Hi All
I am currently in Asia (thailand) and recently purchased a used 3 phase Sq D panel. The service I currently have is single phase 220vac 2 wire (hot/neutral). I was reading a topic here that said you CAN wire single phase to a 3 phase service panel but lose a third of the slots for breakers.

I am not bound by NEC here or any other local codes (they possibly exist on paper but in practicality they don't).

With the 2 wire system and I have enclosed photos of the service panel can I wire all three of the phase terminals with the hot leg and then the neutral to the N terminal on the right of the breakers ? I am suggesting to splice off the main with 2 more wires (split bolt connector)so that all the bus bars receive power. Will that allow me the use of all the breaker slots ? I am aware its not conventional and perhaps will receive some comments to that effect. I have a service panel to each one of the floors...basement....first floor and then second floor. Main breaker disconnect is located separate from all the service panels. They are 12 slot SQ D Qo breakers. Please let me know if it is possible (not whether it is code) as im pretty sure its NOT LOL My intent is to expand the number of breakers available on the first floor. In case you are wondering the panel you see cost $100 usd and a new service panel + Main + breakers would be a couple hundred dollars more.


the wiring you see is from the previous contractor and i haven't removed any of it yet.
sorry for the long post all suggestions are welcome.

many thanks
