Hello and welcome to Just Answer. My name is ***** ***** I will be happy to assist you with your electrical question.

1) The breaker is tripping due to incorrect wiring.

2) Are the exterior lights controlled by a wall switch or a photo eye or a built-in dusk-to-dawn dimmer on the lights?

Customer: replied 10 months ago.
The exterior lights is wierd to a switch with both lives going into L1 and both neutrals are in L2
Expert:  Kevin replied 10 months ago.

Thanks for the replies.

1) If the switch is a single pole type, it should contain 1 hot from the circuit feed and then a switched loop wire that extends from the switch out to the lights. the neutral is not wired to the wall switch. Only the hot circuit feed and the switched loop are connected to the switch.

2) Is this how the switch is wired?

Customer: replied 10 months ago.
the neutral should be connected via connector block and not in switch
Expert:  Kevin replied 10 months ago.

1) The neutral wire from the circuit splices directly to the light fixture neutral wire and bypasses the wall switch.

2) Neutrals are never allowed to be switched. Only hot wires are switched.
