Ground wire size for 400 amp service
For the grounding electrode conductor size, using NEC table 250.102(C)(1) 4/0 Al requires #4 copper. 3/0 Al requires #6 To attach the grounding electrode conductor to the building foundation the building needs to be inspected prior to the foundation being pored to answer correctly.The wire size needed for a 15 Amp circuit will depend on how far the circuit travels. For example, if a circuit will only use 25 feet or less, a 14/2 with ground will work just fine. But if that same circuit was closer to 150 feet long, you would need #8 gauge wire to avoid the voltage drop.However, there are wildly different theories and requirements on what size UFER ground is required. We have local jurisdictions require 1/0 for a 400A service while others require #2. We have seen plans from engineers specify 3/0 for a 1200A service and a few specify 500MCM for a 2000A service.
