School has 100A, 30 pole, 120/208V panel without spare breakers. I would like to replace existing panel with new 42 pole in order to energize new loads.
1. Can I just connect existing loads "as is" to new breakers without checking compliance of existing wiring and loads with current NEC (GFCI, AFCI, and other stuff in code)?
2. What section in code should I read/check.
