A panel replacement is a decision about capacity, not about a box on the wall. The service rating, the breaker layout, the grounding and bonding, and what the house will ask of it in ten years all get settled while the cover is off — and in Greeley that conversation often ends with a different answer than the homeowner expected. Precision Service Electric replaces panels and upgrades services here, and works out whether you need a like-for-like swap or a real service upgrade before quoting. Call 970-593-3190.
Why Greeley Panels Get Replaced
Four reasons, and only two of them are urgent. The equipment has failed: breakers that trip without a load, a panel warm to the touch, scorch marks at a breaker, a burning smell. The equipment is a known hazard: certain Federal Pacific and Zinsco lines are defective by design, and no new breaker makes them safe. The panel is full and the house needs circuits it cannot carry. Or the service itself is too small for what the house now runs.
Greeley’s housing stock splits the question neatly. Homes in the older grid near downtown and the university frequently still carry a 100-amp service, a fuse-to-breaker conversion, or a panel whose breakers are no longer manufactured. The subdivisions built from the 1970s onward are more likely to have 200-amp service with physical room — and still run out of usable spaces because of how the original electrician laid the circuits out.
Repair or Replace: How to Tell
Signs the Panel Is Failing
Breakers that trip for no obvious reason, a panel that is warm or smells hot, scorching or melted insulation at a breaker, and lights that dim when an appliance starts. Any of these means an electrician looks at it now rather than at the next renovation.
Panels That Are a Known Hazard
Some panel lines are defective by design rather than by age — Federal Pacific Stab-Lok and Zinsco equipment in particular. New breakers in the old enclosure do not make them safe; the remedy is a full replacement, or a listed replacement interior where the enclosure is compatible and such a part exists for it. A home inspector will flag the original equipment at sale either way. Aluminium branch wiring is a separate problem: a new panel does not repair the terminations inside the walls, and those are assessed and repaired on their own.
Panels That Are Merely Full
A full panel on a healthy service is a different problem from a failing panel. Sometimes a subpanel is the answer, sometimes a tandem breaker is legal and adequate, and sometimes the honest answer is that the house needs more service capacity. “You need a new panel” and “you need a service upgrade” are not the same sentence, and the difference is thousands of dollars.
Like-for-Like Swap or Service Upgrade?
A like-for-like replacement puts a new panel of the same rating in place of the old one: same service size, same feed, new equipment, breakers re-terminated, grounding and bonding brought up to current requirements. That is the right job when the service is adequate and the equipment is the problem.
A service upgrade changes the rating — commonly 100 amps to 200, sometimes to 320 for a house adding an electric vehicle charger, a heat pump and a shop. It brings a new meter base, new service-entrance conductors, and a conversation with Xcel Energy about the service drop. It costs more, and it is the only honest answer when the load calculation says the house has outgrown what it has.
What the Load Calculation Actually Does
The calculation starts from square footage and adds the major loads: range, dryer, water heater, heating and cooling, and any large motor circuits. The existing service is compared against that total. A house with gas heat, a gas range and no hot tub can often stay at 100 amps comfortably; a house with electric resistance heat or a heat pump plus an EV charger usually cannot. The arithmetic — not the age of the panel — decides.
Why a Bigger Panel Is Not Automatically More Capacity
A 200-amp panel fed by a 100-amp service is still a 100-amp house. The panel is a distribution device; the service is the capacity. This is the single most common misunderstanding in panel quotes, and it is worth asking any contractor to point at which of the two they are selling you.
Grounding, Bonding and Surge Protection
A panel replacement is the moment the grounding electrode system gets inspected properly: the ground rod or ufer connection, the water-pipe bond, the equipment-grounding conductors, and the bonding of any metal gas piping. In a house that has been added onto two or three times, this is where surprises live.
Whole-home surge protection is a device installed at the panel. It is not a substitute for grounding, and it is not a warranty against every surge, but it is inexpensive relative to the equipment it protects and it is far easier to install while the panel is open.
