Frequently Asked Questions

I see the power lines come to my house on a mast from the pole. What should I know about this overhead service?

Overhead service masts are common in the Riverside District. The mast head and weatherhead must be intact and properly sealed to prevent water from tracking down the service cables into your panel—a frequent cause of corrosion. We also check that the mast is securely braced; Illinois ice loads can weigh down lines and pull poorly secured masts from the structure. During any service upgrade, the mast and its attachment are replaced to meet current ComEd and structural codes for overhead service.

I have an old 100-amp panel and want to add a Level 2 EV charger. Is my current electrical system capable?

A 100-amp service from 1988 cannot safely support a 40-50 amp Level 2 EV charger alongside a modern home's other loads, like central air or an electric range. The math simply doesn't work without risking constant tripping or overheating. Furthermore, many homes in this era were fitted with Federal Pacific panels, which are a known fire hazard due to breakers that fail to trip. A full service upgrade to 200 amps is the necessary first step, which includes replacing the panel, meter socket, and all service entrance conductors.

The power just went out and I smell something burning near the panel. How fast can a Master Electrician get here?

For an immediate hazard like a burning smell, our dispatch prioritizes your call. From our shop near Miller Point Park, we can typically be at your Riverside District home in 5 to 8 minutes using IL-31. Upon arrival, we'll first secure the main breaker to stop the hazard, then diagnose the source—often a failing breaker connection or overheated bus bar in the panel. Do not attempt to reset the breaker; wait for our assessment to prevent a potential fire.

How can I prepare my home's electrical system for a McHenry winter with ice storms or a summer brownout?

Winter ice can bring down overhead lines, while summer AC use strains the grid. For winter, ensure your generator transfer switch is installed correctly and inspected; a common error is back-feeding power into the grid, which is deadly to line workers. For summer reliability, have your central air conditioner's dedicated circuit and breaker tested for tight connections to prevent failure during peak demand. Consider a standby generator with an automatic transfer switch for seamless backup power during extended outages in either season.

We live in the rolling river valley near Miller Point Park. Could the terrain affect our home's electrical grounding?

Yes, the soil conditions in a river valley can impact grounding electrode performance. Rocky or constantly moist soil alters the resistance of your grounding system, which is critical for safety and surge dissipation. We perform ground resistance testing to ensure your home's grounding rods or UFER (concrete-encased) electrode, if present, meet NEC requirements. Proper grounding is especially important here to protect against lightning-induced surges that can travel through the land.

My lights in McHenry flicker during thunderstorms. Is this a ComEd problem or something in my house?

ComEd's grid experiences moderate surge risk from our seasonal thunderstorms, which can cause momentary flickers. However, consistent flickering, especially when you run an appliance, often points to a loose connection in your home's wiring—at a breaker, a splice, or even the utility's connection at the mast. These faults generate heat and damage components over time. Installing a whole-house surge protector at your main panel is a critical defense for your smart home electronics, but diagnosing internal wiring issues requires a professional inspection.

My home in the Riverside District was built in 1988. Is the 38-year-old wiring still safe for computers and big-screen TVs?

A home of this age in McHenry likely has NM-B (Romex) cable with a ground wire, which was the standard. The core insulation and conductors are generally sound if undisturbed, but capacity is the main concern. Original 15-amp kitchen and laundry circuits from 1988 are now loaded with high-wattage modern appliances, pushing them beyond their design. We should test for proper grounding at all outlets and consider adding dedicated circuits for home offices and entertainment centers to prevent overloads.

What permits and codes are involved if I need to replace my electrical panel in McHenry?

All panel replacements require a permit from the McHenry Building Department and a final inspection. As a Master Electrician licensed by the Illinois Department of Financial and Professional Regulation, I handle the permit application and ensure the installation complies with the current NEC 2023, which mandates AFCI protection for most living areas and specific surge protection requirements for dwelling units. This process protects you by guaranteeing the work is documented, inspected, and safe, which is also required by your homeowner's insurance.
