Is the electric garage door opener popping the flood lights?
Ok here it is one 15amp circuit going to the garage
On this circuit is a GFI outlet, a light inside, two flood lights outside and the garage door opener. It was this way when the house was purchased a few years ago.
There was no problem up till now, the two outside flood lights fail in a few weeks.
They are GE Par flood lights, I replace the two sockets. The voltage is 120v, I donít have an amp meter.
Here is where the issue may come in as I was putting my tools in my box. The child says I notice when I opened the garage door the flood lights popped. So I remove the flood light bulb and screwed two standard 40 watt bulb and cycled the garage door a few time checking the volatage and it was 119v to 120v. The 40 watt bulbs did not pop. Again I donít have an amp meter.
So is the garage door pulling too many amps popping the bulbs?
The garage door opener is not to blame unless,
1. It starts with a jolt that causes excessive vibration to the floodlight fixture,
2. You really have a three wire circuit (multiwire branch circuit) to the garage that amng other things gives a choice of 120 volts or 240 volts and there is a defect (loose neutral connection) that causes the voltage for the lights to go above 120 volts when the garage door opener is activated. You will see abnormal brightening of the lights if this happens.
2. No, It is two wire (UF black, white, bare ground) 120 with a ground wire. I checked voltage 120v no 240v. The circuit is on a single 120v 15amp breaker.
I would be checking all the neutral connecttions,
One of them might be loose/dirty.
The most likely thing that makes lamps go pop is overvoltage.
The second is mechanical damage (a crack in the glass).
