According to NEC 314.29(A), electrical boxes are required to be accessible. Since the pull box is currently above a grid ceiling that is being converted to a gypsum ceiling, it will no longer be accessible. There are two options to address this issue:1. Relocate the box to another accessible spot

This involves moving the pull box to a new location that is easily accessible, such as a junction box mounted on a wall or a ceiling-mounted access panel. This option provides permanent and convenient access to the box.2.

Provide an access panel in the gypsum ceiling

This involves cutting an access panel into the gypsum ceiling and installing a hinged or removable cover. The access panel should be sized appropriately to provide access to the pull box and any other electrical components that may be located within the ceiling cavity. This option allows access to the box without having to remove or replace the entire ceiling.The best option depends on the specific circumstances and requirements of the installation. Factors to consider include:

Accessibility

The relocated box or access panel should be easily accessible for maintenance and troubleshooting purposes.

Cost

The cost of relocating the box should be weighed against the cost of installing an access panel.

Aesthetics

Relocating the box may disrupt the aesthetics of the room, while an access panel can be placed in a less conspicuous location.

Future maintenance: Consider the likelihood of future maintenance or upgrades that may require access to the pull box.In most cases, providing an access panel in the gypsum ceiling is a more practical and cost-effective solution. However, if the box is located in an inconvenient or inaccessible location, or if frequent access is anticipated, relocating the box may be the best option. Flag for review
