This last method needs more discussion. To bond one end of the service raceway to the service neutral conductor, you must use a listed bonding wedge or bushing with a bonding jumper. Size it per Table 250.66, based on the area of the largest ungrounded service conductors within the raceway [250.102(C)].Their electrician of choice is telling us that we're going to need to upgrade to 400 Amp service or run a second 200 Amp service. I find this hard to believe, but these guys usually know what they're doing. Running new utility wire from the street will be costly I'm sure, not to mention trenching or a new pole etc.A 50 amp sub panel will require at least 3 to 6 AWG wires. Here, I considered the distance around 55 feet. If the distance is longer, I suggest you use thicker and lower gauge wires. If the sub-panel distance from the main panel is 150 or 200 feet, you can use 4 AWG copper or 3 AWG aluminum or copper-clad wires.The NEC recommends using 6 AWG copper and 4 AWG aluminum wires for cable distances of 100 feet or less. For longer distances, such as 200-foot cables, you'll need to use larger wires, such as a 3/0 AWG copper wire or a 4/0 AWG aluminum wire. These larger wires will account for the voltage drop and keep your 50-amp circuit running smoothly.For a 400-amp service, you will need a wire size of at least 350 kcmil for copper wires or 600 kcmil for aluminum wires. It’s essential to adhere to the National Electrical Code (NEC) and local regulations, and consult with a qualified electrician to ensure proper installation and safety.As per new code the electrical panel ground wire or bond wire size is #6 AWG. This applies for service entrances from 100 amp up to 400 amp. Two ground electrodes, or a ground plate must be hooked to this wire to ensure it has a proper earth ground. Electrical Panel Ground Wire-How to Install and Maintain a Ground Wire in Your Electrical PanelHere's what I'd do: -go to supplier pull 400A meter base and panel out of their boxes. -check: temp ratings, AL/CU rating, dual vs single lug. -use that info and T2 to choose wire size and parallel vs single run, keeping 12-108 in mind.

Check Details. 100 amp service wire size chartA 200-amp service with 125 ft run using 3% allowable voltage drop. For 3 AWG copper wire, k = 21 and allowable amps = 205. Using the formula: Neutral Wire Size =2 × 200 × 125 × 21205 × 0.03= 2 AWG. Therefore, the minimum recommended size is 2 AWG copper wires for this 200-amp service with a 125-foot run.If the service wires were 1 foot long, the lives could be #2 (because it's a service, subpanel feeders need #1) and the grounds could be #6. AWG is sized exponentially, so "4 AWG difference in size" is always a factor of 2.52. So take the "kcmil" size of the hot wire you choose, divide by 2.52, and choose a ground wire with that kcmil or larger ...You are correct that 600kcmil is the right size for using a single wire per leg for the service entrance, though -- this gives you 340A at 75°C, just enough to meet our 332A requirement. Furthermore, it is about $0.50/ft cheaper at the time of this writing than the parallel conductors, and also takes up slightly less conduit area, albeit not ...What Size Ground for 100 Amp Service. 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.
