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.

I has been a long time, but I seem to recall something similar being required for gasoline pumps. I haven't worked with that stuff in years, so don't quote me on that.

That may be the panel that the AFCI's go into that do NOT come with neutral pigtail, only a load neut/line termination.

Time permitting, I have to read more on this

It's where a neutral is req. to be switched, and the accessory requires one additional pole space just like a shunt trip.

Its a switched neutral 2 or 3 pole breaker, used to break all conductors. Its just a switch on the neutral side as far as I know. Use them all the time in gasoline installs

This breaker is to be used for gasoline pumps or other places where you need to brake the netural also when you turn off the circut

They should just run the pumps on 2-wire 240V and not worry about switching a neutral since there won't be one (at least in North America).
