Ceeform 32A OCPD rating?

vantech

Hi, 

What size MCB should be used for a 32A industrial ceeform socket? 

The appliance I am looking at comes with a 32A plug, with the device (an EV) itself pulling 31A of power continuously. The device is an Ohme charger, as per the below link:

I generally try to load MCBs to a maximum of 80% of their capacity, therefore the suitable choice for the 32A socket outlet would be a 40A MCB. 

The ceeform has no built in fuse, like a 13a socket so in theory, the socket could be overloaded if used in conjunction with a bunch of splitters and extension leads. 

Thoughts? I’m sure the regs state something about 16A sockets protected by 20A MCBs, but I am unsure about 32A. 
 

Thanks.

    What makes you think that a 32A socket cannot have a 32A breaker, which will take an hour to trip at 40A? Why are you trying to change the intent of BS7671? Your 80% is completely odd, where does it come from?
