Commercial service upgrade: increase the building’s service after the load has been shown to need it — not a default to more amps
A commercial service upgrade is the increase after the calculation says the existing service is short. It includes the gear on your side of the meter and, on most jobs, a scheduled disconnect with the utility.
The calculation first
New HVAC, a kitchen, process load, or a tenant that outgrew the service. The increase is after that need is established.
The gear is the problem instead
Obsolete or damaged equipment, load still fine, is commercial panel replacement.
The service is fine, the floor is not
That is a commercial subpanel. A multifamily building service is multifamily service upgrade — not a stack of residential 200-amp jobs.
Commercial service upgrade: you provide the new gear; the utility schedules the shutdown
A commercial service increase is new switchgear plus utility coordination. The switchboard or panelboard, the service-entrance conductors, and often a CT cabinet are yours to install. The utility handles disconnecting and reconnecting the power on its own schedule — and the building usually has to keep running while the work happens.
-
Switchboard, not just a panel
A larger service often means a switchboard or a CT-metered service, not a bigger panel. The gear, its rating, and the room it needs are the real scope.
-
The utility’s process
The service application, the metering change, and the scheduled disconnect run on the utility’s timeline. Building the job around that date is half of getting it done.
-
Occupied through the work
Most upgrades happen on a working building. Temporary power, phasing, and a short planned outage keep the tenant open while the service changes.
When a commercial service upgrade isn’t the right job
A proven capacity increase is this job. Failed gear at the same amperage, or a multifamily building service, are not.
The can failed and the amperage is staying
That is commercial panel replacement.
Apartments or condos as a property
That is multifamily service upgrade.
Commercial service upgrade: utility, permits, and this job
This work often involves the utility or a permit. The address decides which office and which provider — not a generic Sacramento paragraph copied onto every service.
SMUD, PG&E, or Roseville Electric may need a disconnect or a meter appointment if the service equipment is involved.
We pull the permit for the city or county that actually covers the address.
A dimmer, a switch, or a lighting control does not get this chapter — the utility is not in that job.
Commercial service upgrade questions
Is more amps the default?
No. The increase is after the load is shown. If the gear is the problem, that is commercial panel replacement.
Does the utility have to be involved?
Usually. A service increase on your side of the meter still needs a scheduled disconnect on most jobs. We coordinate that.
Can a subpanel skip this?
If the service still has headroom, a commercial subpanel is the distribution job. This job is when the service itself is short.
This is an apartment building.
The building service, house meters, and the utility on one schedule is multifamily service upgrade.
What is considered an electrical service upgrade?
Raising capacity at the service, the meter, or the main distribution so the calculated load fits. We coordinate the utility.
