In the illustration linked from the NEC it shows 4 feet between receptacles.The code states "Receptacle outlets shall be installed so that no point along the wall line is more than 600 mm (24 in.) measured horizontally from a receptacle outlet in that space."

Clear as mud. once again the NEC manages to make a ruling even more muddled than it ever was to begin with.


(1) Wall Counter-top Spaces. A receptacle outlet shall be installed at each wall counter-top space that is 300 mm (12 in.) or wider. Receptacle outlets shall be installed so that no point along the wall line is more than 600 mm (24 in.) measured horizontally from a receptacle outlet in that space. See related Illustration

Exception: Receptacle outlets shall not be required on a wall directly behind a range, counter-mounted cooking unit, or sink in the installation described in Figure 210.52(C)(1).
