A human body wouldn’t conduct that much current with mains voltage. It’s just too high resistance.

Also pretty sure they mean breakers with GFCI as is required in some countries. If they just mean regular circuit breakers then yeah they are fucked.

Although tbf since it has both neutral and live in the strip it would probably short and not even reach the people. As in almost no current would go through them because ground is right next to it. This would in turn cause the breaker to trip without even a GFCI getting involved potentially.
