Guys,
Am just doing some decorating and changing some units in my kitchen and have come across something that I can't quite get my head around. I'll do my best to explain this logically.
I'll start by giving some background of how things are set out. The house is approximately 5 years old. The kitchen has electric cooker and induction hob as provided when the house was new. For cooker isolation, there is a switched cooker unit above the worktop with socket outlet. For hob isolation there is a double gang module plate with switches and fuses for the hob and extractor fan.
One of the changes I am making is to add a pan drawer under the cooker. While pulling the oven out, I have discovered that the hob is not connected to the outlet which is isolated by the labelled hob switch, if that makes sense.
Behind the cooker there are 3 outlets. One is a socket which is isolated by the cooker switch, which the cooker is plugged in to. Another is a connection unit for large area cables, also isolated by the cooker switch and has the hob connected to it. The final one is a connection unit isolated by the hob switch.
The two which are isolated by the cooker switch are both supplied with what appears to be at least 6mm2 cable. The feed from the hob switch is by the looks of things 1.5mm2, definitely smaller than 2.5mm2 anyway!
My question is, is this set up acceptable? The cooker is rated at 2.8kW and the hob at 7.2kW (2x 2.2kW rings and 2x 1.2kW rings) so a total of 10kW (which I'm guessing is when everything is on max). Now my knowledge is a bit rusty but I seem to remember that 6mm2 probably wouldn't suffice for 10kW? Am I correct? Is the assumption made that not everything would be on full power at the same time though? The circuit is protected by a 32A RCD. I am certainly thinking that the hob shouldn't be connected to the feed that is 1.5mm2 (or possibly less I'm now thinking looking at it again!).
If everything is actually OK with the current set up, with both cooker and hob connected to the same feed and the labelled hob feed not used, do I need to make it clear that the labelled hob switch does not actually isolate it? I would hope that someone would check it was properly isolated before disconnecting it but you never know.
To add to the situation, the property is going to be rented out in the next few months as I am being posted abroad. I obviously will be getting an electrician in for full inspection and testing but would just like to know if it's worth leaving the cooker out or not until that happens.
I look forward to your views!
Thanks in advance.
