With reference to your E/Cl/T16.4.20 in which you are taking up the suggestion that a flexible connection could be made to earth the condenser housing, could you also consider a proper brush being fixed between the governor case and the make and break, casing, i.e. at the part of your diagram marked "making contact surface". As previously pointed out, we have had failures owing to the faulty earthing of the condenser housing itself, and although this condenser housing may be earthed with the flexible, the ordinary primary circuit may not be complete owing to the moving contact surface above referred to, also the faulty contact between the condenser housing and the contact breaker casing.
