There are three types of wires to use for electrical purposes: The wire size for 125 amp service may differ depending on the material. Why do the wire size for 125 amp service differ depending on the wire types? You might have noticed the difference in size due to the wire material, i.e., copper and aluminum or copper-clad aluminum.Ī question may arise in your mind: why this difference? The current takes an alternate path and flows through the ground wire instead of your body during short circuits. In situations like electrical accidents and short circuits, the ground wire saves us from shocks. The ground wire doesn’t have to be the same as neutral or live. The wire size of the neutral and live wires must be of the same size since both of them carry currents. The neutral wire carries from the hot wire and transfers it back to the main power source. The hot wire carries the current from the main power source to different outlets. Wire size (aluminum or copper-clad aluminum) The kind of wire also determines the wire size required for 125 amp service. Otherwise, if you use a smaller wire, the voltage will increase, and the wire won’t be able to hold the current load.Īs a result, the wire will heat up and cause a fire hazard.Īlso read: What Kind Of Wire Goes From Meter To Breaker Box?
