As winter rolls around and the temperatures start dropping, you may notice your electrical system behaving erratically. That’s because frigid weather is capable of putting stress on every component, leading to a variety of potential issues. Here are six clear signs that cold weather is compromising your electronics and what you can do to protect them!
- Reduced Battery Performance
Many critical indoor appliances that use batteries, such as alarms and sump pumps, struggle in freezing weather. The lead-acid inside a battery must maintain a delicate chemical balance, and cold temps may drain its voltage reserves too fast. The solution: install high-quality batteries that can withstand extreme cold and always have some backups on hand.
- Expanded Insulation
During drastic temperature changes, your home’s insulation can contract and expand. This can put added pressure on the wires, potentially even crushing them. Contraction also makes insulation stiffer and less able to protect the wiring from moisture. Make sure to use insulation appropriate for cold weather, such as cellulose or fiberglass.
- Breaker Issues
When too many high-wattage devices tax the line capacity, breakers may trip. This is particularly common in winter, when heating equipment comes online. The breakers themselves can have temperature-dependent tolerances, usually between 30 and 110°F. Test your breakers regularly to ensure they trip at the right amps and upgrade your breaker box if necessary.
- Added Condensation
Due to the differences in temps between external and internal air, condensation in electrical components is fairly common in winter. Water droplets can wreak havoc on your electronics in many ways, from increasing corrosion to causing electrical shorts. You can prevent condensation by investing in proper ventilation to reduce the moisture in the air.
- Power Outages
During deep winter, some utility providers struggle to keep up with surging demand. The older their infrastructure is, the more likely you’re to experience a prolonged blackout due to a downed power line or equipment failure. In situations like these, it helps to have backup solutions such as UPS batteries or generators automated to run the essentials.
- Outdoor Wiring Problems
The elements can be a major issue for your outdoor connection elements. Wind, snow, and hail will all beat up connectors over time, loosening them in the process. Corrosion and rodents can also do a number on the unprotected metal parts and wires. Make sure your yard boxes, shed lines, and swimming pool equipment are properly sealed and covered for the climate.
