what capacity circuit breaker should be installed with Sky view system. I install two 5A circuit breakers for two separate displays. Is it fine ?
Please advice
That should be fine. The circuit breaker is needed primarily to safeguard the wiring.
The following is our recommendation from the SkyView Installation guide:
Power Input
SkyView displays have a primary power input that is compatible with 12 volt and 24 volt systems (10 to 30 volts DC). There are two unterminated solid red primary power input wires (to reduce current loading in each wire—these are not for redundancy and both should be connected to the same power source) and two unterminated solid black primary ground wires.
Ensure that there is an appropriately rated breaker or replaceable fuse on the primary power input. A 5 amp breaker or replaceable fuse is sufficient for the majority of installations. Reference the Specifications Section of the System Planning Chapter for more information.
