when installing the electrical wires from the circuit breaker box of a generator to the home's main circuit beaker box, what does this mean: "balance must be maintained when moving circuit locations from main electrical distribution panel to emergency load center. circuit breaker positions alternate buss bars vertically. circuits sharing a neutral wire should either be moved together to adjacent positions in emergency load center or not moved." thanks.

The electrical supply is 120/240, ie you hve 2 120 volt (with respect to neutral) leads (legs) and thus bus bars.

You need to keep the 120 volt loads balacned on the 2 legs (bus bars).

The second comment is for 240 volt loads and multiwire circuits.

In most cases 240 volt loads won't be on the standby power (AC, dryer, stove). But there are a few such as well pumps or sewer pumps that might wired for 240 and you want them on the standby power. The 2 hots need to be on different legs to get 240 v.

Also sometimes multi-wire circuits are used, where 2 hots share a neutral. Sometimes used on kitchen circuits, but they can be used other places. Again the two hots need to be on different legs or you will over load the neutral for that circuit.

If you still don't understand this it is time to get an electrican.
