Hi, we are having some odd electrical behavior where half of our power in the building is not working.
The way the electrician explained our system to me is, the Utility company supplied us with 3 Phase, however we are only utilizing 2 Phases.
BOX 1 which gets 3-phase supply from the Utility company, then passes the 2 wires (labeled PURPLE and ORANGE) to BOX 2. As you can see, BOX 2 is a 2-phase setup.
I noticed that in BOX 2, the GREEN line is HOT, but the RED line is DEAD.
So I traced it back to BOX 1, and noticed a few things. First of all, the PURPLE line coming out of the breaker is HOT, but the ORANGE line is DEAD. So I thought maybe the breaker was bad. However, I then noticed that the LINES 1, 2, and 3 which come from the Utility company --- Line 1 and 2 are HOT, but line 3 is DEAD.
If line 3 is DEAD, will this system not work, despite the fact that I'm only using 2 Phase? I wanted the electrician to come out, but he said I should first call the Utility company to check their connection on Line 3. Once they fix that connection, he says my 2 Phase system should be up and running? You don't think it could just be that the breaker in Box 1 with the Purple/Orange line is bad?
