A pattress box is used in electrical applications to contain and protect components inside walls. It can be made of plastic or metal and is often mounted with wall anchor plates. Known by various names, its function remains the same.
Also known as a pattress box, a pattress is a type of container that is used with electrical applications. Commonly used with the installation of light switches and sockets, this type of box provides for the containment of the portion of electrical equipment located inside the wall, protecting the components from possible damage over time. In some cases, the box is surface mounted to the wall, serving to protect the wiring and components from exposure to dust and other potential contaminants.
The pattress box is a simple device that looks a lot like any type of box. Featuring a bottom and four sides, the container fits neatly into what is known as a serving dish. When installed correctly, the box is more or less sealed, providing a reasonable level of protection to the contents. At the same time, the presence of the box and the plates prevents accidental contact with the electrical cables, a particularly important factor when the box is positioned on a masonry surface rather than being recessed into a wall. There is usually an opening along one of the sides or top of the enclosure to allow electrical wire to pass from the box and along a wall or beam to a power source.
In terms of construction, a pattress can be made of a strong plastic or some type of metal. In housing situations that normally require the placement of the box inside the wall, the use of plastic containers is not uncommon. Metal enclosures are often used in commercial or manufacturing environments where it is considered a good idea to have access to electrical wiring without the need to pull it out of the inside area of a wall. In both applications, wall anchor plates are often used to mount the box in the correct position and hold it in place more or less permanently.
Mistress is known by a number of other names, with local customs often dictating which name is used. In some parts of the world, the container may be known as a wall box when pushed into the wall. When the wall is composed of drywall or some type of wood construction rather than brick or concrete blocks, it may be referred to as a drywall box. While the name may change, the essential function of the mistress remains the same.
