Supplementary equipotential bonding in group 2 medical locations

Former Community Member over 4 years ago

Hi All,

I'm new here and a trainee electrical engineer.

I am looking for pointers on how to calculate the CSA of equipotential bonding conductors in group 2 medical locations.

Having worked on site, I know that as a standard we use 4/6mm to allow us to stay within the 0.2Ohms resistance but would like to know the theory behind it so I can include this calc in my designs to prove where the result have come from when or if ever questioned.

Thanks,

Sam

I'm looking to do this calculation for bonding conductors to ceiling grids and pipes, so where do I find the values for expected fault currents?

Would I calculate these from the highest rated circuit on the DB or using the impedance and fault current values on the DB?
