I'm getting a shock when I touch walls, electrical equipment like a water cooler, fridge, etc in my home. I have followed this procedure as I only have a DMM with me.
The readings I got after checking with DMM are: L-N: 249.2 V L-E: 255.5 V N-E: 14.5 V
As mentioned in this procedure, theoretically voltage difference between neutral and earth will be zero and considered as proper earthing, but practically it will be 2 to 4 AC volts. Whereas, in my case, I'm getting around 14.5VAC which is significantly high. Hence, I may be getting shock in my home appliances.
Please help me in identifying and rectifying the issue!!
