Common Questions
Why do the lights in my 1979 South Shrewsbury home dim when the air conditioner kicks on?
Your electrical system is now 47 years old. Homes built in South Shrewsbury around 1979 were wired with NM-B Romex for the era's needs, which didn't include today's high-draw appliances. A 100A service panel and original circuits can struggle with simultaneous loads from central air, modern kitchen gadgets, and home office equipment, causing voltage drops you see as dimming lights. This is a clear sign your capacity is being maxed out.
How can I prepare my home's electrical system for a bad ice storm and winter brownouts?
Winter peaks strain the grid. For ice storms, ensure your generator inlet is installed by a licensed electrician with a proper transfer switch to prevent back-feeding the grid, which is illegal and deadly. Given our lows near 5°F, consider a hardwired backup for your heating system. Proactive surge protection also safeguards electronics from the grid instability that often accompanies storm-related outages.
What's involved in getting a permit for an electrical upgrade from the Shrewsbury Building Department?
Any major work like a panel replacement or service upgrade requires a permit from the Shrewsbury Building Department. As a Master Electrician licensed by the Massachusetts Board, I handle the entire process: filing detailed plans that comply with the 2023 NEC, scheduling inspections, and ensuring the work passes. This red tape is crucial—it verifies the safety and legality of the installation for your protection and for home insurance.
My smart devices keep resetting. Is this a problem with SELCO's power quality?
It could be. SELCO provides reliable power, but the Shrewsbury grid experiences moderate surge risk from seasonal ice storms and normal fluctuations. These micro-outages and voltage spikes are often imperceptible to lights but can easily disrupt sensitive electronics like routers, computers, and smart home hubs. Installing a whole-house surge protector at your main panel is the most effective defense.
I see the power lines come to my house on a mast. What does that mean for service reliability?
Your overhead mast service is standard for the area. It means your home is fed by utility lines running from the pole. While cost-effective, this setup is more exposed to weather and tree contact than underground service. We regularly inspect the mast head, conduit, and weatherhead for integrity, as these are entry points for moisture that can cause internal damage or outages.
What happens if I call for an emergency like a burning smell from an outlet?
For a critical emergency in South Shrewsbury, dispatch starts from a central location like Dean Park. From there, we take the Mass Pike (I-90) for the fastest route, typically reaching homes in your area within 8 to 12 minutes. Our first move is to secure the main power at the meter to eliminate the immediate fire hazard before diagnosing the faulty circuit.
I have an old Federal Pacific panel. Is it safe to add an EV charger or a heat pump?
Installing a Level 2 EV charger or a heat pump on a Federal Pacific panel is not safe and likely violates code. These panels are known for faulty breakers that fail to trip during overloads, creating a major fire risk. Furthermore, your 100A service from 1979 lacks the spare capacity for these high-demand appliances. A full service upgrade and panel replacement are required first.
Could the heavy tree canopy around Dean Park affect my home's electricity?
Yes, a heavy tree canopy directly impacts electrical health. Branches contacting overhead service lines can cause flickering, interference, and are a primary cause of outages during wind or ice events. For your home's grounding, rocky soil common in this area can make achieving a low-resistance connection to earth more difficult, which is critical for surge protection and safety.
