Electrical Panel Upgrades in Murray, UT: What Murray Homeowners Need to Know Before Calling an Electrician
Murray's housing stock is older than most homeowners realize — a large share of single-family homes in the city were built between the 1940s and 1970s, when 60A or 100A electrical service was considered plenty. Today, that same service has to power central air, multiple appliances, home offices, and often an EV charger. That mismatch between original capacity and modern load is the most common reason Murray homeowners start asking about panel upgrades.
How Do You Know If Your Panel Is Undersized?
Your panel is likely undersized if breakers trip often, lights dim when large appliances start, or an electrician has flagged it during a service call. These symptoms point to a capacity problem, not just a wiring problem.
Breakers that trip and won't reset are one of the clearest signs. So are flickering or dimming lights when your HVAC kicks on — that voltage sag happens because the panel is delivering close to its maximum amperage and a new load pushes it over the edge.
Also check the panel itself. Burn marks, rust, heat radiating from the box, or a buzzing sound all indicate a panel that is struggling or failing. If your home still has a Zinsco or Federal Pacific (Stab-Lok) panel — brands common in Murray's mid-century homes — those are known safety hazards that warrant replacement regardless of your current load.
Another red flag is double-tapped breakers , where two wires share a single breaker terminal. That is a workaround for running out of circuit slots, not a real solution, and it creates a fire risk.
What Does the Upgrade Process Actually Involve?
A panel upgrade in Murray follows a defined sequence: permit first, then the physical swap, then a city inspection before power is restored for good. Skipping any step creates legal and insurance liability.
Your licensed electrician pulls the permit through Murray City Building Services before work begins — this is standard practice and something a qualified electrician handles on your behalf. Work must comply with the National Electrical Code (NEC) as adopted by Utah.
On the day of the upgrade, Rocky Mountain Power (Murray's utility) temporarily disconnects service at the meter. The electrician installs the new main panel, replaces breakers, and rewires circuits. Expect to be without power for roughly 4 to 8 hours on that day — a realistic and manageable window for most households.
After the work is done, a Murray City electrical inspector reviews it before Rocky Mountain Power reconnects the service permanently. That inspection is the final confirmation that the installation meets code. In older Murray homes, the upgrade sometimes also requires replacing the meter base or service entrance cable, which adds scope but is often unavoidable given the age of the components.
If you are also planning new circuits or service work after the upgrade, residential electrical installation in Murray covers what comes next once your panel has the capacity to support it.
Does Adding an EV Charger Require a Panel Upgrade?
A Level 2 home EV charger needs a dedicated 240V circuit drawing 40–50 amps. A 100A panel running a modern home's baseline load usually has no room for that circuit, so the panel upgrade has to come first.
Murray's proximity to I-15 and its commuter corridors has driven real EV adoption in the area, and charger installations are one of the most common reasons homeowners discover their panel is at capacity. The practical sequence is: upgrade the panel to 200A service, then add the charger circuit. One licensed electrician, one coordinated permit pull, one visit plan.

Murray's Climate and Housing Age Make Timing Matter
Utah's hot summers push HVAC systems hard, and that seasonal load spike is often when an undersized panel reveals itself through tripped breakers or dimming lights. Planning an upgrade before summer — or before a basement finish or home addition project — avoids the most disruptive timing.
Many Murray homeowners are finishing basements or adding space rather than buying new, which is a natural discovery moment: a contractor or electrician assesses the panel and flags that the existing service cannot safely support the added circuits. If that is your situation, it is worth understanding what home additions in Murray typically require from an electrical capacity standpoint before the project starts.
Why Permits and Licensed Electricians Are Non-Negotiable
Utah requires a state electrical license — journeyman or master level — for panel upgrade work. Unlicensed work means no permit, no inspection, and in many cases a voided homeowner's insurance policy if an electrical fire occurs. It also creates disclosure liability when you sell.
A licensed electrician familiar with Murray City's process handles the permit pull, schedules the Rocky Mountain Power disconnection, and books the city inspection. You are not managing those moving parts alone. Ask any electrician you hire for their state license number, proof of insurance, and permit confirmation before work begins — a qualified contractor will have all three ready.
Upgrading from a 100A to a 200A panel gives your home the capacity to support how modern households actually operate — safely, with room for future circuits and without the daily friction of tripped breakers or dimming lights.
