Does Current Flow on the Neutral?

There are a lot of people out there discussing this whole neutral thing and it can be a little difficult to understand what is going on without being able to see what is happening.

Let’s start this off by stating yes, current does flow in a neutral. But there are times when it doesn't. To understand this we need to look at exactly where in the circuit we’re examining. If we are near a device, somewhere in a branch circuit, there will most likely be current flowing at that point. If we look further forward in the circuit, to the electrical panel, this is where things get interesting.

If a panel is perfectly balanced, and we have 2 loads that we are looking at, then each of those branch circuits will have neutral current flowing throughout the entire branch(es). But the neutral from the electrical panel back up to the transformer, will not. When two loads are turned on, and are exactly the same, the neutral current can actually balance out and, in fact, cancel each other out.

Neutral conductors from a panel back to a source will carry any imbalanced current that exists between any two phases on the system.
