Just discovered that my electric fire (2kw) power supply is taken from a socket on my downstairs ring main. It goes though an FCU and then to the fire is this safe. There is also a 2nd FCU off the FCU that I was going to use to power a wall mounted TV but now don't know if it is safe to do so. So ring main to FCU then fire. With a 2nd FCU of the other FCU to a TV is this safe. Just moved into house a year ago so still discovering things that need putting right....Please help....
