Below are a few distinctions between load and line wires.
A wire used to carry amp loads is also known as a branch circuit, and will usually be found in the distribution panel of your home. Alternatively, a single line wire provides access for new circuits with or without services requested (i.e., typical on premise wiring). Wiring that supplies power (loads) to an outlet from the service side of a breaker is called load wiring. Load wiring always reflects the high potential voltage between the hot lines at each receptacle or fixture capped by ground. Branch-circuit cable typically does not need this protection because current can’t stray toward ground; receptacles are normally downstream from breakers anyway and there’s good contact with ground through their boxes, receptacles and the earth itself.
