What must be done with the wires left in a cellular metal floor raceway after a receptacle is removed?

When a receptacle is removed from a circuit, it is essential to consider the safety and functioning of the remaining wiring. In this context, taking out the wires that were connected to the receptacle is the appropriate action. This is because leaving live wires in the raceway can pose a safety hazard, such as accidental contact or damage to the wires over time, which could lead to short circuits or electrical fires.

Removing the wires eliminates these risks and also ensures that the raceway can function properly without any interference. This process adheres to safety protocols and electrical codes that aim to protect both the integrity of the electrical system and the safety of individuals who may come into contact with the wiring.

Covering the wires with insulation or capping them off does not address the potential hazards associated with abandoned wires effectively. Leaving them in place could lead to confusion or accidental re-energization in the future. Thus, removing the wires is the best practice in this scenario.
