I am going to rewire my house and at present we have no earth wire anywhere in our house. Even the wires/cables available here in the market only have one phase wire and one neutral wire in them. So I am going to take an earth wire from the distribution box (which I am going to have installed) to all the outlets in our home. I have two questions:
Q1: Can we connect the earth wire with the motor water pump in our house? The motor pipe go more than 150 ft underground right down to the water. Will it be safe? Our motor pump is like this except that this is a hand-use water pump and we have an electric one at home:
Q2: Suppose the earth wire from the main panel is connected to one outlet (with its earth pin). Now to connect the second outlet with the earth wire, can we connect its earth pin with the previous outlet's earth pin?
I am from Pakistan and here we have 220-240 single phase wire and one neutral wire to the meter.