Permits and Inspection in Greeley
Electrical work of this scope is permitted work. The City of Greeley Building Inspection department issues the permit at 1100 10th Street, Suite 114 — 970-350-9830, and applications and inspections run through the City’s eTRAKiT portal at trakit.greeleygov.com.
One scheduling fact worth knowing if you are comparing quotes across a calendar: the City publishes that a contractor licence will be required for permits starting January 1, 2027. Work permitted before that date is unaffected, but a job that slips into next year needs a contractor who holds the licence the City will require.
Inspection happens with the cover off and the panel labelled. A clean inspection is not a formality — it is the point at which an independent inspector confirms the terminations, the grounding, and the breaker sizing someone else installed.
What the Job Actually Involves
Before the Day
A site visit establishes the service size, the meter location, the condition of the existing wiring at the panel, and whether the drop or the meter base needs replacement. The written quote should state the panel rating, whether the service is being upgraded, what happens to the meter base, and how long the power will be off.
On the Day
Power is off for the working window — typically several hours for a like-for-like swap, longer when the meter base and service conductors change. The utility may need to disconnect and reconnect. Circuits are labelled as they are re-terminated, which is the difference between a panel you can live with and a panel nobody can read.
After the Inspection
Labelling is finished, the inspection is closed, and any circuits that were previously doubled up are documented so the next electrician is not guessing.
What Drives the Cost
Panel work is priced from scope, not from a menu. The variables that move the number most: like-for-like versus a service upgrade; whether the meter base and service-entrance conductors are replaced; the condition of the existing branch wiring where it lands in the panel; whether the panel has to be relocated to meet clearance requirements; access and finish repair; and permit fees.
A house with a failed 100-amp panel in a finished basement wall and a house with a 200-amp panel on an exterior wall are not the same job, and a quote that ignores the difference is a quote that will change.

Panel capacity questions rarely arrive alone. If a standby generator is part of the plan, its transfer switch lands in this panel and the standby generator installation in Greeley page covers that side of the work. If the new circuits are for a car, the EV charger installation in Greeley page covers circuit sizing and the load calculation behind it.

Frequently Asked Questions
How long will the power be off?
A like-for-like panel swap is usually a working day. A service upgrade that involves the meter base and the utility’s drop can run longer, and the utility’s own scheduling is part of the timeline. The written quote states the expected window so you can plan refrigeration and any medical equipment.
Do I need a permit for a panel replacement in Greeley?
Yes. Panel replacement is permitted electrical work, applied for through the City of Greeley’s eTRAKiT portal and inspected by the City. The permit is part of the job, not an extra.
Can you replace the panel without upgrading the service?
Often, yes — that is a like-for-like replacement, and it is the correct scope when the service rating is adequate. If the load calculation says the house has outgrown the service, a new panel of the same rating will not fix it.
My panel is a Federal Pacific or Zinsco — is that urgent?
It is not a same-day emergency, but it is not something to defer indefinitely either. Those panels are defective by design: replacement breakers alone do not resolve the original equipment’s hazards. The fix is a full replacement, or — where the enclosure is compatible and the part is listed for it — a listed replacement interior. Either way it is flagged at resale, so plan the work rather than waiting for a failure.
Will a new panel add capacity for an EV charger?
Only if the service has capacity to give. The charger circuit is added to the load calculation like any other large load; if the service is already near its limit, the answer is a service upgrade, load management, or a smaller charger circuit — and that is decided by the numbers, not by the panel’s sticker.
Do you handle the utility coordination?
Yes. Where the service changes, the disconnect and reconnect with Xcel Energy is scheduled as part of the job, and the inspection sequence is arranged so the utility reconnects on a passing inspection rather than leaving the house dark overnight.
“I was in need of cord for my garbage disposal to reach the electrical outlet after a plumber put my dishwasher back without hooking up the disposal and left. Calvin and Cade were in the neighborhood for an appointment so went down and asked for help and they changed out the electrical cord and SAVED my Day! They were very professional, knowledgeable and just amazing young men! I would recommend them for your electrical needs! I will definitely use them if I need assistance again! WOW! Still decent companies and people in this world! THANK YOU CALVIN and CADE!!”
