No earth

[ohthatshowyoudo]

Hi please can someone assist me.. i have started an inspection on a control circuit and noticed they have not run in an earth on a control circuit they run in a 3 core cable but taped up the green and yellow as live cable. the cable is run under ground from the distribution and is terminated within enclosed plastic houseing so there would be no fault on caseing. please can someone explain to me how i go about protecting this sort of circuit.... or does it require rewire ?

I agree Malcolm. 3 wire stop/start control? If so, is it wired in flex, what cca? length of run? what mechanical protection underground?.
