a fourplex building, two apartments upstairs, two offices downstairs, the meter base has four 200 amp breakers. From there are 3 wires to each of 4 inside panels, with neutral and ground connected together in each panel. In my remodeling, should I address these not being 4 wire, with isolated neutral ? The two offices on the ground floor are less than 10' of wire and wouldn't have required outside disconnects, correct ?
