For the follwing scenerio, are the requirements of 230.70 and 230.90 being statisfied?
240V, 3-wire, single-phase service. From the meter socket enclosure, two ungrounded conductors and one grounded conductor are brought to a 60A rated 2-pole main lug panelboard. There, one single pole 15A breaker is installed to supply a single piece of equipment. No breaker is installed on the other leg.
In addition to this arrangement, the panelboard is marked with the following label:
This panel is suitable for use as service equipment when a main breaker is installed or when not more than two branch circuit breakers are installed and is not used as a lighting and appliance panelboard.
