Hi
I am in the process of changing some old school light fittings to modern ones with a ceiling rose.
It’s a 60s house so uses junction boxes which is fine and I have worked out what cable goes where, I have power in, cable to switch, cable to light fitting and power out but there seems to be a fifth cable which is just connected to the neutrals, the line appears to be cut.
See the image attached, its the cable at the bottom.
I’m not going to replace the JB, merely run a switched line and neutral to the ceiling rose but I am wondering what the extra cable might be doing?
I can trace it but requires pulling up several 8x2 OSB boards in the loft which are screwed to the joists.
