400 amp ground wire size
Section 250.122 (A) General. The rules for sizing wire-type equipment grounding conductors – copper, aluminum, or copper-clad aluminum – are: Use Table 250.122 to establish the minimum size – based on the ampere rating or setting of the automatic overcurrent device protecting the circuit ahead of the raceway or equipment.To use the calculator, enter the Maximum Current in Amps of the circuit, and the Length of the Wire, and operating Voltage. Typically most automotive systems run at 13.8V, but you can select 6, 12, 13.8 (Default) or 24 volts. If the wire gauge is OK to use it will have a 'Check Mark' on the same line.

For a 100 AMP service, the recommended wire sizes are 4 AWG or 2 AWG for copper wiring and 2 AWG, 1 AWG, or 1/0 AWG for aluminum or copper-clad wiring. If the distance is more than 50 feet, it’s advisable to use #2 AWG copper wire. For underground service, you can install the wire inside a 1.25-inch PVC conduit, either Sch 40 or Sch 80.You are corresponding with Joseph - Your personal On-Line "Electrical Consultant". *****Click here to view my profile*****.

The cost to upgrade to just a 400 amp panel will set you back between $2000 to $4000. Things to consider in the cost of your upgrade include: Replacing your current panel box with a larger one. Hiring a licensed electrician. An average upgrade will take about 8 to 10 hours of work. Most professionals will charge between $50 and $80 per hour ...Here are some common mistakes to avoid when wiring a 400 amp meter base. 1. Insufficient Wire Size. One of the most common mistakes is using insufficient wire size for the wiring connections. A 400 amp meter base requires large gauge wires to handle the high electrical loads. Using wires with a smaller gauge can result in overheating, voltage …Conduit size required for 100, 200, 400 amp service. 400 amp isn't what I'd be considering, but the guy from the power company said running two pair of 200 amp wires would be sufficient.

I use a thirty foot piece of 4/0 or 0000 wire and it gets warm after a day of 275 amp welding, TIG DC. Part of the problem is the ground clamp. I use a very large heavy duty, brass clamp, rated at 400 amps as well. They tend to stay cooler. This helps the electrical connection on the clamp. Make a better contact with the wire.For a 400 amp service, the minimum wire size required is 3/0 AWG copper or 2/0 AWG aluminum. These wire sizes have an ampacity of 400 amps. Voltage drop. Voltage drop is the amount of voltage that is lost as electricity travels through a wire. The longer the wire, the greater the voltage drop.
Now we can calculate the 14 AWG copper wire voltage drop at a 100 ft distance for 15 amp service using the above equation like this: Voltage Drop (14 AWG Copper, 15A, 100ft) = 2 × 100 Feet × 12.9 Ohms × 15 Amps / 4,107 CM = 9.42V Decrease. We can see that the voltage in a 100 ft 14 AWG copper wire drops by 9.42V.The grounding wire size for the main panel can also work for the subpanel, especially if you're dealing with a 100-amp service in both cases. 8AWG or 6AWG will do. Although, you are free to use the same wire size as the neutral and live.
