Jim,
This choke is on the *Lamp *side of the ballast, not on the *Line *side,
so it is unclear what a short circuit among any of the wires on the Lamp
side will do. It largely depends on the ballast circuitry.

I respectfully disagree. The choke in the green wire and the common
mode choke both are 300uH. A short circuit current between the hot
and the green wire would pass through both chokes in series. At 60 Hz
the total impedance is 0.2 ohms which is not going to affect the
breaker or fuse blowing.
But it's NOT 60 Hz, it's an impulse. And if the choke is effective at
killing RFI, it's got significant resistive impedance at the
frequencies of that impulse.
The question is not WILL it blow the fuse/breaker, but will it blow
FAST ENOUGH to protect someone from electrical shock.
