The additional wire that is recommended for alternators that may feed 80 or more amps runs from the B terminal off the alternator (the charging voltage) directly to the battery thus bypassing the 50 amp circuit breaker. A short to ground on this new wire is not going to be protected by the circuit breaker and will indeed provide one hell of a fireworks show. However, a short to ground on other areas of the wiring circuits,
that don't back feed through this new wire, would still be protected. But, I can't think of any circuit that wouldn't back feed through this new wire so the circuit breaker effectively protects nothing.
