got a query regarding my electrics, I have a cable that is open ended at the moment and is waiting to recieve my under floor heating and leads back to my RCD board, If that one fuse is isolted at the board but the rest of the board is live would I still be getting a current in this cable? I know this seems a silly question????? thanks in advance!!!!!!! TelJol. :?[color=black][/color]
If the breaker/Fuse that is supplying that cable is removed or in the open position, there should be no current being offered to that cable via the CU.
You should always test the circuit is dead before you try anything though!
Hi, if the reason for asking is because a neon tester/voltmeter shows live it's probably due to induced voltage. Cables running together for a distance say leaving consumer unit can 'couple', there will be no real power there but is why it's recommended to put all 3 cores in 1 connector at load end until needed, likewise any unused cores in a multicore cable should be connected to earth not left 'floating',
