On a solar farm we have an supplementary bonding from the PV tracker TCU motor to the Pile. It is a flexi breaded earth that has a black plastic insulation over it for UV protection and corrosion. We have a consultant that picked this up as non compliant with the regs and wants this to be re- sleeved to a yellow and green ID. My question is the regs state that on a bare conductors you only have to sleeve the ends or at certain sections with yellow and green ID markings, but its wording is the following: ".....by the application of tape, sleeve, disc, or paint. " what is the disc they are talking about, is that the do not remove earth tag we can install rather than to resleeve the earth??
