what is the purpose of bus-bar in C-152 ?
Copper ice maker water lines are always far superior to any plactic ones. Once installed, they will last forever, they won't leak, they won't burst on you. plactic ice maker kits are available because they are cheap. You can get ice maker kits that has copper tubing with brass fittings. The cheepie stores won't have them, though. go to like a good hardware store, Lows, or Home Depot. Those will cost more. Good luck
All the demos refer to copper because that is what those cheap clamps are designed for. Don't use it on PVC. It will not seal.
do the stainless flex it is worry free and not that expensive
I have noticed you are asking a lot of questions about the CE-152 in general. I would recommend you either download a copy of AC 43.13-1B from the FAA web site or purchase a copy. The AC will answer all the general system questions you have. I would also recommend you purchase a copy of FAA-H8083-25 Pilot’s Handbook of Aeronautical Knowledge. I would also recommend you learn the make and model of the aircraft you are flying such as all Cessna's start with CE the model you are refering to is a CE-152 this should also be on the airworthiness certificate in the aircraft.
A busbar in any situation usually refers to an electrical power distribution system. It refers to thick strips of copper or aluminium that conduct electricity within a panel, switch plate, circuit breaker box, etc. In a C-152 or any other aircraft they are used along the circuit breakers and power switches to supply electrical power to all the switches or breakers. Its just easier and more efficient to use a fixed shape BAR than heavy wiring to interconnect the devices.
