Any kind of structure or electrical installation needs to have an electric service unless it has an onsite power supply or attaches using a feeder to some other installation that itself has a service.
Requirements, as well as interpretations, stay in National Electric Code solutions. It specifies an electrical service as part of the setup from the energy factor of connection to the first overcurrent device, normally the main breaker. Fuses are permitted yet have been largely supplanted by the breaker.

The factor of the link is defined by the utility. For an airborne solution, it is generally a couple of inches upstream from the Weatherhead at a crimp link. The Weatherhead is a waterproof cap on the end of the avenue that allows the incoming cords to go into without letting in water. It’s formed like a hood and the wires enter it dealing with down at an angle of a minimum of 45° to assist to keep out the rainfall. A rubberized gasket seals against the wires. Overhead cords going into the Weatherhead are given a drip loophole allowing water that gathers drip off before reaching the Weatherhead.

The electrical contractor, such as Berkeys Plumbing, Air Conditioning & Electrical, in support of the proprietor, affixes Type SE wire to the building, bringing it up high enough to ensure that the airborne conductors have the called for ground clearance. If this is not feasible, a masthead solution should be developed, raising the factor of connection higher than the building.

The specific conductors are separated and transmitted via openings in the Weatherhead, leaving enough free cable for the energy to crimp onto, as well as developing the drip loophole. Some energies do all this work, the consumer supplying the products. An option is to put this segment in the avenue, either PVC/metal. Various other wiring methods are permitted. 

The electrical expert around Whoazone at Grapevine Southlake mounts the meter unit, generally outside wall surface at an area accepted by the utility. The height ought to be 5 feet to the center of the meter to ensure that it can conveniently be read.
