If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

Asbestos was commonly used in cloth wiring, but not all types of cloth wiring contain it. The age, condition, and appearance of the wiring can provide clues as to whether asbestos is present or not, but the only way to know for sure if the wiring has asbestos is to have it tested.
