Re: CQD answers published Wednesday, May 30, 2018 -Calculation Approval, Response to Comment No. 2

As an electrical inspector, I do much more than look at the physical installation. I am furnished a set of approved plans by the plans examiner. It is my job as an inspector to look at the calculations and make sure they are accurate and correct. (Mistakes do happen during the plan review process.) It is not uncommon for changes to take place during the construction phase of a project.  Often these changes will require a calculation to be revised. An inspector must be able to perform the required calculations to be able to determine if these changes will result in a code compliant and safe installation.

Hey Ed thanks for your follow up comment. You add a lot of good information about what an electrical inspector (AHJ) should do and show a great example of what all should be striving for. As previously stated not all areas have plans review requirements in place. Changes often occur, and we all make mistakes, that need to be reviewed and approved at the installation stage.
