Residential electrical safety concerns focus on the risks of overloading circuits and the improper use of extension cords. Standard US outlets typically provide 1,800 to 2,400 watts, but the National Electrical Code recommends an 80% continuous load limit to prevent overheating and fire risks.

Safety guidance emphasizes that high-wattage appliances, such as refrigerators, air conditioners, and heaters, should ideally be plugged directly into wall sockets. Using extension cords for these devices, or daisy-chaining multiple cords together, increases the risk of electrical arcing and domestic fires.
