Wiring A Sub Panel. Web 1 1 1 a 40 amp breaker needs a minimum of 8 gauge, larger gauge won't hurt. Wiring from a sub panel will consist of a black wire (power), white wire (neutral), and copper wire (ground).
Strip enough wire sheathing to attach the wire; A typical amperage and voltage for a subpanel might be 30 amp, 240 volts. I'm adding a 100amp (homeline) main lug load center in my attached garage.
I'm adding a 100amp (homeline) main lug load center in my attached garage. Then remove a knockout slug and clamp the cable in place. My 200 amp service entrance is full.
Strip enough wire sheathing to attach the wire; Web the biggest difference between a subpanel and a main panel is that the ground and neutral buses on a subpanel have to be separated. Here are some examples of where putting a subpanel might make sense:
Web subpanels are usually used to extend the wiring for multiple branch circuits to a specific area of a home or to a building at some distance away from the main panel. If sub panel is in the same building then i think you only need the ground wire back to main. You see the complete process, from start to finish.
Web the basic structure of an electrical subpanel is the same as a service panel, with the main feeder wire leading into bus bars and circuit breakers. Pretty straight forward with a couple of tips to ensure you. The grounding bus is always bonded to the enclosure no matter what.
Items used in this video: Keep in mind that there is no need to bond ground with neutral in the subpanel (as they are already bonded in the main panel). Web wiring the sub panel.
