I have an odd situation where there is a 200 amp 240v Delta Service.
Off the side of the meter is a 3 phase 240v 12 circuit 3r panel (Wild Leg on C) that has (3) 3p breakers in it to feed (3) air conditioners. This panel is fed with (3) 3/0's and a #3 Neutral from the meter.The air conditioners are fed 3 phase with with a ground (No neutral required).
There is a 100a 2p fused disconnect below the 3ph meter that has (2) #2's and (1) #2 Neutral off of A and B feeding it (which goes inside and feeds a 1 phase panel for lights and plugs)
I am needing to install another 100 amp 1phase feeder and the only space left is out of the 3ph panel using a 2p breaker on A and B Phase.
As indicated before the Neutral feeding this panel is a #3 which is the same size as the Neutral i will be pulling for the new 100a feed. I feel that the #3 Neutral feeding this panel will be fine since there are only AC Loads coming out of it but it just seems odd to have the same size neutral feeding a panel as the branch neutral I'm fixing to pull. Comments?
