Ideally yes. For me I found following the code difficult. Then compound that with needing to know the NECA <https://www.necanet.org/topics/codesandstandards/neis/the-st...> + the state codes. It's non-contiguous in the way it's written so you need to know the relevant sections and how to apply them together. Simple things add up; proper color coding of wiring, knowing how much sleeve to leave in at the edge of a box, what cable nuts are appropriate size for the number of wires bonded, size of box needed based on number of wires, how/where boxes can be mounted, space between EMT in bends, what size bus-bar is appropriate and what can share it.
