WHY CABLE SIZE IS IMPORTANT
Avoid wasting hard-earned energy through inefficient cable sizes.
KEEP VOLTAGE DROPS DOWN
Temperature, wire length and current can all lead to voltage drops if the cables aren't sized correctly.
SIZE ALL COMPONENTS FOR THE CABLE & CURRENT
Size fuses to protect the power supply and wire. They come in different styles too: blades, midi's & ANLs. It's not at all confusing!
Keep switch sizes to a standard 20 amps by installing correctly sized relays on higher current appliances.
KEEP WIRE SIZES STANDARD
Use this online calculator to determine every cable size you need, and use the optimum sizes so you don't end up with dozen of different wire sizes.
