I have been helping my dad in the garage and we have an armoured cable with 4 wires.
Red - Live
Yellow - live via a switch
Black - neutral
Blue - is just taped at the end these were connected to an old garage consumer unit. There does not seem to be a earth wire?
Testing with a light :
Red and black - light on
Yellow and black - light on via switch
Blue and and black - no light
Red/Yellow with blue trips the fuse.
is it right that this would imply that there is no earth?
thanks for any help.
