All incoming from tnb need to use 230v for calculation. Tnv officially supply 230v no longer 240v
I will use 220v for calculation, because the incoming always have variance. Is best to over spec than having problem later.
Career26,
Sorry to step on the brakes to back track. You raise a very pertinent point and point 3 here raise some misgivings I have concerning putting the cart before the horse.
To clarify: this place of yours how recent is the development? If in pre-2004, I hazard a guess that they planned for gas cooking using 60cm or domino hob style. If later or was renovated before and has an induction/heat plate/vitroceramic hob before chances are high wattage wiring is in place.
Otherwise to assume the worst, all electrical is shared off a single 13A or 15A line for fridge, hood and other electrical appliances like kettle, toaster, microwave. At best it's two lines 13A and 15A. Even better if provision was made for electrical cooking is 13A and 20-25A.
If it's an old place, I'm guessing that by buying such a hob, that you'll be doing some form of renovation including adding high amp (20A at least) electrical wiring for this purpose. Hence the rest of this is based on this assumption.
If adding electrical point is not considered as part of the renovation, I recommend revisiting the core assumptions above. You can enlist an electrician help do a sanity check.
Low wattage means less than 4800W (20A or 4800/240)? That means it needs a separate dedicated apart from fridge, hood. Because if the development is older than 1990s, chances are unless there was previous renovation (with an electrical hob evident), no one in those days would foresee the possibility cooking with electricity and chances are they have only one 13A point in the kitchen or at best one 13A or one 15A.
Not that I want to spoil your renovation journey but by knowing this in itself beforehand is to be sure that we know where you stand and don't give advice in a misleading manner. Not a problem if the electricals are known - I assume here that by saying low wattage there's something in mind between 15A to 20A. But if you don't yet know, better to sort that out first then you can see for sure what options lies before you.
