Winter storms in Superior and throughout Boulder County aren’t just inconvenient, they can be downright dangerous for your home’s electrical system. Heavy snow, ice accumulation, and plunging temperatures put serious stress on wiring, panels, and outdoor components, sometimes leading to power outages, electrical fires, or costly damage that could’ve been prevented.
We’ve seen it happen too many times: a homeowner waits until the power flickers out during a blizzard to realize their electrical panel hasn’t been inspected in a decade. Or they discover that the surge protector they bought at a big-box store years ago isn’t actually protecting anything anymore. The good news? With some proactive preparation, you can significantly reduce the risk of winter storm-related electrical problems and keep your family safe when the weather turns nasty.
In this guide, we’ll walk you through the essential steps to winterize your home’s electrical system, from panel inspections and surge protection to outdoor equipment and emergency preparedness. Whether you’re a longtime Superior resident or new to Colorado’s unpredictable winters, these tips will help you weather whatever Mother Nature throws your way.
Understanding Winter Storm Risks to Electrical Systems
Before we jump into specific preparations, it helps to understand exactly what winter storms can do to your electrical system. Knowledge is power, literally, in this case.
Ice and Snow Accumulation
Heavy ice buildup on power lines and outdoor wiring is one of the most common causes of winter outages. Even a quarter-inch of ice can add significant weight to lines, causing them to sag or snap. Inside your home, the sudden loss and restoration of power creates voltage spikes that can damage sensitive electronics and appliances.
Temperature Fluctuations
Dramatic temperature swings cause metal components to expand and contract repeatedly. Over time, this can loosen electrical connections in your panel, outlets, and junction boxes. Loose connections create resistance, which generates heat, and heat is the enemy of electrical safety.
Moisture Infiltration
Melting snow and ice can seep into outdoor electrical boxes, conduit, and even interior walls if there are gaps in your home’s envelope. Water and electricity don’t mix, and moisture in the wrong places can cause short circuits, corrosion, and ground faults.
Increased Power Demand
When temperatures drop, your heating system works overtime. Space heaters come out of storage. Electric blankets get plugged in. All that extra demand can overload circuits that were already operating near capacity, tripping breakers or, worse, causing overheated wiring behind your walls.
Here in Boulder County, we experience all these conditions regularly between November and March. That’s why preparing your electrical system before storm season is so critical.
Inspecting Your Electrical Panel and Wiring
Your electrical panel is the heart of your home’s power distribution system. If it’s not in good shape, everything downstream suffers. Here’s what we recommend checking before winter hits.
Panel Age and Condition
If your home was built before the 1990s and still has its original panel, it’s worth having a professional evaluation. Some older panels, particularly certain Federal Pacific and Zinsco models, have known safety issues and may not trip properly during overloads. Even if your panel doesn’t fall into a problematic category, components degrade over time.
Look for visible signs of trouble: rust or corrosion on the panel box, scorch marks around breakers, or a burning smell when you open the panel door. Any of these warrant immediate professional attention.
Breaker Functionality
Test each breaker by flipping it off and back on. A properly functioning breaker should snap firmly into position. If any feel loose, won’t stay reset, or make buzzing sounds, that’s a red flag. Breakers that won’t reset are one of the most common electrical emergencies we handle, and discovering the problem before a storm is far better than finding out in the middle of one.
Wiring Inspection
Visible wiring in your attic, basement, or crawl spaces should be checked for damage. Look for frayed insulation, rodent chew marks, or areas where wires are pinched or kinked. Damaged wiring is a fire hazard year-round, but the increased power demands of winter make failures more likely.
Also check that all junction boxes are properly covered. Missing covers allow dust, moisture, and pests to access wire connections, none of which you want.
Circuit Capacity
Think about how you use electricity during winter months. If you’re regularly tripping breakers when running the space heater and microwave simultaneously, your circuits may be overloaded. This is especially common in older homes that weren’t designed for today’s electrical demands. Adding dedicated circuits for high-draw appliances can prevent nuisance trips and reduce fire risk.
Surge Protection and Power Outage Preparedness
Power surges during winter storms are practically inevitable. When utility power drops and returns, sometimes multiple times during a single storm, each restoration can send a voltage spike through your home’s wiring. Here’s how to protect your equipment and prepare for outages.
Whole-House Surge Protection
Plug-in surge protectors are fine for computers and TVs, but they only protect what’s plugged into them. For comprehensive protection, consider a whole-house surge protector installed at your electrical panel. These devices intercept voltage spikes before they reach any of your circuits, protecting everything from your refrigerator to your HVAC system.
