I was looking at my demarc tonight.
It looks like I have essentially a Blue and White wire from the street, which are crimped to the Blue and White wire of the house.
Each crimp however is a three way crimp, and the third leg go off to a test termination unit, which looks a bit like a large radial capacitor.
The test termination unit has two legs, and one leg has the blue wire attached, one has the white. This seems to be wired in parallel.
Anyone have any ideas what it is?
