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: 

https://ohme.odoo.com/shop/ohme0402gb001-ohme-go-commando-to-type-2-uk-5

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.

    Is there a reason for not using a Mode 3 charger? 

    Client has purchased one of these with a Ceeform 32A plug. 

    Could be a lot of hassle for you depending on location and earthing arrangements. As to protective device 32amp 

    Indeed.

    Earthing is an interesting subject as many EV users have 13amp jobbies which they plug into their 4 gang extension leads without a thought! These don’t take earthing arrangements into account.
