Quick installing, electric chime and back box

Abstract

An electrical back box of galvanized metal or plastic with a barrier mounted in its interior. This barrier is the support for a low voltage transformer and the means of separating the low and high voltage wiring chambers. Knockouts provide access into these tow chambers for the required electrical wires. Retainer slots located in the interior of the box at the mounting end and at the opposite end provide and insertion point for wire springs. These wire springs are attached to a chime or any type of equipment that may utilize this backbox. When thrust into the retention slots, these springs provide a pulling force that snug the equipment up to the opening of the box. When this back box and transformer are used only for a source of low voltage power then there are two different types of covers that will cover the opening either flush or surface mounted and these make it electrically safe. These covers are mounted by the same wire springs method and are of plastic. When a metal cover is required then it will be supplied with a means of bonding to the equipment ground in the box thus providing electrical fault protection. When different size transformers are needed they can be mounted to the removable barrier but will require the mounting hole in the barrier to be individually sized.
