How It Works
We keep things straightforward. Here's what to expect when you work with Klein Electric LLC on a panel upgrade.
We start by reviewing your current panel, your electrical load, and what your home or business needs now and down the road. This shapes the scope of work before anything else.
Once we understand what's needed, we walk you through the upgrade plan, including panel size, breaker configuration, and any permit requirements specific to your municipality in Maine.
Panel upgrades require permits in Maine. We handle coordination with the local inspection authority so the work is done to code and passes inspection without hassle.
Our crew completes the panel swap efficiently, minimizing downtime to your property. We treat your space with care and leave the work area clean when we're done.
After installation, the work is inspected by the local authority. We're present for that process and handle any follow-up needed to get the job officially closed out.
Frequently asked
Common questions get answered quickly so the page feels more trustworthy before someone reaches out.
Q1
Common signs include frequently tripping breakers, a fuse box still in use, flickering lights, or plans to add high-demand equipment like an EV charger or new appliances. An electrician can assess your current capacity and tell you where you stand.
Q2
Most modern homes are upgraded to 200-amp service, though larger properties or commercial buildings may need more. The right size depends on your current usage, square footage, and future plans. We assess this before recommending anything.
Q3
Yes. Electrical panel upgrades require a permit and inspection in Maine. Klein Electric LLC coordinates the permitting process and ensures the work meets code before inspection.
Q4
Most panel upgrades are completed in a single day. More complex commercial jobs or situations involving service entrance work may take longer. We'll give you a realistic timeline before the work begins.
Q5
Yes, there will be a period without power while the panel is being swapped. We schedule and work efficiently to keep that window as short as possible, usually a few hours for a standard residential upgrade.
Q6
Often, yes. If your current panel doesn't have the capacity for an EV charger or solar tie-in, a panel upgrade is usually the first step. We can plan both at the same time to avoid doing the work twice.
Q7
Yes. Klein Electric LLC serves both residential and commercial customers throughout Maine. Commercial panel work involves different load requirements and code considerations, which we're experienced in handling.
Q8
We serve customers statewide, including Oakland, Augusta, Waterville, Bangor, Winthrop, Freeport, Belfast, Rangeley, and surrounding communities. If you're in Maine, reach out and we'll let you know about scheduling in your area.
