Abstract
Abstract Multiple meter electrical switchboard apparatus having a plurality of service sections, each including a meter compartment and an adjacent switching compartment. A meter socket and watt-hour meter are mounted in each meter compartment. A switching mechanism and circuit protective devices, such as fuses or circuit breakers, are mounted in each switching compartment. Busbars carrying incoming power are electrically connected to the components in each service section, and each service section has load terminals for making connections to a sub-feed or branch circuit. The apparatus has vertical and horizontal wireways for accommodating cables connected to the load terminals. Each compartment is accessible only through the open front of the apparatus and each is individually covered by a closure member.
