This protects the downsizing of cable as you suggest with regard to current carrying capacity. Technically it is ok to use 1. I always install a minimum of 2. If the 1. RF Lighting , 13 Jul The method that has been used is free air I suppose, it runs down the back of kitchen units then approx 3metres along the floor and into a double socket.
I could likely replace it without too much trouble. It is the supply for a washing machine and fridge. JohnD , 13 Jul Joined: 3 Sep Country:.

The cable is made up of 3 solid cores, which are individually insulated and wrapped in an outer PVC sleeving.
The colours of these cores are brown, black and grey, with a bare earth core to be insulated with green and yellow sleeving. For outside use, Steel Wired Armoured SWA cable is used to move power underneath the ground by burying the cable, or overhead using a catenary wire. The number of cores within the cable can range from two to four, depending on the purpose.
The cable is formed up of these inner cores, which are each individually sleeved, then wrapped up together with a layer of plastic sleeving, which is then covered with a layer of protected wire armour, before finishing with a final outer layer. Due to the multiple layers of protection, the cabling is known to not be as flexible as some other options. If you require a greater flexibility for your connections, then an alternative outside cabling option is Arctic Flex, which is covered below.
Most of your portable electrical appliances and light pendants will use flex cables, as it allows for flexible connections to the power point. The cable is formed in a cross section, normally with 2 or 3 cores insides a PVC outer sleeve coating. Flex cables allow you to get a greater bend, compared to other cables, and also straighten out with ease. If it is flex, then you really need the RCD at the house end, as if you cut through the cable with your spade, you are going to get a good belt off it.
Has the switch inside the house got a fuse in it? Something like this? If so, and it comes from the socket circuit in the house, then 1. The main rcd could still trip. You may find the main board will trip anyway. First, confirm that the switch is on a socket circuit or something appropriately sized.
