In which phase are devices and fixtures typically installed?

The trim out phase is the stage in electrical installation where devices, fixtures, and covers are installed. This phase occurs after the rough-in phase, where the framing of the building is complete, electrical wiring has been run, and the rough connections are made. During the trim out, electricians will install items such as outlets, switches, light fixtures, and faceplates.

This phase is crucial because it gives the final appearance to the electrical system and ensures that all devices are correctly connected and functional. It’s also when any adjustments can be made to ensure that everything is placed correctly according to the homeowner's or designer's specifications. Additional components like circuit breakers may also be installed during this time, finalizing the setup for subsequent testing.

In contrast, other phases like rough-in involve the initial wiring and installation of the backbone of the electrical system, hook-up typically refers to connecting appliances and ensuring they are wired correctly, while testing is the phase where systems are powered on to verify everything works as planned.
