There's a calculation that settles whether your service is genuinely the constraint, and it takes a conversation rather than a site visit to start. Sometimes the answer is a full service upgrade. Frequently it's a subpanel, a few added positions, or a straight panel replacement on the same service size — all considerably cheaper.
Beacon Electric assesses, designs, and installs panel upgrades and service changes across Greenbrier, TN. Call and describe what you're adding, and we'll tell you which of those four answers is yours before anyone quotes anything.
Almost everybody who asks for a panel upgrade asks for it in amps. "I think I need to go to 200" is the most common opening sentence in this trade, and it's answering a question that hasn't been checked.
Service capacity is one of four separate reasons to change a panel, and it's the one least likely to be your actual constraint. Each needs a different diagnosis, carries a different scope, and costs a different amount.
Whether the incoming service can supply what the property demands. Established by calculation, not by opinion — and this is the only one of the four that's about amperage.
Whether there are physical positions left for the circuits you want to add. A completely full panel on an entirely adequate service is extremely common, and it isn't a capacity problem at all.
Whether the panel itself is sound — the enclosure, the bus, the terminations, the breakers. Panels corrode, overheat, and in some cases were problematic when new.
Whether the installation has the protective devices current practice expects. Arc-fault and ground-fault protection, surge protection, and correctly matched breakers are safety functions, not features.
A panel upgrade is planned work. The following are not, and they need a same-day call rather than a quotation.
A panel is the single point through which every circuit in the building passes, so a fault there isn't confined to one room. If any of those apply, don't open the panel — call now.
This is the measurement that should precede any quote, and it's why we ask what you're adding rather than what amperage you want.
A load calculation is a structured arithmetic exercise. It takes the property's floor area, its fixed appliances, its heating and cooling, its cooking and laundry equipment, and any new loads you're planning, applies the demand factors reflecting how those things actually get used, and produces a number: the demand this property places on its service.
Compare that against the service you have, and you have an answer rather than an impression.
Extremely common. You don't need more amps, you need more positions. That's a subpanel, tandem breakers where the panel permits them, or consolidating circuits that were split unnecessarily. A far smaller job.
Also common. The upgrade is about condition and protection rather than capacity — frequently a panel replacement on the same service size, which is a different scope and price from a service upgrade.
This is the real service upgrade, and it involves your utility, the meter, the service entrance, and the grounding and bonding system — not just the box on the wall.
Replacing a panel is one job. Increasing the service that feeds it is a larger one including utility coordination. Being told which you need — with the calculation behind it — is the difference between a considered decision and an expensive assumption.
Ask for the calculation. Anyone quoting a service upgrade should be able to show you why.
Sorted by reason, because the reason determines the scope and the price.
The calculation shows headroom, the panel is sound, positions are available, and the protective devices are in place. In that case your money is better spent elsewhere — and you should be told so plainly.
This is the part of a panel upgrade that never appears in the customer's mental picture of the job, and it frequently accounts for a meaningful share of the scope.
A panel doesn't just distribute power. It's the reference point for the entire earthing system — the thing that makes protective devices operate correctly when a fault occurs.
Which means a panel upgrade almost always involves inspecting, and frequently correcting:
Rods, plates, or the connection to metallic water piping — whether it's intact, correctly sized, and properly connected.
Water and gas piping bonded so a fault can't energise them.
Correctly bonded at the service equipment and correctly separated everywhere downstream. Getting this wrong is a common finding in older or amateur-modified installations, and it undermines the protection the whole system depends on.
Which changes when the service size changes.
None of that is padding. A larger panel on an inadequate earthing system is a bigger distribution board attached to a weaker safety foundation. If a quote doesn't mention grounding and bonding at all, that's a question worth asking.
So there are no surprises on the day.
Replacing a panel means the property is de-energised for the working portion of the job. Domestic panel changes are typically a day; service upgrades involving the utility can span longer or require a return visit for reconnection.
Where the service itself changes, the meter and supply side belong to your utility, and their scheduling is part of the timeline rather than something an electrician controls.
A panel or service change is notifiable in most jurisdictions and is inspected. That's protection for you — an independent party confirms the installation. Work done without it creates problems at sale, at insurance renewal, and at the next electrician's visit.
