I have a customer that has an existing 3 phase service on a building that is going to be torn down. The only thing it is feeding that needs to stay is a 20 amp. 240 circuit that feeds a propane tank for campers etc. What we are thinking to do is set a weather proof panel beside the meter after the building is torn down and use the appropriate mounting. Think panel will have the 20 amp double pole in it and also a50 amp DP Circuit for a 240 volt outlet and a single pole breaker for a 120 volt outlet. My question is : I'll have total of 3 breakers. The smallest 3 phase 200 amp. WP Panel I can get is 18 circuit. I think this amount breakers would qualify for a main lug panel, but there are spaces for more. What would be your thoughts? Thanks
