Hi I’m new to this and was wondering what size wire is to be used for all the different components? From battery to relay, from relay to pressure switch, to compressor, to solenoid … And anything else I may have missed.
Thanks
Welcome to the forum.
The wiring size is based on the round trip length and the amount of current passing through the wire.
This table shows the wire size versus the round trip length versus current. Use the 3% drop table.
Ensure that appropriate connectors and crimp tools are used for the wiring. They need to have the correct barrel size for the wire and the correct hole size for the stud diameter.
