Commercial customer has 3 tenants all all 3 3 phase main panels with branches are in tenants first floor tenants closet .Second floor tenant is complaining about access to panel . My plan is to run a 70 amp sub panel to second floor and relocate 110 volt branch circuits for lighting and receptacles about 15 circuits and leave hvac circuit in main panel.Im trying to decide if I should run a 3 phase sub or single phase if I should run conduits over drop ceiling or romex( allowed in NJ) and if I should pull out the existing wiring from the main panel and junction outside or just make a bunch of splices in the panel.
