Home / Is there light even when the switch port is turned off
The reason a light fixture remains energized when the switch is off is usually due to a "switched neutral" connection. In a properly wired circuit, the wall switch interrupts the flow of electricity along the hot wire, which carries the electrical potential (typically 120 volts). It's common to see your light bulb glowing even after you have turned off the switch.
I assume this is probably some kind of short or other hardware issue but wondering if anybody else has seen this. We have a C9200L-48P-4X which has a single port, which happens to be empty, in an up
