Err, I meant "skip the neutral wire". It's still grounded. And there are normally significantly more covers over the panel than this, there were a dozen screws I had to remove to expose all of this. :) This is a much smaller scale panel though, not far up from a typical home system. The more current you start talking about, the more isolated everything becomes until you wouldn't even be able to see the bus bars like in this one.
are "Residual-current device" (Fi in German) are common in us?I use for servers "Residual-current device" and circuit breaker integrated in one device; but I try to use the more expensive pulse tolerant ones.
Kind regards, Ingo Flaschberger
