gfci breakers

ScoobyDoo

"We have had two flood lights and a pond pump connected to the outside outlet all summer. Now all of a sudden when we turn on both flood lights (the pond pump is off for the winter) the gfci beaker is tripped. I changed the junction box and replaced it, but it still trips when both lights are on. Don't know what to do from here.

Disconnect one light at a time and retest.
Continue this until you locate the problem.

Is the pond pump close to the house, oris a receptacle wired close to the pond.
Divide and conquer is the way to trouble shoot this.