Every circuit traced, transferred, and labelled properly. A correctly labelled panel is worth having for the next twenty years, and it's frequently the first accurate schedule a property has ever had.
Once the old panel is open, pre-existing conditions become visible — undersized conductors, damaged cable ends, incorrectly shared neutrals, circuits never terminated properly. Those get reported with options rather than absorbed silently or used as leverage.
The area around the panel is reinstated to a sensible standard, though a panel change is not a decorating job and shouldn't be sold as one.
Distinct from an emergency — these indicate an assessment conversation rather than a same-night call.
The load calculation decides whether you need capacity, positions, a sounder panel, or nothing at all — and we'll tell you plainly which.
Capacity, space, condition, and protection are different problems with different prices.
If your service has headroom and your panel is sound, a subpanel or a few positions solves your problem for a fraction of the cost.
It's what makes every protective device in the building work.
Every circuit traced and identified, because an accurate schedule makes every future job faster and safer.
An independent inspection is the only external confirmation you'll ever get that what's behind the cover is correct.
Electricians serving Greenbrier, TN.
Decisions worth making before the day rather than during it.
The marginal cost of a few spare positions during the work is small. Finding them later is not.
An EV charger, heat pump, air conditioning, workshop, hot tub, or conversion — even as a maybe. Capacity planned for is cheaper than capacity retrofitted.
If it's in an awkward or non-compliant position, the upgrade is the moment to move it.
It's the cheapest it will ever be to fit while the panel is open.
They matter at sale, at insurance renewal, and to whoever works on the property next.
You'll have the calculation, the recommendation, and the price before work begins — with the scope stated plainly enough to compare against anyone else's quote line for line.

A load calculation takes your floor area, fixed appliances, heating, cooking, and anything you're adding, and produces a demand figure to compare against your existing service. Many properties asking for 200 amps have adequate capacity and a full panel, which is a different and cheaper job.
Not necessarily. Full is a space problem. Capacity is how much the service can supply, and the two are unrelated — you can be out of room on a service with substantial headroom. A subpanel frequently solves it.
A panel replacement changes the distribution equipment on the same service size. A service upgrade increases the incoming supply itself, involving the utility, the meter, the service entrance conductors, and the earthing system. Different scopes, timelines, and prices.
Yes in most jurisdictions, and you want one. Inspection is the only independent confirmation that what's behind the cover was done correctly — and unpermitted panel work causes problems at sale and at insurance renewal.
For a domestic panel change, typically the working portion of a day. Service upgrades involving the utility can be longer or need a return for reconnection — and you'll get a realistic figure before the date is set.
It depends on the panel. Some older types genuinely have documented failure histories; others are simply obsolete with unreliable replacement breakers. You should be told which applies to yours, and shown why, rather than given a category verdict.
Because it's what makes protective devices work. A panel is the reference point for the earthing system, so an upgrade almost always involves inspecting and often correcting electrodes, bonding, and neutral-ground separation.
Frequently. Undersized conductors, damaged cable ends, shared neutrals, and poor terminations become visible when the old panel comes off. Those get reported with options and prices, not absorbed quietly or used as pressure.
Sometimes — the calculation decides. Load management devices can also allow a large load on a service that couldn't otherwise support it at full output. Worth asking before assuming an upgrade is required.
It's the cheapest it will ever be while the panel is open, and it protects everything downstream. Worth considering as part of the work rather than a later retrofit.
It's rarely a feature buyers pay a premium for, but a sound, labelled, certified panel removes an obstacle at survey — and an obsolete or unsafe one is a negotiating point against you.
Not while the panel is out. You'll be without power for the working portion of the day, so plan around refrigeration, work, and anything time-sensitive.
Capacity, space, condition, and protection are four different reasons to change a panel, and only one is about amps. The load calculation settles which applies to you — and sometimes it settles that none of them do.
Beacon Electric calculates before quoting, separates a panel replacement from a service upgrade so you can see what you're buying, treats grounding and bonding as part of the work, and leaves you with a labelled, inspected, certified installation.
