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

 

[mike]

ok thanks for that mate

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)
