SkyView System Installation Guide - Revision AA 2-5
Table 4 contains power specifications for SkyView units that are powered from aircraft power (not
powered by SkyView Network). The circuit protection recommendations are suitable for most
installations and assume that you are using Dynon Avionics harnesses and/or are following the
wiring advice in this Installation Guide. It may be possible to use different sized circuit protection if
the protective device has suitable load overhead for the device(s) connected to it. It is important
that circuit protection devices be appropriately sized to protect the wiring connected to them. 5A
circuit protection is recommend in most cases because that is the smallest circuit breaker that is
commonly available in certified versions, and Dynon Avionics wiring harnesses specify wire of at
least 22 AWG.
