Voltage drop and circuit design..
I know that there is voltage drop in wire as a result of its length and gauge. I’ve noticed in the houses I’ve worked on and diagrams that I’ve seen lighting and small appliance wires usually go from the circuit breaker to a series of consecutive boxes.
Is there any reason to not wire off in two directions (with two separate cables) from a given box? In other words, if it results in the use of lesser total length of wire in a circuit, is there any reason you should not branch off in two directions and have more than one box in which the wires end on the same circuit?
Also, is the first box in a wiring circuit subject to less of a voltage drop than the last box because there is a shorter length of wire between the first box and the breaker box? Or does the total length of the wire in the circuit determine the voltage drop which is the same at each box?
