Hello - I'm writing PE exam this month and was finding it difficult to find some good practice problems for below topics online. I'd greatly appreciate if anyone can share any online resources for these topics or attach them here on this thread. Thanks in advance.
- lightning and surge protection
- demand and energy management/calculations
- national electrical safety code
- battery characteristics and ratings
- protective devices and coordination
