hi can some one please anser this for me. i have used a over haed catinary to support a 1mm t&e i have ran a sperate 6mm earth and connected it to the catenary, it is metal so it must be earthed, what size earth should i have used to earth the catenary wire. thanks
 
hmm, not sure but although 6mm should be adequate, I would have probably stuck in 10mm earth same as an earth rod or main bonding just to b safe
 
if the catenary wire needed earthing then what would it be classed as ,personally i'd just put in same size as gas or water (main equipotential bonding)
