Final answer:
The statement that a safety rule which should never be violated is the tagging and locking of the electrical disconnect before working on the equipment is True. This crucial safety procedure is known as Lockout/Tagout (LOTO).
Step-by-step explanation:
The statement is True, and the practice of tagging and locking out the electrical disconnect is a critical safety step known as Lockout/Tagout (LOTO) to prevent accidents and injuries. is essential for preventing accidental or unexpected energization, startup of machinery and equipment, or release of stored energy, which could result in harm to personnel. The implementation of LOTO is supported by the use of various electrical safety systems and devices, such as circuit breakers, fuses, and the three-wire system, which include live/hot, neutral, and ground wires to prevent both thermal and shock hazards.
