I took out a light fixture in a bathroom with the intent of installing a new one before and I came across 4 sets of wires. This bathroom light (I think) is connected to an extractor fan and is on the middle floor of a three floor house and connected to a three-switch box that controls the bathroom, middle corridor and downstairs corridor lights. The original setup of the light fixture is in the photos that I have attached below. Within these the wires are:
- Green/Yellow, Brown, Blue
- Green/Yellow, Brown, Blue (with black electric tape tag)
- Green/Yellow, Brown, Blue (with brown electric tape tag)
- Green/Yellow, Black (with brown electric tape tag), Grey
How they were connected to the original bulb is pictured below.
However, lights downstairs and lights on the middle floor keeps tripping the entire house sockets and lights breaker. How can I go about effectively fixing this? Thank you
