To stop rain water from entering the service stack.
On an overhead service, during periods of rain, water will run along the overhead service wires. Water would run in to the service riser and in to the top of the meter, the drip loop allows the water to drip off of the conductors instead of running in to the meter.
Drip loops prevent water from following the electrical service conductor into the service panel, causing shorts and other dangerous situations. So long as the low point in the cable is below the main lugs, water will collect and drip from there, and not continue to the exposed live parts of the panel. We usually have a drip loop in a place right next to the place the conductor penetrates into the head or the place where it "goes through" a wall or barrier. That way there is only a short "uphill" run between the drip loop and the penetration point for the conductor.
It allows for water to cascade off the lowest point of the wiring BEFORE it enters the head of the service pipe...for the same reason wiring CANNOT be routed below fluid lines in aircraft. 5 years FAA Airframe & Powerplant mechanic
to prevent loose ends
then your program will never ends, too unless you pressing the ctrl+c or kill it through your os. can i know the purpose of you creating the loop that never ends? is it just a mistake or are you doing it on purpose?

This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask for the answer. Earn your diploma.

The utility company is not governed by the electrical code and wire sizing. They use the reasoning that they are on call 24 hours a day 7 days a week. If there is a problem of a wire burning off due to overloading from under size wire, they will come and replace it, no charge to the customer. A contractor can not give this guarantee. He is governed by the electrical code for wire sizes and by the electrical inspector for approval of his installations.
One can purchase a robin loop tester from Ebay. One can also purchase a robin loop tester from electrical shops or from electrical dealers which carry robin loop testers.
There is no such thing as an "electrical citric".

to terminate a loop.
This is an excellent question and yes it could.There is a "drip wire", there is a "drip loop".The drip wire is in the triplex that runs from the utility pole providing power to your house and the service mast on your house. The lineman will leave a sag in the wire so that water that accumulates on the wire will run along it to the lowest point and fall off harmlessly.The drip loop is the loop on the wire that runs into your house from your service mast. When these wires are connected to the triplex from the utility they should be tipped down so that no water will run down them. Now, this is the interesting part, at least to me...Even if you do all that, you can still get water in your breaker box. If those connections are tipped up, water can run down inside the insulation of service wire between the copper or aluminum and the inner jacket of the insulation. You wouldn't think it could, but it sure can. The only way I know to fix that is to have the utility company come out and if there isn't a loop, have them make one. They make think you're nuts, but that's ok, insist. So, what if you live in a cold climate or have an underground service. You can still get moisture in the panel. At the back of the metre base the electrician should have put in some "duct seal" . This prevents condensation from occurring from either the cold outside and the warmer inside, or warm outside and the airconditioned inside. Good luck, Andy
