Final answer:
Grounded equipment can still cause electrical shock, which is why the statement is false. Grounding reduces but does not eliminate the risk of shock, especially with high short circuit currents or due to electromagnetic induction.
Step-by-step explanation:
The statement that grounded equipment cannot cause electrical shock is false. Grounding is a safety measure designed to reduce the risk of electric shock by providing a path for electric current to go directly to the ground in case of a fault. However, grounding does not guarantee complete protection against electric shock.
In situations where there is a large short circuit current, a voltage can still be produced on the case of a grounded appliance. This occurs because the earth/ground wire has some resistance, which isn't zero. Also, electromagnetic induction can cause an electromotive force (emf) on the case of electrical appliances. If the case is not properly grounded, the induced voltage might result in a leakage current that could cause a shock, as highlighted in the referenced Figure 23.35.
