Which type of conduit body allows access to wires for maintenance?

The option indicating that both Type T and Type L conduit bodies allow access to wires for maintenance is accurate because each provides openings that facilitate wire pulling and maintenance tasks.

Type T conduit bodies are specifically designed to connect three sections of conduit. They feature a terminal that allows for easy access to the wires within, making it simpler for electricians to maintain or reroute the wiring as needed without having to remove the entire conduit run.

Type L conduit bodies, on the other hand, are utilized for making turns in conduit systems while allowing for access to conductors. This feature is crucial when inspecting or replacing wires, as it does not require dismantling large sections of the conduit system.

The combination of these two types underscores their functionality in providing maintenance access, making the choice of both Type T and Type L as the correct option logical. This ensures that electricians can perform necessary upkeep efficiently and safely, which is a vital aspect of electrical maintenance practices.
