Electrical Panel Upgrades in Tempe, AZ

Capacity, Measured Before It Is Quoted | AZ ROC License #167102 (CR-11) | Family-Owned Since 2001 | Free Estimates | One-Year Warranty

Tempe exists because somebody worked out how to get power to a site. In 1870 that meant a water claim and a canal. The arithmetic has not changed as much as you would think.

RSB Electrical has been upgrading panels across the East Valley since 2001. On a service change, the permit and the utility scheduling are a larger share of the work than most homeowners expect, and Sharee runs both of them so you are not the one chasing anybody.

Panel Work In Tempe

A Service Upgrade Is a Capacity Question, and Capacity Questions Built This Town

The settler who founded Tempe filed for ten thousand inches of Salt River water in November 1870, alongside a homestead claim on a hundred and sixty acres in section 15. Two years later, he opened a store and laid the foundation for a flour mill, and a canal was cut along the base of the butte to bring water in to turn the grindstones.

Work out how much energy the site needs, then build the thing that delivers it. The mill was finished in 1874, four years after the water had been secured.

A panel upgrade asks the same question with different units. How much does this property actually draw, what is the service rated to carry, and what has to change to close the gap? We do that calculation before quoting, and we show it to you, because a panel is one of the easiest things in this trade to sell to somebody who does not need one.

Tempe Conditions

The Town That Started by Cutting a Canal to Turn a Wheel

The detail worth keeping from Tempe's founding is not the ferry or the store. It is the canal. Nobody built that mill and hoped. The water claim was established in 1870, and a channel was later extended along the base of the butte specifically to ensure enough flow to turn the grindstones.

Supply first, then the machine that uses it. That order is the entire discipline of a service upgrade, and it is also the order that is easiest to skip. Choosing a box before establishing what the property and the utility can support is how a job acquires a second visit.

So we do it in the order the canal was dug. We calculate demand, confirm what the service can carry, establish what the utility needs, and only then discuss equipment. On older Tempe lots, that sequence earns its keep because the service entrance is often in an awkward location.

The mill was finished in 1874. The supply question had been settled four years earlier.

What We Look For

The Two Questions a Panel Job Actually Turns On

Everything below sorts into one of two piles: what the box is doing, and what the supply behind it can give you. Bad panel advice comes from answering only the first.

Supply: what the service is rated to carry today

Not what the main breaker says, and not what the previous owner believed. The rated capacity of the existing service sets the ceiling for every subsequent plan, and it is the first number we establish.

Supply: where the meter sits and whose it is

On attached property and on older Tempe lots, the meter can sit in a gang, on a party wall, or somewhere you are not free to relocate on your own. That never stops an upgrade. It does decide the routing, the length of the run, and occasionally who else has to agree, which is why it belongs in the estimate.

Supply: what the utility requires at this address

Clearances, meter position, the shape of the entrance. These are settled with the utility before a box is ordered, because discovering them on installation morning is how a single visit turns into two.

The box: heat marks, discoloration or scorching inside

Discoloration at a lug is a connection announcing that it has been running past what it can hold. The metal keeps that record whether or not anybody reads it, and nothing about it improves with time.

The box: breakers that have started refusing loads they carried for years

Thermal cycling wears them out, and an Arizona exterior enclosure gets a great deal of it. When a circuit that ran an appliance for a decade starts objecting, the appliance is seldom what changed.

The box: water staining or corrosion inside an outdoor enclosure

Whatever gets into an enclosure stays in it, and what it does to a bus bar happens somewhere nobody has any reason to look.

Both at once: nothing left for what you are about to add

A charger, a spa, a workshop, a second kitchen circuit. Reshuffling and tandem breakers genuinely solve some of these, and where they do we will say so. Past a point, the honest answer is more service, and that is a supply answer wearing a panel costume.

How The Work Goes

Settling the Supply Side Before Anything Else

We find out what your service actually is, not what it looks like

A meter on a wall does not tell you what is behind it. Where a property shares a service, sits in a stack of meters, or was divided at some point in its life, the supply arrangement decides what is possible before anything about your panel matters.

Who has to agree, and who has to be told

On a single house, that is you and the utility. Where the service equipment is shared, an association or a building owner is usually in the sequence as well. Finding that out first avoids a quote that cannot be acted on.

Then the load calculation, and you keep the working

Fixed appliances, cooling equipment, and whatever is being added, against what the service delivers. Where the answer is that the existing service is adequate, that is a real answer, and you have the arithmetic to show it.

The interruption is requested for you, with a realistic window

Sharee files the permit and asks for the outage. The window a supplier gives is theirs, not ours, and you get the actual one rather than an encouraging one.

Every circuit landed, identified, and a directory somebody can read

Including the ones that were unlabeled when we arrived. A directory that names rooms and appliances is worth more in ten years than the panel itself. Our work carries a year on labor and materials.

How We Work

What Makes a Panel Quote Worth Trusting

You are handed the arithmetic, not the conclusion

The load calculation comes to you as a document. Where it says the existing service is adequate, that is what we tell you, and we have left panel work on the table on exactly that basis.

Nothing is ordered before the supply side is known

The entrance is measured, the meter position is confirmed, and the utility's requirements are in hand before equipment is specified. That order is why these jobs so rarely need a second visit.

Tempe Electrical Panel Upgrades Faqs

Panel Questions From Tempe Owners and Residents

1.My panel is in a shared area. Does that change things?

It changes the sequence rather than the work. Access, notice to whoever manages the space, and sometimes an association's own approval all come before the electrical part. None of it is difficult, and all of it takes longer than people expect.

2.Who talks to the utility, me or you?

We do, for the permit and the interruption. What we cannot do is hold an account in your name, so anything related to the account itself stays with you. We will tell you plainly which side of that line any given step falls on.

3.Does the meter or the service entrance have to move?

Sometimes, and it is the finding most likely to change the shape of the job. Clearances, the condition of the entrance, and where the supply arrives all bear on it. It is established at the assessment, because discovering it on the day derails the schedule for everybody.

4.The panel looks original. Is that itself a reason to act?

Not by itself. An original panel that reads well and has capacity is doing its job. What an original panel does raise is the chance that the service was sized for a household with far less in it, and that is the question worth putting to the arithmetic.
