Final answer:
Receptacles along any continuous wall space should not be more than 6 feet apart, aligning with NEC standards. Older spacing guidelines suggested 5 diameters side-to-side and 7-8 deep, while newer suggestions go up to 8 side-to-side and 15 deep.
Step-by-step explanation:
Receptacles must be no farther than 6 feet apart along any continuous wall space, according to the National Electrical Code (NEC). This ensures accessibility to power for appliances and equipment while reducing the need for extension cords, which can be a safety hazard. However, there was an older "rule of thumb" which suggested spacing could be 5 diameters side-to-side and 7-8 diameters deep. Whereas, more recent work suggests an even greater spacing of up to 8 diameters side-to-side and 15 diameters deep between receptacles.
