Epic E1000 Technician reported finding signs of chafing on the cables in multiple areas of the aircraft that may be caused by the lack of clearance between the cables and other structures.

Narrative

During annual inspection; performing cockpit area inspection; found a large wire/cable very close to instrument panel shelf/structure" with signs of chafing. Further inspection following the cable run; found another area of chafing on the instrument panel structure/shelf. This chafing was worse than the other area. With very little clearance from structure; if any at all. I was unable to reposition or reroute the cable due to the area and the size and stiffness of the cable. A piece of Teflon was installed on the cable to stop the chafing. However; I feel this is only a temporary remedy as there is no clearance between the cable and metal structure. Owner has been advised and the manufacturer as well. The aircraft will be flown to Epic for further evaluation and final repair.I'm writing this report due to the seriousness of what I found: a 150 Amp power cable chafing on metal structure behind the instrument panel. I don't know if this is a one-off; or if there are other Epic aircraft with similar condition.The wire/cable runs from the MCR (Master Control Unit) through the firewall center of instrument panel; down below the aforementioned shelf; back up above the shelf over pilot's right rudder pedal and outboard and down and aft to aux junction box under the floor. This is a new aircraft; with only 200 hours on it."
