It is a ring circuit, then?
If you have an appliance plugged in and switched on, at another socket or an FCU, then it will be providing a path between the P and N. Unplug them all and try agan. Do you know the resistance between the red and black?
p.s. in answer to your question "no"

If it is something simple like a lamp, a kettle, or a heater, then, yes. They work by connecting a piece of (resistance) wire between the P&N. It gets hot by the current passing through it (you knew that, didn't you? Or are you the guy with a cannabis plantation in his loft?).
You will have someone along in a minute saying you should check the resistance in the ring, and betwen P&N, and to earth.
But if you are searching, e.g. for a cut or disconnected point in a ring, a continuity test is a start.

test between black and black, red and red, earth and earth. if all three give continuity, you have a ring. ideally, you should be measuring resistance too, as you can have continuity but high resistance (as your red-black continuity is probably showing)
As said, unplug everything, turn off all switches, FCUs, and try again.

Why did you measure between red & black?sotonblue said:
