Per 600.7(A)(2), what is the minimum size equipment bonding jumper required to be connected from a grounding terminal on a switch for a neon tubing outline lighting circuit protected at 30 amperes?

Explanation:
Bonding jumpers must be sized to provide a reliable fault path, based on the circuit’s overcurrent device rating. For equipment bonding in neon-tube outline lighting, the size is dictated by NEC 250.122. When the circuit is protected at 30 A, the minimum copper equipment grounding conductor size is 10 AWG. A smaller conductor (12 or 14 AWG) would not meet the requirement for a 30 A circuit, while a larger one (8 AWG) would be acceptable but isn’t the minimum. So, the smallest size that satisfies the rule is 10 AWG copper.
