Upgraded service
Prior to service being changed or relocated to supply new or existing load, contact NV Energy. All service entrances being upgraded, (increased main breaker ampacity) or relocated must be brought up to current city or county code and specification requirements.
Removal of service
Contact your local NV Energy office with requests for the removal and or relocation of existing electric facilities. Due to normal schedule times for NV Energy construction crews, a minimum of two weeks notice should be given to NV Energy prior to the date the facilities are to be removed and or relocated.
Number of services per premise
All new homes must be wired for one meter. Existing homes adding load requiring an upgrade of facilities must be wired to be served through one meter.

The Customer shall provide a bus or bar in the section for grounding and bonding as per NEC and provisions for 3 element metering.

Master Metering Needs Scrubbing by Standards
Residential apartment complexes, condominiums and other multiple residential buildings shall not have a master metering installation unless building(s) have centralized air conditioning, ventilation and/or heating systems and meet ACC rules and regulations.
Master metering will not be installed on existing or new permanent residential mobile home parks. Visit the NV Energy office in your area for more detailed information or consult ACC rules and regulations.
