Re: 400 amp single phase service wire size residential

I failed to mention that some time ago I had a conversation with the manager of an electrical subcontracting company. I asked him why I had not seen 400 Amp service panels in residential applications. His answer was that the conduit size required to accommodate conductors for a 400 Amp service were so large that it would not fit between normal 2X4 Studs and the cost of one 400 Amp distribution panel was much higher than two 200 Amp Panels. At that subdivision, at each residence, the electrical contractor installed one rain tight combination 400 Amp Panel and Meter Can outside with two 200 Amp breakers each feeding two 200 Amp distribution panels via separate conduits.