The investment is relatively modest compared to replacing a fried furnace control board or smart home hub. We install whole-house surge protection regularly, and homeowners are often surprised how affordable it is.
Uninterruptible Power Supplies (UPS)
For critical equipment like sump pumps, medical devices, or home office setups, a UPS provides battery backup during brief outages and conditions power during surges. Size your UPS based on the wattage of connected devices and how long you need them to run during an outage.
Installing a Backup Generator Safely
A backup generator can be a lifesaver during extended winter outages, but improper installation is dangerous. Portable generators produce carbon monoxide and must never be operated indoors or in enclosed spaces like garages. We’ve unfortunately seen the tragic consequences of this mistake.
For permanent solutions, a standby generator with an automatic transfer switch is the gold standard. The transfer switch prevents backfeeding, sending power back into utility lines, which can electrocute utility workers and damage your home’s wiring when grid power returns.
Key generator safety points:
- Never connect a portable generator directly to your home’s wiring without a transfer switch. This is a code violation and serious safety hazard.
- Position portable generators at least 20 feet from windows, doors, and vents.
- Use heavy-duty outdoor-rated extension cords if running appliances directly from a portable generator.
- Have standby generators professionally installed and maintained. We handle generator installations and can ensure everything meets electrical code requirements.
If you’re considering a generator installation, fall is the ideal time, before demand spikes and supply chains get strained by winter storm season.
Protecting Outdoor Electrical Components
Your home’s exterior electrical components take the brunt of winter weather. A little preparation now can prevent headaches, and expensive repairs, later.
Outdoor Outlets and Covers
All outdoor receptacles should have weatherproof covers, not just the flip-up type that only protect when nothing’s plugged in. Look for “in-use” covers that seal around cords. While you’re at it, test the GFCI protection on outdoor outlets by pressing the test button. If the outlet doesn’t trip, or won’t reset afterward, the GFCI may be faulty.
Exterior Lighting
Inspect all outdoor light fixtures for cracked lenses, missing gaskets, or damaged wiring. Water infiltration into fixtures causes shorts and accelerated corrosion. Replace any bulbs that have burned out, winter’s shorter days mean you’ll be relying on outdoor lighting more frequently, and you don’t want to discover a dead light during an icy evening.
LED bulbs are worth considering if you haven’t already switched. They perform better in cold temperatures than incandescent bulbs and use a fraction of the energy.
Landscape Lighting and Wiring
Low-voltage landscape lighting is generally safe, but check transformer connections and buried wiring for damage. Rodents sometimes chew through landscape wire, and freeze-thaw cycles can heave connections apart. Make sure transformers are elevated or protected from standing water and snow accumulation.
Air Conditioning Units and Heat Pumps
If you have a heat pump, keep the outdoor unit clear of snow and ice buildup. The defrost cycle handles normal accumulation, but heavy snow can overwhelm it. Don’t cover the unit with a tarp, this traps moisture and can cause more problems than it solves. Simply brushing off heavy snow after storms is sufficient.
For central AC units you won’t use until spring, some homeowners cover just the top to prevent debris accumulation. But again, avoid wrapping the entire unit, which invites condensation and critter habitation.
Essential Emergency Supplies and Safety Measures
Even with the best preparation, winter storms can knock out power for hours or days. Having the right supplies and knowing basic electrical safety will help you manage until power returns, or until help arrives.
Emergency Kit Essentials
Every Boulder County household should have these items readily accessible:
- Flashlights and extra batteries (avoid candles if possible, they’re a leading cause of house fires during outages)
- Battery-powered or hand-crank radio for weather updates
- Fully charged portable phone chargers
- Non-perishable food and manual can opener
- Bottled water (at least one gallon per person per day for three days)
- Warm blankets and extra layers
- First aid kit with any necessary medications
Store your emergency kit somewhere accessible, not in the basement you can’t safely reach if the power’s out and stairs are dark.
Electrical Safety During Outages
When the power goes out:
- Turn off or unplug major appliances and electronics. This prevents damage from surges when power returns and reduces load on the grid during restoration.
- Leave one light switched on so you’ll know when power returns.
- Keep refrigerator and freezer doors closed. A full freezer maintains safe temperatures for about 48 hours: a half-full freezer, about 24 hours.
- Never use gas ovens or stovetops for heating. Carbon monoxide poisoning is a serious risk.
- Stay away from downed power lines, always assume they’re energized.
After Power Returns
Wait a few minutes before turning appliances back on, and do so gradually to avoid overloading circuits. If you notice burning smells, sparking outlets, or breakers that won’t reset after power restoration, contact a licensed electrician immediately. These are signs of potential electrical damage that needs professional assessment.
