The Difference Between a Placed-in-Service Report and a Certification

When a C-10 electrical contractor finishes installing EV chargers and hands over the keys, most property owners assume the work is done. The chargers are on. They're billing. The electrician left paperwork. What else is there?

Quite a bit, as it turns out. California's commercial EV charger compliance framework involves two distinct requirements that most installers don't address — and most operators don't know exist.

What a C-10 Contractor Does

A licensed C-10 electrical contractor installs the equipment. They pull the electrical permit, run the conduit, connect the panels, and commission the units. Their scope ends at the point the charger powers on and passes basic functionality checks.

None of that constitutes Weights and Measures certification. A C-10 is not authorized to certify commercial measuring devices. That authority belongs exclusively to county sealers and CDFA-licensed Registered Service Agencies under BPC §12532.

What RSA Certification Is

RSA certification is the independent accuracy verification performed after installation. Using NIST-traceable reference equipment, a licensed RSA technician tests each port under load — verifying that the kilowatt-hours the charger measures and bills match the electricity actually delivered to the vehicle.

The testing follows California EPO No. 52 and NIST HB 44 Section 3.40. Acceptance tolerances are ±1.0% for Level 2 AC chargers and ±2.5% for DC fast chargers. If a charger passes, the RSA affixes a tamper-evident seal showing the RSA registration number and certification year.

Certification is what authorizes the charger for commercial service. Without it, billing is a BPC §12532 violation — regardless of whether the equipment was properly installed.

An electrical permit does not satisfy Weights and Measures requirements.

What the Placed-in-Service Report Is

The placed-in-service report is a separate but related requirement. Under CCR §4085, an RSA must notify the county sealer within 24 hours of certifying or repairing a commercial measuring device. This report is the mechanism by which the county W&M office maintains its registry of commercial measuring devices and schedules future inspection cycles.

A property owner whose charger was installed without a placed-in-service report has no documented compliance record. When a county sealer arrives — with no advance notice — and asks for documentation, an installation permit from the C-10 is not a substitute.

Why This Matters in Practice

The sequence matters:

Most EV charger deployments in California complete step one and skip steps two and three entirely. The chargers work. They bill customers. The documentation chain doesn't exist.

When enforcement arrives — through a county sealer inspection, a consumer complaint, or a CDFA referral — the absence of steps two and three is the violation, not the absence of step one.

What ChargeScale EV Provides

ChargeScale EV performs RSA certification and files placed-in-service reports for commercial and public agency EV chargers across Northern California. We close the loop the C-10 left open — providing the accuracy verification, tamper-evident sealing, and county sealer documentation that turns an installed charger into a legally operating one.

If your chargers are on and billing, the question isn't whether they work. It's whether they're certified.
