Collective thoughts about issue… Pub kitchen

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.

Ideally they should be on their own circuits and not terminated into plug tops.

Is it instant trip or thermal.

In kitchens they are normally on one gang sockets.

They normally come with moulded 13A plugs.

I did say Ideally as they are over 2kw.

yes.. theyve got moulded plugs on them.

Ideally, everything would be on its own circuit, but as pub kitchen, its grown over the years... adding more and more equipment into a room as menu choices increase.


We are allowed to run a 32A radial circuit in 4mm instead of a 2.5 rfc..... but that doesnt take into account what is being plugged in.



I got the usual "but its worked fine for over a year"..... and "when it trips, we just plug into the other sockets..."

The other sockets.... which are running a couple of freezers, a pizza oven, eye level grill, kettle, microwave....



In the meantime, ive told them to only plug in 2, and use 1 in each double socket.....
