Your Home's Electrical Safety Starts at the Panel.
The electrical panel sitting in your basement, utility room, or garage is the most important safety device in your home. It controls every circuit, protects every wire, and stands between your household and the electrical faults that cause fires. Yet most homeowners in Lewiston, CA never think about their panel until something goes wrong — and by then, the consequences can be severe.
Dinis Electric Inc specializes in electrical panel upgrades and repairs for homes and businesses across Lewiston. Whether your panel is outdated, overloaded, tripping constantly, or simply hasn't been inspected in years, our licensed electricians provide honest assessments, clear recommendations, and professional work that protects your property for the long term. We don't alarm people unnecessarily — but we do tell them the truth about what's in their walls.
Click Here to Call (888) 267-4161The most common panel upgrade request we receive in Lewiston, CA is moving from a 100-amp service to a 200-amp service panel — and for good reason. Homes that were wired decades ago with 100-amp service were designed for a fraction of the electrical load modern households carry. EV chargers, induction ranges, heat pump systems, home offices, and multiple high-draw appliances simultaneously push older panels to their absolute limit. Our licensed electricians assess your current load, coordinate with your utility company for the service upgrade, install the new 200-amp panel, and restore full power — leaving your home with the capacity it actually needs.
Breakers that trip under normal load, fail to reset, or simply stop holding are protection devices that are no longer protecting you correctly. A failed breaker can allow overcurrent to reach your wiring — a condition that generates heat, damages insulation, and creates fire risk. We replace individual breakers and install new circuits with correctly rated breakers matched to the wire gauge and load they'll serve.
Fuse boxes in older Lewiston homes aren't just outdated — they're a genuine insurance and safety liability. Many insurers in Lewiston, CA will no longer write policies on homes with fuse boxes, and the limited capacity of these systems makes overloading a constant risk. We convert fuse boxes to modern circuit breaker panels completely, handling all wiring connections, grounding upgrades, and utility coordination required.
When a garage, workshop, addition, or outbuilding in Lewiston needs its own electrical distribution point, a subpanel is the correct solution. We install subpanels sized for the specific load they'll serve, with correctly rated feeder wire from the main panel, proper grounding and bonding, and a clear circuit layout that makes future work straightforward. We also diagnose and repair existing subpanels that are tripping, overheating, or underperforming.
Before recommending any panel upgrade, we perform a proper load calculation — assessing the actual electrical demand of your Lewiston, CA home against your panel's current and projected capacity. This gives you a factual basis for any decision you make about panel sizing rather than a guess or an upsell. If your existing panel can handle your needs safely, we'll tell you that.
High-draw appliances — HVAC systems, electric ranges, dryers, EV chargers, hot tubs, and large workshop equipment — require dedicated circuits that aren't shared with other loads. We install dedicated circuits from your main panel with correctly sized wire and breakers for each application, eliminating the tripping and performance issues that come from sharing circuits across heavy loads.
Arc fault circuit interrupter (AFCI) breakers detect the electrical arcing that most commonly leads to residential fires. Ground fault circuit interrupter (GFCI) breakers protect against shock in wet environments. Current electrical code in Lewiston requires both types in specific locations. We upgrade existing panels with AFCI and GFCI breakers where code mandates protection and where your system currently lacks it.
A generator connected without a proper transfer switch creates a serious risk — both to your household and to utility workers restoring power on your street. We install manual and automatic transfer switches that safely isolate your home from the grid during generator operation, protecting everyone and ensuring your backup power system operates legally and correctly in Lewiston, CA.
Whole-home surge protection at the panel level guards every circuit in your Lewiston property against voltage spikes from lightning, utility switching events, and large motors cycling. Unlike individual power strips that protect only connected devices, panel-level surge protection covers your entire electrical system — including hardwired appliances, HVAC, and lighting circuits.
Our electrical safety inspection service provides a documented assessment of your panel, branch circuit wiring, grounding system, GFCI and AFCI coverage, and service entrance condition. Every finding is prioritized by risk level and explained in plain language — giving you a clear picture of your system's current safety status and what, if anything, needs attention.

Whole-home flickering — particularly when large appliances start — often indicates a loose connection at the service entrance or main panel. This is a condition our Lewiston electricians assess and correct as a priority, as main connection faults generate serious heat.
Electrical panels operate silently when functioning correctly. A buzzing, humming, or crackling sound from your panel indicates a loose connection, an overloaded breaker, or arcing inside the enclosure — all of which require immediate inspection.
A panel that has no open breaker slots can't safely accommodate new circuits. Solutions include a subpanel addition, tandem breaker installation where the panel supports it, or a full panel upgrade to a larger enclosure.

Step 2 — Clear Options & Quote We present your options honestly — with the costs, timelines, and practical differences between them — so you can make an informed decision without pressure.
Step 3 — Permitting & Utility Coordination We pull the required permits and coordinate with your utility provider for any service upgrade work before scheduling the installation.
Step 4 — Professional Installation Our licensed Lewiston electricians complete the panel work safely and systematically, maintaining power to unaffected circuits wherever possible throughout the process.

How much does a 200-amp panel upgrade cost in Lewiston, CA?
