DC Side Surge Protection NEC requirements
Originally we designed a projects with an engineer during an RFP stage as follows:
The final outcome was redesigned from a different engineering group came out as:
The project had been signed off by (2) customer engineers, and inspectors and was doing fine until we had lightning damage.
We are trying to mitigate the damage.
Question is does the NEC require SPD on the DC side?
Does the ground rod per array meet some level of lightning protection?
Would "errors and omissions insurance" cover this for the engineer that made the change? :?
