Been asked to look at local pub kitchen as a circuit was tripping.
The circuit appears to be a repurposed cooker circuit, fed in 6mm t&e to two MK double sockets. Second socket is fed in 2.5 from the first.
The load is 2x twin fryers… at 2.6kW per unit… so 4 units, but only 3 are ever used as the last one is positioned under a shelf.
The RCBO is only a 20A…. But I don’t know if that’s a case of “all that was in the van at the time” or a purposeful decision considering the load. Ie keeping the load limited to protect the sockets themselves.
I think it would be ok to uprate to a 32A…. And change that little bit of 2.5 to 4.0mm
The MK sockets are the older type, so not the newer less quality ones.
