U.K. Pics: Service drops - 07/12/02 10:20 PM
Here is a typical older-style overhead service with two lines:
It's not clear from the photo, but in this case the upper line is the neutral and is bare.
Newer overhead drops use a single cable with concentric neutral (and outer PVC sheath). This one has clearly been converted from an older-style drop (note the spare porcelain insulator):
And here's an wider view:
This particular pole has only 2 of the 3 phases run to it (entering top left) and feeds four houses -- Two newer concentric cables going to the right, one older twin-cable drop to the left, plus one underground service. The thin line farther down the pole is telephone.
