How do you know that? This is a 10mm² cable, its nominal rating is 64A. How can you possibly say that a separate hob and oven will overload it? If this was a single cooking appliance, i.e. a freestanding electric cooker, the diversity calculations would allow you to connect one of up to 39kW (39kW = 170A, 10+(160 x 0.3)+5 = 63). Also, what possible justification do you have for saying that overloading it will cause a fire? Do you have some knowledge of the size of MCB protecting this 10mm² cable? Is it well over 100A or something? Putting out ludicrous and stupid scare answers like that doesn't help.breezer said:you are not allowed to do what you are trying to do, you will overload the cable and cause a fire,
What is an oven + a hob, if not a cooker? If I bought an electric cooker, consisting of an oven and a hob and one set of terminals, got out my trusty hacksaw and wire cutters, and turned it into two appliances, why would it suddenly take any more current than before?andrew2022 said:yes, it is a no-no
the circuit is designed for a cooker ONLY. add anything else and itll overload the circuit and constantly trip the breaker
Diversity calculations are one thing - ratings are another. Are the socket outlets on CCUs rated at less than 13A? Everybody who makes/sells them describes them as "13A".breezer said:you obviously do not understand since you have to ask, but i shall explain.
diversity allows 5A MAX for the socket, NO MORE, its for plugging in things like extractor hood, electric knife , electric tin opener
WHY??breezer said:shavvy said:And what is so wrong with connecting the hob to to the dedicated cooker curcuit
nothing, so long as it is just the hob on its own, which is not what this post started as, the poster wanted to connect the oven AND hob to the cooker cct, which is a no, no
It was just a demo that ryanj did to show that you can get 2 x 10mm² into one terminal.notb665 said:In the shed lovers picture above, why is the phase and return in the same block?
Ah - so not cables catching fire, then....breezer said:the reason i said no is the way he wants there is no sepeate isolation or cct protection
Do integrated electric cookers have internal fuse(s) for the oven(s), or are they quite happy with the 40-50A MCB protecting the 10mm² cable supplying the one appliance?the other thing, assuming as most are the oven, if less than 3 kw how is he going to protect that, cant put it on 10mm cable with hob, it has only hob size fuse/ mcb.
No - but you can get 1 in:you cant put it via an fcu becuse you physically cant get 2 10mm cables in an fcu.
