Hi all,
I live in a newesh built small house (7 years old) and recently had a gas leak on the pipe running under the kitchen floor (concrete) to the gas hob.
The easiest option was to isolate that supply and go for electric. My kitchen has a ccu with socket to the left of the hob and protected by a 32amp MCB at the consumer unit. This currently supplies the oven (single oven max 3kw)
To the right of the hob is another CCU without socket is a 32amp mk double pole switch marked 'HOB', runs on it's own radial back to the consumer unit and also protected by a 32amp MCB.
Without assuming anything, after removal of the gas hob and electric oven, I checked the cable diameter at both CCU's and at the consumer unit to see if they are the same thickness and is either 4mm or 6mm T&E.
The connection plate behind the oven is a typcial cooker cable connection plate, however the hob outlet also behind the oven is a 13amp unswitched single socket, without seeing the original specs or speaking to the electrician who wired the house, I assume that as this supply outlet has a single socket attached is because it is only for the gas hob ignition, which has a 13amp plug moulded on with a 3amp fuse, and therefore needs much lower protection than the 32amp supply. I can easily change the single unswitched socket to a Cooker cable outlet plate for the hob. The cable thickness from the 'HOB' 32amp DP switch to the single socket is also the same as that used for the circuit back to the consumer unit and the same as that used for the oven radial.
I wouldn't normally be this nervous, but after a gas leak, you do get a tad concerned about safety.
I consulted a retired electrician friend who said it was either 4 or 6mm.
The query I have, is the hob is rated at 6.5kw and if my sums are correct means that at full load, is rated at 28-29amps, so in my mind either circuit will handle this just fine, however, I cannot actually see what the cable really is, as there is no visible length anywhere to see the writing on it.
All I can say is that it has 7 copper strands for each conductor and the earth is single stranded, which lends me to believe that it is either 4mm or 6mm.
I looked at TLC's cable sizes for overall dimensions and the cable I have size wise, is in between the 4mm and the 6mm at about 12.5mm wide.
So, if in the worst case scenario, it is 4mm T&E, (which I would be very surprised at as it has been used for both oven and hob supply) would the circuit take the load for the hob?
The distance between the hob and the consumer unit is max 9 metres.
Thanks
