Beat 3 · The shutdown demo
Make the roof safe to touch
Dale will not put a probe on anything until the system is shut down in the right order. Tap the devices in sequence. Orange means energized. Blue means verified safe.
Tap Doris on the porch first — interior loads off, nobody opens the fridge mid-test.
Open the AC disconnect. The blade swings, the inverter drops off the grid.
Hit the rapid shutdown initiator. NEC 690.12 gives it 30 seconds to bring rooftop DC conductors to 30 V or less. The countdown is compressed for television.
Then, and only then, let Dale probe the AC terminals and the DC terminals. Probing a live conductor is how you fail an inspection in front of a homeowner.
Wrong order costs Safety, and Kenneth will say something about it.
