    Sizing and installing device boxes. Sizing outlet boxes is the maximum number of conductors permitted in a standard outlet box, is generally limited due to safety. Therefore choosing the correct size outlet box is the first step in correctly installing a receptacle. The main factor to consider is buying an electrical box is volume, or cubic of space inside the box. Installing boxes: The NEC (National Electrical Code) lays down the following requirements for installing boxes: 1. The box selected for the given application. For example, a box listed for use in wet location must be listed for use in that location. 2. The box must have sufficient volume and must allow free space for conductors. 3. Conductors entering the boxes as well as fittings must be protected from abrasion. 4. Boxes must be installed and supported properly, and the finished installation must be accessible for later repair or maintenance.
