21、cteristics of UV laser printable electrical lightweight wires DR family for use in the on-board 115 V (phase to neutral) or 200 V (phase to phase) AC electrical systems of aircraft at operating temperatures between 65 C and 260 C. These cables are demonstrated to be arc resistant in sizes 26 to 14 (

22、115/200 V AC). In addition, cables in sizes 12 AWG and larger may be suitable for use at 230/400 V AC in pressurised zones when installed to take account of possible short circuit effects (at the discretion of the user). It shall also be possible to mark these cables by qualified compatible marking.

23、 These markings shall satisfy the requirements of EN 3838. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
