Wiring Guide
Selecting the correct size and type of wire will enhance the performance and reliability of your
system. The size of the wire must be large enough to carry the maximum current expected
without undue voltage losses. All wire has a certain amount of resistance to the flow of current.
This resistance causes a drop in the voltage from the source to the load. Voltage drops cause
inefficiencies. The wire sizing guide below provides the minimum wire size needed to limit
voltage drops to 10% at a given distance in a 5vDC system.
