According to the size chart recommendations from the 2002 edition of the NEC, the minimum wire for 50 amps should be 6 AWG for copper. For aluminum, it should at least be 4 AWG. However, these answers assume that there's no voltage drop to consider. The NEC considers a 5% voltage drop as the maximum ...This article will discuss what size wire should be used for a 100 amp sub panel that is 300 feet away from the main panel and why it is important to select the right size. The National Electric Code recommends that to wire a 100 amp sub panel 300 feet away from the main panel, you should use 2/0-gauge aluminum wire or 4/0-gauge copper wire. The ...How a Subpanel Is Connected. When an electrician installs a subpanel, the usual process is to first run a feeder cable from the main panel to the subpanel. This is typically a three-wire cable with three insulated conductors plus a bare copper ground wire. The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp ...Ensuring the appropriate wire size is selected is essential for maintaining safety and preventing potential hazards. According to the National Electrical Code (NEC), it is recommended to utilize 8-gauge aluminum wire when installing a 100-amp electrical service. This is because 8-gauge aluminum wire can handle up to 50% more current than 10 ....
