St. George's Mojave Desert climate brings extreme summers, mild winters, and unique challenges for your home's electrical system. From peak A/C demand to monsoon-driven power surges, here are seven safety tips every St. George homeowner should keep in mind.
St. George winters get cold, and space heaters are a common way to supplement heating in older homes across Bloomington and downtown. But space heaters draw significant power, and plugging one into a circuit that is already near capacity is a leading cause of tripped breakers and electrical fires.
Always plug space heaters directly into a wall outlet — never into an extension cord or power strip. If using a space heater trips your breaker, that circuit may need to be evaluated by a licensed electrician.
Ground fault circuit interrupter (GFCI) outlets are required in bathrooms, kitchens, garages, and outdoor areas. These outlets protect you from electrical shock by cutting power when they detect a ground fault. Press the "test" button on each GFCI outlet once a month to make sure it trips properly. If it does not trip, or it does not reset, the outlet should be replaced.
Many homes in St. George, particularly in older neighborhoods, still have 100-amp electrical panels that were installed decades ago. Some may even have Federal Pacific or Zinsco panels, which have known safety issues. If your panel is more than 25 years old or carries one of these brand names, schedule an inspection. A panel upgrade may be the safest option.
Your home's electrical system usually gives warning signs before a serious problem develops. Pay attention to:
Any of these signs warrant a call to a licensed electrician. Do not ignore them — they can indicate loose connections, overloaded circuits, or damaged wiring that could lead to a fire.
St. George's Mojave Desert location means summer thunderstorms can produce power surges that damage electronics and appliances. A whole-home surge protector installed at your electrical panel provides the first line of defense. Individual surge protector power strips add a second layer for sensitive electronics like computers and TVs.
Outdoor outlets, landscape lighting, and hot tub connections are exposed to St. George's weather, including snow, rain, and temperature swings. Make sure outdoor outlets have weatherproof covers (the "in-use" type that protect the outlet even when a cord is plugged in). All outdoor circuits should be on GFCI-protected outlets or breakers. If you notice any exposed wiring, cracked outlet covers, or damaged conduit outdoors, have it repaired promptly.
Changing a light bulb or replacing a switch cover plate is fine. But anything involving your electrical panel, new circuits, or wiring behind walls should be left to a licensed electrician. Improper electrical work is a fire hazard and can create hidden dangers that show up years later. In St. George, most electrical work beyond the basics requires a permit and inspection — and only a licensed contractor can pull that permit.
A full electrical inspection is recommended every 5 to 10 years for most homes, or whenever you buy a home, plan a major renovation, or notice warning signs like flickering lights or tripping breakers. Older homes in St. George, especially those built before 1980, should be inspected more frequently.
Space heaters are safe when used correctly. Always plug them directly into a wall outlet, never into an extension cord or power strip. Use only heaters with tip-over and overheat protection. Keep them at least 3 feet from curtains, bedding, and furniture. If a space heater causes your breaker to trip, the circuit may be overloaded and should be evaluated by a licensed electrician.
Warning signs include flickering or dimming lights, frequently tripping breakers, outlets that feel warm to the touch, a burning smell near outlets or switches, discolored outlet covers, buzzing sounds from the panel, and lights that flicker when large appliances turn on. If you notice any of these, contact a licensed electrician in St. George for an evaluation.
