I agree: SELV as a low-voltage earth-free supply is not actually a safe
concept. It's OK for short connections in the same

Hi Vyas,
I'm not familiar with this standard, but the general principle is that
2 levels of protection are required to protect operators from hazards.

Dear All,
IEC 62052-31 is standard for product safety requirements for electricity
metering equipment. It has a table 20 (given below) which details out
insulation requirements between various types of circuits.
