Replaced gfci in the backyard beside pool equipment coming out of control panel that was controlling pool lights due to it tripping. Found that the gfci was not sealed properly and tripping before 60ms but also found a couple of bad pool lights out of 7 or 8. Explained I can troubleshoot and go through circuit and find why it is tripping but also explained that it is most likely a bad light and that there are multiple boxes to go through and troubleshoot. Customer wants to get her pool lady out to see if she can just replace the lights and then see if it keeps happening. Explained the gfci is tripping for a reason and is doing its job and if we come back we will automatically go straight to troubleshooting. Explained to customer we do not work on control panel for sump pump.
