==Service drop==
The overhead power connection from the utility lines to the service entrance is referred to as the service drop. It has three wires; 1 [[neutral line]] and 2 [[hot line]]s. The hot lines maintain a certain potential (like 120 [[Volt|V]]) compared to the neutral line.

A mast service drop, with the weatherhead (top) connected vertically through the conduit to the electric meter (bottom).<Ref>Wikimedia Commons [Online], Available: https://upload.wikimedia.org/wikipemmons/e/ea/Residence_service_drop.JPG</ref>]]

===Mast service drop===
The mast is the combination of the conduit and weather-head that is on top of the roof (Figure 2). The service drop attaches to the mast at the mast knob. "Drip loops" serve to first provide slack that reduces any mechanical stress on the power lines and prevent any water from traveling along the lines into the service drop conduit.<ref name=A /><br />

===Clevis service drop===
The Clevis refers to the connectors which fastens the conductors of the service drop to the side of the building. In this setup the conduit and weather-head are secured to the sides of the residence below the roof line.<ref name=A />

===Service lateral===
This is an underground service entrance, the primary power lines pass through the conduit to the pad [[transformer]] input and the secondary power lines join the transformer output to the electrical service meter.<ref name=A />

==Main disconnect==
The main disconnect is utilized during emergencies to stop electrical power flow.
*The main disconnect may be accomplished through a main disconnect switch. This is an externally operated (EXO) switch, that is positioned in between the service meter and electrical panel (Figure 1).
*The main disconnect may also be accomplished by one or more circuit breakers housed in the electrical panel, in order for this to work the circuit breakers must be in series with the two hot lines of the conductors because it must cut power to all circuits.<ref name=A /><br />

==Outlets==
