my view be installed on an OCPD . larger than 20 amps, Fuses would be needed in BOTH poles of a circuit supplied from an isolating transformer with an earthed center tap. Or two pole MCBs

    you do get unfused things like this in theatre and events/ concert land, an unfused 32 to 16A split, but the assumption is that the person using them is at least part skilled and installs things in a way that the load at the far end is well defined and limits the potential for overload. Generally 16A sockets on a 32A supply for unskilled use is not wise.
