Why 200 amp service upgrade comes up in Nampa
Nampa has grown quickly as families move west from Boise, and owners of older homes north of downtown and around Lakeview Park are adding central air, heat pumps, hot tubs, shops and EV chargers to houses that were built with 60 or 100 amp services. A 200 amp upgrade usually includes a new meter base and service entrance, and homes on acreage often add a subpanel for a detached shop or barn. Idaho Power schedules the disconnect and reconnect.
Permits come from the City of Nampa's building department, and Idaho electricians are licensed through DOPL.

200 Amp Service Upgrade in Nampa: questions
Do I need a permit for 200 amp service upgrade in Nampa?
Usually, yes. Electrical permits inside city limits come from the City of Nampa's building department; areas without a local program are handled by the state. Idaho licenses electricians through the Division of Occupational and Professional Licenses (DOPL). The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Nampa?
If the work affects the meter or service, the electrician coordinates with Idaho Power, which owns the meter and service drop.
Do I need 200 amps for an EV charger?
Not always. A load calculation may show that a 100 or 150 amp service can support a charger, especially with a lower charging setting or a load-management device.
How long does a 200 amp upgrade take?
The installation is often one day, but utility scheduling and permits can add days or weeks.
Does the utility charge for a service upgrade?
Some utilities charge fees or require their own work on the service drop. Policies vary, so ask your utility.
Is 400 amps ever needed?
For very large homes or homes with electric heat, pools and multiple EV chargers, a larger service may be justified by the load calculation.
