HI, I’m sitting with a problem where people shock when they use the shower, especially when they touches the warm water tap. The Continuity of the earth system is 0.2 ohms, the insulation resistance test reading is infinitive.
It is a three phases system.The Municipality already supply a separate earth cable but the people still shock. The shock is not that intense, but they feel the static especially when they got a cut on their fingers.I tested the system with wet hands but everything seems to be ok but when they shower they feel the shock.This happened greatly on the warm water tap.
What can be the problem.I appreciate your input on earthing.Thanks
