What must be considered when installing wall boxes on both sides of a common partition between a garage and a habitable room?

When installing wall boxes on both sides of a common partition between a garage and a habitable room, the fire-resistance rating of the partition is crucial for safety and code compliance. This rating assesses the ability of the wall to prevent the spread of fire and smoke from one side to the other, effectively protecting the habitable space from potential hazards originating in the garage.

Electrical installations near garages often require adherence to specific codes, as garages can contain flammable materials and have higher risks of fire. Ensuring that the wall boxes are installed in a manner that respects the fire-resistance rating helps maintain the integrity of the fire barrier, reducing the likelihood of fire escalation and improving overall safety for occupants.

While the electrical load capacity is important for ensuring that circuits can handle the load safely, the fire-resistance rating takes precedence regarding the separation and safety between different living environments. The distance from the ground and the length of the wires used are also factors to consider in general wiring practices, but they do not specifically address the crucial need for fire safety between a garage and a habitable room.
