When three-conductor wiring is used, two
120 volt circuits will often share the same neutral wire. To avoid overloading the neutral, you should either move BOTH of the circuits that share the neutral or don’t move either of them.
When moving two circuits with a shared neutral, they should be connected to adjacent positions (one above the other) in the transfer switch. That will assure that the two hot wires are on separate phases and will maintain their relationship to neutral.
Select a circuit you want to back up and remove the power lead from the breaker.
Using UL Listed wire nuts, reconnect the power lead to a matching breaker in the transfer switch.
Make sure each circuit you move is protected by the same size breaker in the transfer switch. 15 Amp circuits must be connected to 15 Amp breakers and 20 Amp circuits to 20 Amp breakers.
For every circuit you move to the transfer switch, connect the white neutral wire to the neutral bar in the distribution panel.
