Panels
Electrical Panel Upgrades
100A to 200A conversions for houses that outgrew their service.
What the job involves
A panel upgrade is the job that quietly unlocks everything else in the house. Once the service is sized correctly, the charger, the shop, the heat pump, and the hot tub stop competing with each other.
The process is the same every time, which is what keeps it predictable. Doing it right means opening more than the one box that is giving trouble. The fault is rarely where the symptom is.
How we handle it
- Load calculation against the actual connected load, not a rule of thumb
- Utility coordination for the disconnect and the reconnect
- New grounding electrode system and bonding brought to current code
- Every circuit identified, labeled, and re-landed on the correct breaker
Doing this in the White Mountains
Winter here means well pumps, heat tape, and space heaters all landing on a service that was sized decades ago.
Elevation, weather, and the age of the housing stock all change how this work goes here compared with a valley city. Equipment ages faster in this sun, monsoon surge is a real load on the system, and a lot of these houses were built as seasonal property and are now carrying full-time demand.
We would rather find the actual fault than sell you a part that might fix it.
Bus bar rating is the real ceiling
People talk about a panel as though the main breaker is the whole story. It is not. The bus bar, the metal spine the breakers clamp onto, carries its own rating, and that rating is what actually limits the enclosure. A 200 amp main breaker sitting in a panel with a 125 amp bus is a combination we still find, usually because somebody replaced the main and never read the label inside the door.
The label matters for a second reason. Most residential panels allow the sum of the branch breakers to exceed the bus rating, because no house runs everything at once, but they also set a limit on how far past it you may go. That number is printed on the panel and it is enforceable.
So when we look at whether a panel can take another circuit, we read the bus rating, the main breaker, the number of usable spaces, and the manufacturer’s listing together. Those four things decide the answer, and only one of them is visible from the front.
Working clearance and where a panel can live
There is a defined volume of empty space that has to exist in front of every panel, and it is bigger than people expect: roughly three feet of depth, a width of at least thirty inches or the width of the equipment, and clear headroom to about six and a half feet. Nothing stored in it, no shelving, no water heater crowding the side.
That rule exists because somebody eventually has to stand in front of that panel and work on it live, or shut it off in a hurry with one hand while getting clear with the other. A panel behind a stack of totes in a crawlspace fails both of those tests.
Panels also cannot go in clothes closets or in bathrooms. When we relocate one during a service change, the new location is usually chosen around these rules first and convenience second, because the rules are the part that cannot be negotiated later.
Permits, utilities, and the day itself
Anything touching the service involves the utility, and that coordination sets the schedule more than our availability does. The meter has to be pulled, the work done, and the meter reset, and those are appointments somebody else controls.
Plan on the power being off for most of a working day on a panel or service change. We can sequence it to land where it hurts least, and in most cases we can keep a refrigerator circuit alive on a cord while the main work happens.
The permit and inspection are part of the job, not an extra. On a service change the inspector will look at the grounding electrode system, the bonding, the working clearances in front of the panel, and the labeling. All four of those are places where corner-cutting shows immediately.
What you get
- LicensedC-11 #192532 and R-11 #192533
- PriceFirm, before the work starts
- Who shows upThe person who quoted it
- PermitsHandled where the job needs them
- AfterLabeled, documented, and cleaned up
The breaker is not the problem. The breaker is the thing telling you there is a problem.

Breakers have to be listed for the panel
A breaker that physically snaps into a panel is not automatically a breaker that belongs there. The panel carries a label listing which breaker types the manufacturer tested in that enclosure, and installing anything outside that list voids the listing on the whole assembly. Inspectors check this, and insurance adjusters check it after a fire.
The mechanical fit is the trap. Several brands share a stab geometry close enough that a wrong breaker clips in and looks perfectly normal. What differs is the clamping pressure on the bus stab, and low clamping pressure under load means heat at the one connection nobody can see.
This shows up most often on panels that have been added to over many years by different people. We check the label against what is actually installed on every panel we open, and we say so when the mix is wrong, whether or not that is what we were called for.
Questions we get
How do I know if I need a bigger service?
The honest test is a load calculation, not the age of the panel. If you are adding a charger, a shop, a heat pump, or a hot tub, that calculation is the first step.
What is a subpanel for?
It puts capacity where the work is. A shop or a detached garage is usually better served by one feeder and a subpanel than by several long circuits.
Who handles the utility?
We do. The disconnect and reconnect get coordinated as part of the job.
What areas do you cover?
Pinetop-Lakeside and about forty miles out from there, which covers most of Navajo County and the western side of Apache County.
Are you licensed?
Yes. We hold a C-11 commercial license, number 192532, and an R-11 residential license, number 192533. Both are current and we are insured.
Towns we cover
Based in Pinetop-Lakeside, covering about forty miles out across Navajo County and the western side of Apache County.
