Have course we is.
My granddaughter has always been taught to speak correctly by parents (pretty much only due to them talkin' proppa). In senior school even her English teacher showed dictionary entries of both options.
 
That's not the point. However anyone pronounces it, it is spelt h.a.v.e.
The point is it is starting to appear in dictionaries spelt OF therefore it is accepted into the English language as progression or developement. Anyway let's not spoil a thread over it.
 
Or that the RCD works?

That's the multi tester I have, if I use rcd function connected to a socket on the upstairs circuit which shares the same rcd as the downstairs lights then the rcd trips correctly so I'd say the rcd does work there's something wrong on the lighting circuit causing it not to trip but I'll have to test for that another day.
 
now that's a line to earth fault so should of tripped the rcd which leaves me with more work as to why the rcd didn't trip
It's assumed that the RCD will trip at first. However, you're saying that the MCB did. It could have been that the L-E fault current was so high that the MCB operated very quickly before the RCD had a chance to operate.



Or, unluckily, you might have neutral and earth swapped at the consumer unit. When your available, try pressing the test button on the rcd and see what happens.
 
With the switch 'hanging out of the wall' as shown in your pic, is the tripping still occurring?

No the tripping stopped so I cut back the damaged cable and refitted the switch and now the circuit stays energised
