The size of the ground wire for a 100 amp service is determined by the National Electrical Code (NEC). The NEC specifies that the ground wire must be at least 1/0 AWG copper or 2/0 AWG aluminum. The ground wire must also be connected to the main electrical panel and to all metal parts of the electrical system.
Oct 2, 2023 · The Correct Wire Sizes for a 50A Sub Panel. 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 ... About 200-Amp Service Wire Size. The National Electrical Code mandates a maximum #2/0 AWG or #4/0 AWG copper wire coiled within a standard 1.5-inch PVC 40 or 80 conduits for underground service. When installing three inputs in the same conduit, we suggest 2 or 2.5 inches. You should use copper or aluminum-coated wires that measure at least AWG ...A 100-amp panel can handle a feeder rated anything at 100 amps or below. The actual rating of the feeder is based on the size of the breaker to which it is connected in the main panel, which in turn determines the size of the wire you need. The size of the required EGC is based on a table in article 250 of the code.Required Wire Size: #0AWG (1/0 AWG) Cupper (#3/0 for Aluminum) based on the above calculation and AWG chart and tables based on NEC, the right size wire for 100 amp circuit at a distance of 100 feet from the main panel to subpanel is 1/0 AWG (AKA #0 AWG). It means, an the wire having ampacity of 150A is sufficient to deliver 100A to the the ...For a 50-amp sub-panel, use #8 THHN wire; for a 100-amp sub-panel, use #2 THHN wire. Connect the main panel to the sub-panel box with the cable. Run black, red, white, and green wires from the sub-panel box to the main panel box. Keep the copper wire inside if the temperature is cold outdoors to keep it warm.
In this case, instead of using a 2/0 copper wire, you should use 300 kcmil copper with only a 2.78% voltage drop. This suggested size wire for a 200 amp panel will work for both single-phase and three-phase installations. On the other hand, if you are tight on budget, you can use 500 kcmil aluminum.
If you consult the KCMIL list above, you can see that the 350 KCMIL wire is perfect for 200 amp service 100 feet away. That’s because it has a 310A ampacity. You can make a similar calculation for 50 feet (10% addition), 150 feet (30% addition), and 200 feet (40% addition), and choose the corresponding KCMIL wire.
