How to Read the Circuits
Below is a simple guide to what symbols mean on the circuit diagrams. For some of the symbols there are descriptions as to how they function.
Wires
Wire numbers have been deleted from the original engineering circuits. This allows the type size to be increased for improved legibility of the service circuits.
Wires vary in size to allow different current to be carried. For example a wire with a diameter of 0.50mm (This is the diameter of all the internal copper strands together) will carry 11A (dependant on ambient temperature) whilst a wire with a diameter of 2.00mm will carry 25A.
