Summary
Livermore adopts the 2023 National Electrical Code as amended by the California Building Standards Code, and it is unlawful to connect or energize any electrical wiring or equipment requiring a permit without the building official's authorization; the official signs the permit card and clears the utility to connect once the work passes inspection.
A. It is unlawful for any person, firm or corporation to make connection from a source of electrical energy or to supply electrical service to any electrical wiring or equipment, for the installation of which a permit is required, unless authorized by the building official. B. When the electrical wiring and equipment is found to be in conformity with the provisions of this code, the building official shall indicate such approval by signing and dating the permit card and, if the building or premises containing the electrical installation has been approved by the building official for occupancy, the building official shall notify the serving electrical utility of such approval and shall authorize the connection of the installation to the source of supply.
Full Breakdown
030 keyed to the 2025 California Electrical Code section numbers. 040 makes it unlawful for any person, firm or corporation to connect a source of electrical energy or supply electrical service to wiring or equipment requiring a permit unless the building official has authorized it (subsection A). Once the wiring and equipment conform to the code, the building official signs and dates the permit card and, once the building is approved for occupancy, notifies the serving electrical utility to authorize the connection (subsection B). For a building not yet approved for occupancy, the building official may authorize a temporary connection solely for testing equipment, providing light to finish construction, or similar purposes, but only if the owner has filed a statement certifying the building will not be occupied except for work necessary to complete it (subsection C). 12(A)-(E), and specifically extends that requirement to panelboard changeouts.
Violations & Fines
Connecting power to permit-required wiring without the building official's authorization is unlawful under Section 15.08.040(A); the building official withholds the signed, dated permit card and the utility-connection notice until the installation conforms, and an owner who obtains a temporary construction-only connection under subsection C by certifying the building won't be occupied, then occupies it anyway, violates both the certification and the underlying unlawful-connection provision.
