The "2-6-12 rule" is an informal mnemonic used in residential electrical planning to remember key National Electrical Code (NEC) spacing and placement requirements for standard wall receptacles: no point along a floor line can be more than 2 feet away from a receptacle (meaning any wall space 2 feet or wider requires an outlet), doorways and hall spaces have specific clearance guidelines, and standard spacing mandates that outlets are placed such that no appliance cord has to stretch more than 6 feet to reach power. This ensures safe, accessible power distribution without dangerous extension cord use. Verification: Measure wall spans and outlet intervals during room planning to confirm full compliance with local electrical spacing codes.
