PANEL UPGRADE QUESTIONS
Panel Upgrade & Sub-Panel Questions
What is the difference between a sub-panel and a main electrical panel?
A main electrical panel distributes power from your electrical service to the whole property. A sub-panel adds extra circuit capacity in a specific area, such as a garage, basement, addition, workshop, EV charger area, or commercial space. Power Blitz can review whether a sub-panel is enough or whether the main service should be upgraded.
When do I need a 60 amp, 100 amp, or 200 amp panel upgrade?
The right panel size depends on your current electrical service, planned loads, available panel space, and the equipment being added. Common triggers include EV chargers, hot tubs, basement suites, major renovations, garage or workshop circuits, heat pumps, and commercial equipment. A licensed electrician should assess the load before selecting a 60 amp, 100 amp, or 200 amp solution.
Can Power Blitz install a panel or sub-panel I found online?
In many cases, yes, but the equipment must be suitable for the installation, compatible with the existing electrical system, and installed according to code. Power Blitz can assess panel specifications, breaker compatibility, service capacity, and installation requirements before work begins.
Does a panel upgrade need ESA notification or inspection?
Panel upgrades, service upgrades, and sub-panel installations often require proper permitting, notification, and inspection steps. Power Blitz plans panel work with safety, code compliance, and ESA-ready documentation in mind so homeowners and businesses are not guessing through the process.
Is a panel upgrade required before installing an EV charger?
Not always. Some properties have enough electrical capacity for a Level 2 EV charger, while others need load management, a sub-panel, or a service upgrade. Power Blitz can assess the existing panel and recommend the safest path before charger installation.
