How To Install Electrical Service Entrance

The cabinets can be in different locations, in which case the service entrance conductors are those that run between the meter chiffonier and the service equipment cabinet(southward). The cabinets can also be side by side to each other, as they oftentimes are in The Word'southward territory. In this configuration, the service entrance conductors are either metallic double-decker bars or short lengths of wire between the meter cabinet and the service equipment.
