[QUOTE="DaveS79, post: 445267, member: 28820"] Excuse me if this been answered million times but doing some testing at min and been advised by supervisor to join L and N and test these to earth for some lighting circuits and other circuits that have appliances connected. I know there is some logic in this but I don't fully see it. Even if these are joined am I right to still think that any live to neutral short will not be picked up. I thought point on joining these was to detect neutral shorts but when I join these and test to earth and create a short delibrately to see if it is picked up it isn't. So then what is the point of this test anyway? Thanks [/QUOTE]
