Alright. Neutral and ground are tied together at the first point of disconnection, and seperate thereafter.
Or so I thought.
What about mobile homes, with a breaker built into the meter base? I've been seeing 3-wire connection from said disconnect to the breaker box. Are all the ones I'm seeing illegal?
What about an apartment building? The place where I grew up, built in 1980, has, at the end of each building, six meters with main breakers built-in. 3-wire cables go from there to the breaker boxes in the apartments.
Fill me in.
