    napaka delikadong design nito.. 400V ang ipapasok mo sa residential units (studio/1BR/2BR/penthouse)? kahit may L-N ka na 230V.. ung panelboard mo is expose sa 400V L-L. Pinaka safety na set up is ung meter center ang naka 400 V tapos naka L-N lang ang ppasok sa mga residential units.. mahal din ang ganyan setp oblige bumile ng 3Phase kwHR meter instead na single phase kWhr lang hindi approve kay meralco yan..

    Di ba sa NEC ay 1500VA ang small appliance at ang voltage ay 120V? Sa atin ay 230V sa small appliance bakit hindi 3000VA. Comparison: NEC 1500VA / 120V = 12.5A gamit nila 20A CB . Sa atin kun 3000VA / 230V = 13A, gamit natin 20A CB.
