I'm sitting here reading the tech data sheet for a Siemens type P1 panelboard. I noticed that one of the available breakers listed (Type BGL) has a note #2. Looking at the bottom of the page, note #2 reads:
"Two pole breaker is one phase and neutral, Three pole breaker is two phases and neutral."
What does that mean? I don't have this panel or plan to order it, I just wonder what such a panel would be used for.
