Questions and Answers

My Ontario home was built in 1979. Why are the lights dimming when I use my air conditioner?

Your home's electrical system is 47 years old. Original NM-B Romex wiring in College Park was sized for the era's smaller loads, not today's high-capacity appliances. A 100-amp panel from 1979 often lacks the physical space and bus bar capacity to safely add modern circuits, leading to voltage drop and tripped breakers under simultaneous demand. Upgrading the service panel is typically the first step to restore stable power.

My home has an underground service line. What does that mean for maintenance or an upgrade?

An underground lateral from SCE means your service entrance is less exposed to weather but requires coordination for an upgrade. The utility owns the cable from the transformer to your meter, while you own the conduit and wiring from the meter to the main panel. Upgrading your panel and service capacity involves a permit, a trench inspection by the city, and a scheduled disconnect/reconnect with SCE to pull new conductors through the existing conduit.

My power went out and I smell something burning near the panel. How fast can an electrician get here?

From the Ontario Convention Center area, our service route via I-10 allows for an 8-12 minute dispatch in College Park. A burning odor indicates an active fault, so shut off the main breaker at the service panel immediately. Do not restore power. We prioritize these calls to prevent potential arc faults from escalating to an electrical fire inside the wall.

My smart TV and lights keep flickering. Is this a problem with Southern California Edison?

While SCE manages the grid, flickering often starts within your home's wiring, especially with older panels under load. Grid instability from seasonal wildfire mitigation or high demand can introduce surges, but internal issues like loose connections at the main lugs are more common. A whole-home surge protector installed at the panel is critical to shield modern electronics from both external surges and internal voltage spikes.

How can I prepare my Ontario home's electrical system for summer brownouts and winter cold snaps?

Summer AC peaks strain an older 100-amp panel, increasing fire risk during brownouts when voltage fluctuates. For winter, ensure outdoor outlets are protected with weatherproof in-use covers and GFCI protection. Installing a transfer switch and a properly sized backup generator, permitted through Ontario Building and Safety, provides reliable power for essentials during extended outages in any season.

We're on the flat valley floor near the Convention Center. Does the terrain affect my home's electrical grounding?

The flat, stable soil in this part of College Park is generally favorable for establishing a low-resistance grounding electrode system. However, over decades, the connection to the ground rods can corrode or loosen, compromising the safety path for fault currents. We test the grounding electrode conductor and bonding during every panel upgrade or inspection to ensure it meets NEC 2023 standards for personal safety and surge dissipation.

I have an old Federal Pacific panel and want to install an EV charger. Is my 100-amp service enough?

No, it's not. A Federal Pacific panel is a known fire hazard due to breakers that can fail to trip, and it must be replaced for basic safety. Even with a new panel, a 100-amp service from 1979 lacks the reserve capacity for a Level 2 EV charger or a modern heat pump. A full service upgrade to 200 amps is the standard, code-compliant solution to power both your home and new high-demand appliances safely.

What permits and codes apply if I need to replace my electrical panel in Ontario?

All panel replacements require a permit from the Ontario Building and Safety Division and must be installed to NEC 2023 standards, which mandates AFCI protection for most living area circuits. The work must be performed by a contractor holding a current C-10 license from the CSLB. As the Master Electrician on record, I handle the permit filings, scheduling inspections, and providing the final certification to ensure the installation is both safe and legally compliant.
