True or False: Disconnect switches or breaker isolation switches are designed to handle fault currents?

Disconnect switches or breaker isolation switches are primarily designed to safely disconnect a circuit from its power source for maintenance or inspection. Their main role is to ensure that there is no voltage present while work is being performed on equipment. However, these switches are not intended to handle fault currents, which are usually much higher than normal operating currents that can occur during a short circuit or other fault conditions.

fault currents may require specialized equipment, such as circuit breakers, which have specific characteristics to interrupt and manage these higher currents safely. Disconnect switches generally lack this capability and are not built to protect against fault conditions. Thus, stating that these switches are designed to handle fault currents is inaccurate.
