⚡ OPENING HOOK

Power doesn't just need to be delivered...

It needs a safe way to be stopped. ⚠️

🧠 CORE IDEA

⚡ NEC 625.43–625.46 covers safety requirements for electric vehicle charging systems.

EV equipment must be designed and installed so qualified persons can safely:

⚡ Disconnect power

⚡ Service equipment
⚡ Prevent unexpected energization

Safety isn't just about supplying power...

It's about controlling it.

⚡ CODE CONNECTION
