I believe I have been wrongly advised by my supplier about sizing cable for a lighting installation and I was hoping that someone with more experience of DC cabling will be able to set me straight.
We are looking to install some LED strips to a coffered ceiling above a swimming pool.
I have specified 24V as the length is 15.5m (x2) by 4m (x2) and the strip is 5W per metre
We are going to treat each length seperately; 2 x 15.5 and 2 x 4m with their own power supplies
However, I dont want to take the 230V into the pool ceiling area and so I've wired 1.5/1.0 twin + cpc from the power supplies to the end of the strip. This length could be 30m as there are only 2 accessible points around the pool. In doing a quick calc its showing that I might need a 10mm cable??? Is this correct?
If this is so, I will have to take the power supplies into the pool area, but there are maintenance issues as well as being cautious with 230V above a pool
Thanks
