Discussion and questions related to the course EFI Wiring Fundamentals
Does the length of the wires affecting the size of the wire gauge used according to amperage draw? e.g if we have a 10 amps consumption and a length of 3 feet to use a 18 wire gauge and if the length is 15 feet to go a size or two bigger in diameter
yes, you need to upsize depending on length too.
heres a chart (random one off the internet, but gives you an idea)
Just to back what Shane has said, yes, the resistance of a length of copper wire will increase with length. For the length of wires we're typically dealing with for an EFI wiring harness, its not usually a concern, but it is worth being aware of.
