What type service is this?

[Bob Elliott]

I do not have a problem with standard three wire service , but this feed threw me for a loop.

Bottom three are hot with neutral on the right .
Is this three phase?[ as I saw no sign of that service being used in this 3,000 square foot Condo.

Hi Bob,

That is a 3 phase panel, the distribution is 120/240 though.

If you had taken your voltmeter and put it across breakers 1 & 3 and had the same reading (240 or 208 ) across breakers 1 & 5, that should have given you the evidence that it was 3-phase. Or the voltage would have been the same across the main lugs a-b & a-c.

3000 sq ft... nice! You makin' your way over to the Trump Towers now?

[David A. Andersen]

But is it Delta or Wye?

yep... nothing was proved that the voltage was 120/240. Unless Bob comes back with the answer.

Yeah, that was my thought to, but after chatting with Bob it turns out that it was a former office space used as a residential condo.

Thanks guys, and especialy Gerry for the call.
Has two furnaces and two condensors, plus was used as an office before hand.

I suspected ,but now feel it was just put in to handle a bigger future load.

Nice size place with elevator to the unit and roof rights for future decking.
I do not do factory commercial (yet) and have minimal knowledge in three phase.
That Delta stuff is gonna be a big learn when I do.

Makes perfect sense then.

Bob...Mike W pointed it out and you may already know this but in the one label photo, see the box labeled "Ø" with the 3 below it? The "Ø" stands for 'phase'.

[Bob Elliott]

I did not know the symbol 0/ (how did you do that?)

But I saw the 3 and the 4 and kinda figured that was a damn good clue.

Chastise me but I just used my ticker on it.

Got the one which reads current on one side and was trying to wrap up .(another no no...yes should have used the meter)

I knew all three were hot but just could not figure why there was no three phase devise , which confused the issue for me. Duh!

There's a whole plethora of letters, numbers and symbols available to you. Do you know how to type °, ø, ¼, ™, õ, ©, x³, .....etc, etc?

[Greg Fretwell]

Mr Whitt put his finger on the answer, 3 phase 208/120 Wye. You will see 208 between phases and 120v to ground from each of them. The other tip off is the rotating red, black, blue conductors on the breakers.
If it was 3p Delta, code says the hign leg (usually B) coming in has to be orange too.

There are a few ways.

The copy/paste method is the easiest I've found. Ø
Alt. keys are the next.
