Ideally in the range of 5oMohms is required for less
leakage current.2Mohms per KV of the cable at room
temperature is a thumb rule

why we use the fuse in only one wire? althrough in ac current the current flows in both directions. why the neutral wire can be taken half the magnitude of phase wire while same current returns from neutral wire?
