Whenever I see a #14 clamped to a cold water pipe I always try to understand how this can ever be seen as an approved wiring method.
There is
no proper strain relief
no protection against damage
no proper fitting to the box
no approved staple
Then I remember that using the cold water at the nearest point on the GEC was limited somewhere to the first 5 feet on entrance to the building.
So between these two images, I cannot see how this is always treated as a normal installation.
Old timey yes, but how can you do that with new wire and a shiny clamp?
When you pick up K&T you carefully land it in a box and then go on with the normal procedures for, say - Romex.
When you have a #4 GEC to the cold water, you go to the first 5 feet in the entrance, and then you land the wire on an approved clamp on both sides.
The #4 solid does not need to be protected against damage
#6 or stranded #4 needs better treatment like pvc or emt or ac cable
How does this #14 seem so normal installation in 2013.
Back in the '70s I agree but not now...:dunce:
