Called out today to investigate a GFCI controlling outside receptacles on the side of the house, gazebo, and down the hill from the house. Opening the receptacle at the side of the house, controlling the LV transformer, and the first receptacle under the kitchenette outside closest to the grill, I tested whether the GFCI would trip depending on the wires connected. The GFCI would not trip with the wires coming from the house disconnected, but would trip when connected to the wires feeding the gazebo. I bypassed the receptacle in this situation. This could potentially signify a broken or damaged wire in the ground causing the ground-fault. Another technician will come out Thursday with a circuit tracer to try and find the break. Today I replaced the receptacle and GFCI in the laundry room, and the first outside receptacles on the circuit controlling the LV lighting. Collected a partial balance, remaining balance to be collected on return. Return with circuit tracer to trouble circuit t
