Everything you need to know about aircraft wiring, electrical loads, losses in the wiring, wire size, breaker size, fuse size, etc is all contained in AC 43.13-1B, Chapter 11. This is a book that is available for free download as a pdf, or can be purchased in print from most any book vendor, both new and used. This book is referred to as the Aviation Maintenance Technician's Bible and should be in every shop.
There are little tidbits in there that are important: For instance, one might need to use a different gauge wire if it is in a wire bundle than you would use in free air. Length of the wire run may affect the recommended wire size. Wiring should always be rated for more load than the fuse or breaker it is on. The breaker is not there to protect the electrical devices. It is there to trip at a lower rated amperage than the wire in order to keep the wire from potentially burning or causing a fire. And, of course, we are all using wire with Tefzel insulation as it resists melting and is not toxic if it burns. It's all there in AC 43.13, along with a lot of other really good stuff that will answer questions about almost anything related to Aircraft Acceptable Methods, Techniques, and Practices. -Jeff Scott Arkansas Ozarks -- KRnet mailing list KRnet@list.krnet.org https://list.krnet.org/mailman/listinfo/krnet
