Is there something wrong with you?monte86 said:Not what I asked, obviously you don't know.
We're not trying to make you look like a pratt - but nobody here had any chance of answering your question because you were completely unable to provide an absolutely vital piece of information - namely the size of your existing cable. Did you really expect that your question could be answered without knowing that? If so, one might observe that we had no need to try and make you look like a pratt...monte86 said:I am not an electrician, obviously all you guys are and understand the workings of the system. If you ask me something about my job, I could also make you look a pratt, no problem.
Take it back - you can always buy again once you know what load your cable can take.May I also add that I will not be doing this job myself, I will be employing a professional gentleman to do it for me. The reason for my question was, my wife purchased a new shower from Homebase and the rating of the unit is 9.5kw, different to what we have at the moment. She needs to return it within 28 days to exchange or refund.
Sensible - they have no way of knowing either.Homebase told her it should be okay, I am not so sure.
We don't know. Nobody in the world can know without you telling them, or them looking to see, what the current cable is.The wiring installed is compatable with a 7.5kw shower, and is buried under floorboards and in walls and very difficult to get at, hence the original question, can it just be replaced without changing the wiring.
I think so too, but as a favour, please try the following: Phone a few "qualified persons" and ask them to give you an answer over the phone. If they ask what the existing cable is say you don't know, and if they say that they need to come and look tell them that you want them to answer the question without doing that.I think my best bet would be to get the advise of a qualified person.
monte86 said:Already done that. I was asked how long I have had the shower, what type of fuse, I had in the fuse box etc. I was informed that would have at leased a 6mm cable running from the fuse box to the shower using a 7.5kw unit using a 40amp fuse. To use the 9.5kw unit I would need to use the regulation 10mm cable, or I could drop the fuse to 32amp to protect the wiring, but the shower may cut out if used for a long periods. I think I would be safer to take the shower back for a refund, as everybody I ask has a different answer. Thanks anyway for your help.
