unless you can find the ends and theres no way of ensuring they dont conrtol anything leave well alone I was on a site a couple of years ago everything was being removed even fixings to walls,celings the main contractors spark killed everyting out the board but there was a feed to another bit of the building coming from the DNO transformer the demolition guys were given the all clear to cut cables out except the well marked mains they proceeded untill everything went dark in the other building ( magor bank head office) as the bunch of pyros made dead by spark contained the EM for the DNO Transformer An expensive lesson was learned that day ie start at one end of cable and strip out dont just stick a hacksaw through a big bunch
