Electrical metallic tubing is permitted to provide physical protection for service entrance conductors. True or False?

Electrical metallic tubing (EMT) is indeed permitted to provide physical protection for service entrance conductors. This means that EMT can be used to enclose and protect conductors that bring electrical power from the utility supply to the service equipment in a building. EMT is commonly employed because it is a lightweight, non-threaded tubing that is resistant to physical damage and corrosion, making it an effective choice for protecting conductors.

In many electrical codes, the use of EMT is specified as a suitable method for protecting service entrance conductors, under certain conditions. This protection helps ensure safety by shielding the conductors from impact and environmental factors, which could otherwise lead to electrical hazards or damage to the conductors themselves.

While the other choices might suggest conditions or limitations that could apply in specific contexts, they do not align with the general acceptance of EMT as a protective measure for service entrance conductors. Therefore, the conclusion that EMT is permissible in this application is accurate and supported by standard practices in electrical installations.
