Even if the current was enough to trip the circuit breaker, circuit breakers normally take a minimum of 1-1/2 cycles to open. That means that the full voltage will contact the body and the resulting full current will still pass through the body, causing a potentially lethal electric shock.
Do circuit breakers protect against shock?
The normal home fuse (fuse and line circuit breaker) offers no protection against electric shock as it reacts too slowly and protects only the cables against overload and thus prevents extensive damage. Real protection against electrocution is provided only by “RCD” circuit breakers.
Will a damaged wire trip a breaker?

The most common is shutting off a breaker and not using a tester to ensure all the wires are not live. ... This results in a breaker that is turned off and another breaker continues to feed to circuit and this can result in an electrical shock if you do not test for voltage before handling the wires.
Can you electrocute yourself with a breaker?
1 Answer. Yes, absolutely . Call an electrician and make sure nobody touches the board. There might be 2 problems: operating circuit breakers must never result in getting an electric shock.
Does a circuit breaker protect you?
Circuit breakers have detection systems built into them that will monitor the level of current that flows through it. ... When the circuit breaker trips and turns off, it can shut off power to the appliance. This not only protects your home from damage, but it also protects the appliance itself .
What are three devices that prevent electrical shock or electrical fires?
The most common protective electrical items in most homes are circuit breakers and fuses . They are found in the home's main electrical panel, which provides electricity to the entire house. Circuit breakers and fuses are designed to shut off the electric current when it exceeds a predetermined level.
What to do if breaker keeps tripping?
