Who is ultimately responsible

Sep 16, 2019
Where do I find codes/docs that state who is ultimately responsible for performing the calcualtions.
Colleagues and clients have suggested that we use the client's calculations or contractor's.

I come the DuPont school...have been doing power coordination and arc flash reduction for almost 40 years now. I contend it is the "Engineer of Record" who is ultimately responsible for work....

any thoughts and white papers would be appreciated!
