All sales be on the basis of meter measurement except when other basis is provided in the filed rates or when the nature of the usage is such that the consumption may be readily computed. (2) Master Metering. (a) Each dwelling and commercial unit in a multi-dwelling unit residential building, mobile home park or commercial building, the construction of which has commenced after the effective date of this rule, shall have installed a separate electric meter, except that individual unit metering will not be required: 1. Where commercial unit space requirements are subject to alteration with a change in tenants as evidenced by temporary versus permanent type wall construction separating the commercial unit spaces; 2. For electricity used in central heating, ventilating and air-conditioning systems; 3. For electric back-up service to storage heating and cooling systems. (b) For purposes of this rule, “dwelling unit” means a structure or that part of a structure which is used or is intended to be used as a residence or a sleeping place such as a house, a mobile home or an apartment, but does not include multi-dwelling facilities used principally for temporary occupancy such as hotels, campgrounds, hospitals and dormitories. (c) For purposes of this rule, “constructed’’ means totally newly built or renovated to the extent that general rewiring is necessary.
